Surprisingly, there does not appear to be a comprehensive source of information relating to methamphetamine. While no list is ever complete, this one attempts to answer technical questions related to the chemical methamphetamine. Unfortunately, there tends to be a great deal of street lore that is blatantly wrong about methamphetamine and similar compounds. This document also attempts to point out some of the more common myths, and provide rational explanations.
Do not use this information. I am not a chemist. This is for informational purposes only. Use of this information for illegal purposes is not condoned. The author makes no warranty, expressed or implied, of the suitability of this information for any particular purpose. The author does not endorse the abuse of any drugs, legal or otherwise.
This information has been gathered from openly available sources.
This is a preliminary document and should be considered fictitious until proven otherwise.
Methamphetamine (also known as speed, meth, crystal, crank, and sometimes confusingly called ice) is a chemical widely known for its stimulant properties on the human body. It is frequently confused with other drugs that share similar symptoms, including amphetamine, 4-methyl-aminorex, ephedrine, caffeine, and other chemicals, both legal and illegal.
In this document, we shall refer to the drugs by their common chemical names, rather than by “street names”, since the street names do not have a one-to-one correspondence to actual chemicals. For example, the term “speed” can mean methamphetamine or amphetamine. The term “ice” is generally considered to apply to 4-methyl-aminorex, but is often used to refer to relatively pure (and in some cases, not so pure) forms of methamphetamine.
We shall use the term “methamphetamine” to refer to the substance in either its free base (i.e. simple, unadorned) or salt (usually hydrochloride) form. When precision is needed, we shall explicitly state one form or the other.
This is one of the most difficult sections to write, partially because there is very little “science” involved. The literature gives conflicting reports, due to the fact that many criterion are subjective, and probably also due to confusion over terminology.
The pharmacological effects of methamphetamine are very similar to those of similarly structured molecules.
Methamphetamine can be taken orally, snorted, smoked or injected, in approximately increasing order of immediacy of onset.
Onset can be immediate (in the case of injection), or can take as long as 30-40 minutes if ingested orally.
Duration is subjective, but is probably on the order of 4 – 8 hours. Delayed absorption (for example, due to oral ingestion) can prolong the effects relative to time of administration. Of course, larger doses last longer due to the fact that it is removed from the blood at a finite rate.
The length of time that methamphetamine will stay in the plasma (blood) is between 4 to 6 hours. It can be detected in the urine one hour after use and up to 48 hours after use.
A toxic reaction (or overdose) can occur at relatively low levels, 50 milligrams of pure drug for a non-tolerant user. Different peoples’ metabolisms work at different rates, and drug strengths vary, so there is no way of stating a “safe” or “unsafe” level of use.
These include euphoria, hyperexcitability, extreme nervousness, accelerated heartbeat, sweating, dizziness, restlessness, insomnia, tooth grinding, incessant talking, and other effects.
Methamphetamine and other CNS stimulants have strong bronchodilation effects. Vasoconstriction (tightening of blood vessels) and pupil dilation are also common. Elevated blood pressure, heart rate, and other general symptoms of increased sympathetic nervous activity.
The physical effects are almost assuredly due to interactions between the amphetamine structure and human physiology, probably due to the similarity to adrenaline (epinephrine).
Mental capacity is not diminished directly by the drug. In fact, some studies have shown slight increases in mental capacity on simple tasks. It has been prescribed for attention deficit disorder, among other things.
Confusing reports here tend to center around the effects of fatigue on mental capacity.
Emotional responses may range from euphoria to anger and paranoia. Preliminary doses tend to produce the former, while continued use (e.g. for three or more days) tends to produce the latter.
It appears that these feelings may be linked to the neurotransmitters dopamine and/or serotonin, although I have not seen a good reference on this yet.

This is the easiest section to write, and the most fun, since I can be relatively sure of the facts.
All information is on free base unless otherwise noted.
Methamphetamine Free Base:
- Chem Abstract Service (9th+ CIP) uninverted name:
- Previous name:
- Alternate Names:
- d-deoxyephedrine (e.g. right-handed ephedrine, minus an oxygen)
- Methedrine (many others)
- Methamphetamine Free Base:
- Hill Convention:
- Reduction of ephedrine or pseudoephedrine
- Reducing condensation product of BMK and methylamine
- Synthesis from D-phenylalanine
- RED: The product was made from pseudoephedrine, and the red coloring of the tablet was not adequately washed away (it is difficult)
- ORANGE: Ephedrine sulfate was used, and some of the sulfate was reduced to sulfur.
- PURPLE: Iodine from a phosphorus-iodine reaction was not washed out.
- GREEN: Copper (or other metallic) salts somehow made their way in to the mixture, probably due to the reaction vessel used in the manufacture.
- BROWN: Oxidized red coloring (see above), or tablating agent was present in the reduction.
- Same as water: DL-methamphetamine (or other inactive) Most likely made from P2P (methamphetamine) or DLPA (phenylalanine). The DLPA-crank may in fact only be dl-amphetamine. Might be 100% cut [read: nothing] also…
- Same as Vicks: You’ve been ripped off ! -or- there’s so much unchanged ephedrine as to cancel the dextrorotary effects of the meth (l-ephedrine, when reduced, is dextrorotary (see explanation elsewhere)
- Opposite of vicks compared to water: DL-methamphetamine. Dextrorotary product is almost certainly methamphetamine (or extracted dexedrines?) as its is not worth the trouble to get other dextrorotary precursors or resolve dl-amphetamine…
- Worth Noting: Cathinone and Methcathinone, when dissolved in methanol, will become racemic due to the nature of the molecule (keytone). I’m not sure what other conditions cause this but I am aware that it happens easily, so methcathinone from the black market is almost definitely racemic…
- “Smelling meth on a person”
- Fatigue causes secretion of different chemicals, including ammonia, from the body. Thus you are smelling fatigue, not meth.
- “Made from poison”
- Made from several toxic chemicals; this does not mean it is itself poisonous. For example, drinkable salt water can be made from lye and muriatic acid.
- “Used to cut other drugs”
- Overstated in this role. Usually something much cheaper (and less clean) is used.
- “Meth Oil” ??
- “Speed Bumps”
- Dilute Hydrochloric acid–> This may be purchased at the hardware store. It sold as a brick and driveway cleaner. They call it muriatic acid.
- Sodium Hydroxide–> This, you probably already have. It’s called “lye” at most places; it’s drain cleaner.
- Ethyl Ether–> You’ll probably have to make this. Don’t worry, it’s a breez Just go to your local K-mart or Auto parts store, and get a can of that “STARTING FLUID” it comes in a spray can. It’s used for cold weather starting of gasoline engines.
- “VICKS” nasal inhalers–> USE ONLY VICKS!! No other kind will work that I know of. These are at any drug store or grocery, etc.. You need 12 of em, but don’t buy em’ by the dozen, unless its winter time, then you can just say yer from some nursing home, and you’re stockin up for the patients. Otherwise buy em’ 2 at a time, if possible. Get a friend to help you. The druggists at the drug store usually will know what’s goin on if you buy quantity.
- Two large eyedroppers
- ten small glass bottles
- one large glass or porcelain bowl
- coffee filters
- one small jar with a top
- one Pyrex baking dish
- one glass test tube.
- Break open the inhalers, a pair of real sharp scissors does this good. Place the cottons that were inside in a jar and close the lid. (Remember you use all 12 cottons.)
- In the bowl, combine 1- 1/3 oz. water and 2/3 oz. muriatic acid. Shred cottons in this solution, and knead for 5 minutes with hands. (ALWAYS BE SURE THERE’S CLEAN RUBBER GLOVES on your hands.) You can do it bare-handed if you’ got tough skin. Squeeze all juice out of filters after you knead, and throw em away.
- Filter the remaining liquid into the quart jar. It will be necessary to this several times to get that awful smelling oil out. The chemicals in the inhalers have been bonded to the HCl, and the oils have been filtered off. Throw the filters away.
- Pour enough of the solution into a small bottle to fill it 1/3 full. Save any leftover juice for the second batch.
- Pour 1/4 teaspoon of the lye crystals into the bottle and agitate. Do this carefully, as the mixture will become hot, and give off a gas. Repeat this step until the mixture remains cloudy.
- Fill the bottle from step (5) up the rest of the way with ether. Cap the bottle, and agitate for about 8 minutes. It is very important to expose ever molecule of the free-base to the ether for as long as possible.
- Let the mixture settle. There will be a middle layer that is very thick. Tap the side of the bottle to get this layer as thin as possible.
- Remove the top layer with the eyedropper, being careful not to get any of the middle layer in it. Save the top layer, and throw the rest away.
- Fill a bottle half-way with water, and about 10 drops of acid. Pour the top layer from step (8) into the bottle, and cap it. Shake the bottle for 2 minutes. When it settles, remove the top layer and throw it away. The free base has now been bonded to the HCl/water mixture.
- If there is anything left from step (3), repeat the procedure with it.
- Evaporate the solution in the Pyrex dish on low heat. You can do this on the stove, but I have found that if you leave it on top of a hot-water heater (like the one that supplies hot water to your house) for about 2-3 days, the remaining crystals will be Methamphetamine.
- Dilute HCl – also called Muriatic acid – can be obtained from hardware stores, in the pool section.
- NaOH – also called lye – can be obtained from supermarkets in the “drain cleaner” section. “Red Devil Lye” recommended.
- Ethyl Ether – aka Diethyl Ether – Et-0-Et – can be obtained from engine starting fluid, usually from a large supermarket. Look for one that says “high ethyl ether content”, such as Prestone.
- Desoxyephedrine – can be obtained from “VICKS” nasal inhalers. These are found at any drug store or grocery, etc. They contain 50mg of l-desoxyephedrin e per container. Also known as methamphetamine. 6 containers will give 300mg of l-desoxyephedrine.
- Distilled water – it’s really cheap, so you have no reason to use the nasty stuff from the tap. Do things right.
- a glass eyedropper
- three small glass bottles with lids (approx. 3 oz., but not important)
- one should be marked at 1.5oz, use tape on the outside to mark it (you might want to label it as ether)
- one should be clear (and it can’t be the marked one)
- a Pyrex dish (the meatloaf one is suggested)
- a glass quart jar
- sharp scissors
- clean rubber gloves
- coffee filters
- a measuring cup
- measuring spoons
- Break open the inhalers, a pair of real sharp scissors does this well. Place the cottons that were inside in a bottle (the unmarked one) and close the lid. I use 6 cottons.
- In the Pyrex dish, combine 2/3 oz. water and 1/3 oz. muriatic acid. Shred cottons in this solution, and knead for 5 minutes with your gloves on. Squeeze all juice out of filters after you knead, and discard them. This step bonds the HCl to the meth, forming the HCl salt (what you want). The salt is soluble in water, and thus dissolves.
- Filter the remaining liquid into the quart jar. It will be necessary to this several times to get the awful smelling oils (check the packaging if you are interested in which ones). The chemicals in the inhalers have been bonded to the HCl, and the oils have been filtered off. Discard the filters and clean the Pyrex dish. Remember to wet the filters with distilled water
before you pour, otherwise you’ll lose some product.
- Pour enough of the solution into the clear bottle to fill it 1/3 full. Save any leftover juice for the second batch.
- Pour 1/8 teaspoon of the lye crystals into the bottle and agitate. Do this carefully, as the mixture will become hot, and give off hydrogen gas and/or steam. H2 gas is explosive and lighter than air; avoid any flames as usual. Repeat this step until the mixture remains cloudy. This step neutralizes the HCl in the salt, leaving the insoluble free base (l-desoxyephedrin e) again. Why do we do this? So that we can get rid of any water-soluble impurities. For 3 oz. bottles, this should take only 3 repetitions or so.
- Fill the bottle from step 5 up the rest of the way with ethyl ether. Cap the bottle, and agitate for about 8 minutes. It is very important to expose every molecule of the free-base to the ether for as long as possible. This will cause the free base to dissolve into the ether (it -is- soluble in ether).
- Let the mixture settle. There will be a middle layer that is very thick. Tap the side of the bottle to get this layer as thin as possible. This is why this bottle should be clear.
- Remove the top (ether) layer with the eyedropper, being careful not to get any of the middle layer in it. Place the removed ether layer into a third bottle.
- Add to the third bottle enough water to fill it half-way. and about 5 drops of muriatic acid. Cap it. Shake the bottle for 2 minutes. When it settles, remove the top layer and throw it away. The free base has now been bonded to the HCl again, forming a water soluble salt. This time, we’re getting rid of ether-soluble impurities. Make sure to get rid of all the
ether before going to step 11!
- If there is anything left from step 3, repeat the procedure with it.
- Evaporate the solution in the Pyrex dish on low heat. You can do this on the stove or nuke it in the microwave (be careful of splashing), but I have found that if you leave it on top of a hot-water heater (like the one that supplies hot water to your house) for about 2-3 days, the remaining crystals will be Methamphetamine HCl.If you microwave it, I suggest no more than 5-10s at one time. If it starts “popping”, that means you have too little liquid left to microwave. You can put it under a bright (100W) lamp instead. Microwaving can result in
uneven heating, anyway.
What we mean by hydrochloride is that it has formed a “salt”. The basic structure is unchanged, but an HCl molecule has become attracted to the free base. In this case, the hydrogen from the HCl has become attracted to the nitrogen in the free base.
You will notice that the salt form is much more common. This is for physiological reasons. The same reaction which attracts the free base to HCl could also attract it to other molecules, causing irritation and other symptoms.

Manufacturing methamphetamine, on the other hand, requires the use of not just ether, but reducing agents such as LiAlH4. BAD STUFF! There are other recipes, but none to practical to attempt. Apartment manufacture of meth is not possible.
Reduction of ephedrine with HI is a little better than LAH reduction.
Condensation Product of Phenylacetone and Methylamine
From: [email protected] (Speed Raver)
Assuming you don’t have amphetamine lying around, an easy synthesis with a very high yield is to reduce the condensation product of phenylacetone and methylamine. The benefit of this method is that different amines can be used to produce novel N-alkyl amphetamines (ethamphetamine, tert-butylamphetamine, etc.)
From Ephedrine or Pseudoephedrine
From: [email protected] (Speed Raver)
Making it from ephedrine or pseudoephedrine is possible. The only difference between methamphetamine and (pseudo)ephedrine is that damn alpha-hydroxy group. Reacting your ephedrine with thionyl chloride replaces the OH with Cl to produce N-methyl-alpha-chloroamphetamine as an intermediate. Hydrogenating this product is easy: use lithium aluminum hydride, sodium
borohydride, or even hydrogen gas with nickel or platinum metal as a catalyst. The product of this step is N-methylamphetamine and HCl. Evaporate off the water and you have methamphetamine hydrochloride.
From: [email protected] (Yogi Shan)
Hydrogenation starting with (-) ephedrine, whether direct or via thehalide, will give d-meth. If you start with dl-ephedrine, you get dl-meth.
Reduction With Hydroiodic Acid and Red Phosphorus
From: [email protected] (Lamont Granquist)
From Fester, Secrets of Meth Manufacturing:
Method 4: Reduction With Hydroiodic Acid and Red Phosphorus
In this procedure, the alcohol grouping of ephedrine, pseudoephedrine, or PPA is reduced by boiling one of these compounds in a mixture of hydroiodic acid and red phosphorus. Hydroiodic acid works as a reducing agent because its dissociates at higher temperatures to iodine and hydrogen, which does the reducing. The dissociation is reversible. The equilibrium is shifted in favor
of dissociation by adding red phosphorus to the mixture. The red phosphorus reacts with the iodine to produce PI3, which then further reacts with water to form phosphorus acid and more hydroiodic acid. Since the hydrogen atom of the HI is being absorbed by the ephedrine, the red phosphorus acts as a recycler.
In some reductions, the need for HI is dispensed with just by mixing red phosphorus and iodine crystals in a water solution. The red phosphorus then goes on to make HI by the above mentioned process. With a small amount of due care, this is an excellent alternative to either purchasing, stealing, or making your own pure hydroiodic acid.
This method has the advantage of being easy to do. It was formerly the most popular method of making meth from ephedrine. Now red phosphorus is on the California list of less restricted chemicals, so an increased level of subterfuge is called for to obtain significant amounts. One might think that this is easily gotten around by making your own red phosphorus, but this is a
process I would not want to undertake. Ever hear of phosphorus shells? I would much rather face the danger of exploding champagne bottles. Those who insist on finding out for themselves, will see Journal of the American Chemical Society, volume 68, page 2305. As I recall, the Poor Man’s James Bond also has a formula for making red phosphorus. Those with a knack for scrounging from
industrial sources will profit from knowing that red phosphorus is used in large quantities in the fireworks and matchmaking industries. The striking pad on books of matches is about 50% red phosphorus.
The determined experimenter could obtain a pile of red phosphorus by scraping off the striking pads of matchbooks with a sharp knife. A typical composition of the striking pad is about 40% red phosphorus, along with about 30% antimony sulfide, and lesser amounts of glue, iron oxide, MnO2, and glass powder. I don’t think these contaminants will seriously interfere with the reaction. Naturally, it is a tedious process to get large amounts of red phosphorus by scraping the striking pads off matchbooks.
Another problem with this method is that it can produce a pretty crude product if some simple precautions are not followed. From checking out typical samples of street meth, it seems basic precautions are routinely ignored. I believe that the by-products in the garbage meth are iodoephedrine, and the previously mentioned azirine. If a careful fractional distillation is done,
these products can be removed. They can be avoided in the first place if, when making hydroiodic acid from iodine and red phosphorus, the acid is prepared first, and allowed to come to complete reaction for 20 minutes before adding the ephedrine to it. This will be a hassle for some, because the obvious procedure to follow is to use the water extract of the ephedrine pills to make the HI in. The way around the roadblock here is to just boil off some more of the water from the ephedrine pill extract, and make the acid mixture in fresh pure water. Since the production of HI from iodine and red phosphorus gives off a good deal of heat, it is wise to chill the mixture in ice, and slowly add the iodine crystals to the red phosphorus-water mixture.
To do the reaction, a 1000 ml round bottom flask is filled with 150 grams of ephedrine hydrochloride (or PPA-HCl). The use of the sulfate salt is unacceptable because HI reduces the sulfate ion, so this interferes with the reaction. Also added to the flask are 40 grams of red phosphorus and 340 ml of 47% hydroiodic acid. This same acid and red phosphorus mixture can be prepared
from adding 150 grams of iodine crystals to 150 grams of red phosphorus in 300 ml of water. This should produce the strong hydroiodic acid solution needed. Exactly how strong the acid needs to be, I can’t say . I can tell you that experiments have shown that one molar HI is ineffective at reducing ephedrine to meth. The 47% acid mentioned above is a little over 3.5 molar. I would
think that so long as one is over 3 molar acid, the reaction will work.
With the ingredients mixed together in the flask, a condenser is attached to the flask, and the mixture is boiled for one day. This length of time is needed for best yields and highest octane numbers on the product. While it is cooking, the mixture is quite red and messy looking from the red phosphorus floating around in it.
When one day of boiling under reflux is up, the flask is allowed to cool, then it is diluted with an equal volume of water. Next, the red phosphorus is filtered out. A series of doubled up coffee filters will work to get out all the red phosphorus, but real filter paper is better. The filtered solution should look a golden color. A red color may indicate that all the phosphorus
is not yet out. If so, it is filtered again. The filtered-out phosphorus can be saved for use in the next batch. If filtering does not remove the red color, there may be iodine floating around the solution. It can be removed by adding a few dashes of sodium bisulfate or sodium thiosulfate.
The next step in processing the batch is to neutralize the acid. A strong lye solution is mixed up and added to the batch with shaking until the batch is strongly basic. This brings the meth out as liquid free base floating on top of the water. The strongly basic solution is shaken vigorously to ensure that all the meth has been converted to the free base.
With free base meth now obtained, the next step, as usual, is to form the crystalline hydrochloride salt of meth. To do this, a few hundred mls of toluene is added to the batch, and the meth free base extracted out as usual. If the chemist’s cooking has been careful, the color of the toluene extract will be clear to pale yellow. If this is the case, the product is sufficiently
pure to make nice white crystals just by bubbling dry HCl gas through the toluene extract as described in Chapter 5. If the toluene extract is darker colored, a distillation is called for to get pure meth free base. The procedure for that is also described in Chapter 5. The yield of pure methamphetamine hydrochloride should be from 100 to 110 grams.

All the chemicals were reagent grade, with no special treatment of the tetrahydrofuran (THF), and the atmosphere above the condensed ammonia was not flushed with nitrogen gas.
A three-neck flask was cooled in a dry ice/acetone bath. A condenser was fitted in the center neck, an additional funnel containing l-ephedrine base in THF was fitted into one side neck, and a rubber stopper fitted with a glass tube extending to the bottom of the flask was fitted in the third neck. Anhydrous ammonia gas was condensed and collected in the flask. Small pieces
of lithium metal were rinsed in petroleum ether, patted dry, and added to the condensed ammonia. A deep royal blue color was noted as the lithium metal dissolved in the condensed ammonia.
The l-ephedrine was added drop wise to the lithium ammonia solution over a period of approximately 10 minutes with stirring. When all of the l-ephedrine had been added, ammonium chloride was added slowly to the solution. The flask was removed from the cooling bath, and the condensed ammonia was allowed to warm to room temperature and evaporate from the flask through the side necks.
When most of the ammonia had evaporated, water was added to the remaining solution until it cleared and any remaining lithium metal was decomposed. The remaining solution was removed from the flask to a separatory funnel, where the aqueous layer was discarded. The THF layer was dried with magnesium sulfate, and the hydrochloride salt of the methamphetamine was made by bubbling hydrogen chloride through the THF.
The same procedure was used, substituting phenylproponolamine and methylephedrine as the starting materials. A second synthesis was conducted with l-ephedrine, using the same procedure except that the reaction was not quenched with ammonium chloride.
The reaction was found to reduce l-ephedrine to d-methamphetamine quickly and easily . Furthermore, it was found that the reaction converted phenylpropanolamine to amphetamine and methylephedrine to dimethylamphetamine. The time required for the reaction to proceed from the condensing of the ammonia gas in the reaction flask until the excess lithium was decomposed was
approximately one hour. The majority of this time was spent waiting for the condensed ammonia to evaporate from the reaction flask.
It was also found that the ephedrine would reduce to methamphetamine without the addition of ammonium chloride as a quenching agent.
From: [email protected] (Eleusis)
According to the infamous J.For.Sci. article describing a “novel method of amphetamine production”, the researchers concluded that with or without an ammonium chloride quench yields were good. I like this article especially because the rinky-dink DEA chemists that wrote it didn’t seem to entirely grasp the concept of the procedure they were doing (in fact, a slightly modified Birch reduction known by some other name I can’t recall). All in all, quite an entertaining and educational article ;-).
From: [email protected] (DMurphy3)
This may be so (in fact I read the same article), but typically a water quench leads to the alcohol, which is what we were trying to get rid of to start with. Also, if one were using Na rather than Li (Na is the Birch, I too forget the Li named reduction), adding water to quench will *definitely* be exciting, particularly considering the flammability of THF or ether.
Apparently they were following the guys handwritten notes. It would have been even more interesting had they used the real Birch method, using Na, especially when they tried the water quench ;>)
From: [email protected] (Eleusis)
Yep – apparently that would be the case. As well, any extra Li (or Na if doing the straight Birch method) would convert to the Hydroxide, which might fuck the product up a bit.
I bet you they *did* do that the first time, and then, after they replaced that wing of the lab, they decided not to “publish” those results ;-).
From: [email protected] (Speed Raver)
A surprisingly simple synthesis is possible from the amino acid phenylalanine, which is available at health food stores for about $14 for 100 tablets. Phenylalanine is 2-amino-3-phenylpropanoic acid, which is more or less amphetamine with a COOH where the CH3 should be at the end of the chain. Thionyl chloride will replace the OH with a Cl, which falls off and is
replaced by H when you give it lithium aluminum hydride, sodium borohydride, or hydrogen gas and nickel/platinum. If you use hydrogen and metal for that step, you’ll ha v e to reduce the carbonyl group with one of the hydrides, so best save time + effort and use them and do both reductions at once. When that carbonyl is reduced, you now have amphetamine. Go back up to that first one I mentioned for upgrading amphetamine into methamphetamine.
These are methods that are subjectively evaluated to be less useful, but still may serve as interesting lessons in applied chemistry.
Synthesis from Amphetamine
From: [email protected] (Speed Raver)
One of the easiest ways to make methamphetamine is from amphetamine. Of course, this assumes you have amphetamine in the first place, but let’s just pretend you have some and you want to spice it up a bit. The difference between amphetamine and methamphetamine is the addition of a single methyl group (CH3) to the amino group sticking off the middle carbon atom in the chain. Fortunately, substituting amines is really simple. Vaporize your amine (your amphetamine) with a bunch of vaporized chloromethane (CH3Cl, a solvent) and some gaseous pyridine… voila, the amino group takes the methyl from the chloromethane and lets a hydrogen go. The hydrogen joins the liberated chlorine, and the resulting HCl is soaked up by the pyridine. The pyridine is optional. Adding it drives the reaction a bit by pulling the excess HCl out of the equation, but it’s not necessary.

Does the P2P method [reductive amination] ever end up attaching TWO chains to the same methylamine, producing a crazy looking monster with two “wings”
This last question is solved be reference to a principle called the law of mass action. An excess of methylamine will inhibit the secondary reactions.
Typically, a reductive amination done in a parr bomb or using sodium cyanoborohydride is done with a five times molar excess of methylamine (or methylamine hydrochloride.)

Let me know how bromobenzene + acetone + NaOH turns out. I’m interested in this since I haven’t seen it anywhere else (unlike some people, I don’t have the Abstracts in my closet 🙂
Make sure to use an EXCESS of acetone, because 1 its more readily available and 2 it will prevent any diphenyl/triphenyl/xphenyl acetone from forming.
Hell, if your making straight amphetamine, you could even just go with acetone as the solvent too, if you could come up with a good way to separate the 2-aminopropane you’d make with the amphetamine. Given that this gunk has a bp of 33 or 34 degrees at standard pressure, it shouldn’t be too hard. Smells like ammonia though… maybe you should “catch” it in HCl water when you
As with any distillation there will be some left over. Never fear, 2aminopropane (or “isopropylamine”) is water MISCIBLE. Yes, the BASE form is miscible w/ H2O! Amphetamine BASE is only “slightly” soluble in water, so if your really a purist you can dissolve your “mostly amphetamine some 2aminopropane” in ether and backwash with water maybe ONCE. Then precipitate the crystals with dry HCl or H2SO4?
Question is, how much ammonia and reducing agent are you willing to waste on making 2aminopropane?
Purification by Crystallization
From: [email protected] (Sean Casey)
For a purification by crystallization of any of the HCL salts of ephedrine and related illegals, I’d suggest a two solvent system with methanol and methylethylketone. This tends to occlude a slight amount of solvent so keep your crystal size small and grind and dry the result. Both these solvents are easily available if you know where to look.
I wouldn’t suggest ethanol or acetone as they tend to easily collect H2O; this can happen unexpectedly and when it does, their solvency power will greatly increase, redissolving your crystals. Be careful as methanol is toxic; don’t get it on you or breathe the fumes.
Read a lab handbook about two-solvent purification by crystallization. Fascinating stuff.
Very scientifically unsound, but interesting nonetheless.
An average wrap of speed contains less than 10% Amphetamines, (often as low as 2%) and over 90% of adulterants.
From: [email protected] (Jason Kennerly)
Methamphetamine in its pure hydrochloride salt form is colorless. However, products on the market today are often not colorless. The following is a table of some common impurities and the colors associated with them. Note: There is no doubt a segment of the dealers who will add food coloring or some other such color to their drug to make it more appealing, with the philosophy that a brightly-colored product may sell better than an off color product. This is relatively uncommon however.
Sometimes “speed” is present as waxy rocks that almost seem wet, but do not dry out properly. I am not sure what the cause of this is, but its most likely some form of oil, either formed in the reaction or left over from a very poor solvent. It may or may not be harmless depending upon what it is. This oil is often removed with acetone, but ethyl-ether would be better suited for this as it dries faster.
Pure methamphetamine HCl melts at around 170c (338f ). The crystals can be carefully chopped and mixed with sodium carbonate, and when the resulting powder is heated (and the methamphetamine HCl melts) CO2 and methamphetamine base vapor is given off. This is probably one of the more effective ways of smoking meth if you are careful, however the hydrochloride salt is often the form smoked as the base form is often an oil and is difficult to store, transport, and work with. Smoking the HCl form is OK if you don’t mind a small quantity of pyrolysed drug.
d-methamphetamine is, by nature, optically active. l-methamphetamine is also optically active, but in the “opposite” direction. You can test methamphetamine HCl for optical activity with the greyish-clear plastic pieces from a pocket video game. Dissolve the methamphetamine in distilled water, then place one of the optical filters (the grayish clear things from the games LCD display) in front, and one in behind of the solution. Rotate one filter, and note the angle that is brightest and the angle that is darkest. If many “swirlies” appear, either use a different vessel to hold the solution in, or make sure the solution is well stirred. After you have done this, repeat the procedure with distilled water. A handy thing to use as a “calibration” of
sorts is to extract the l-desoxyephedrine from a Vicks Inhaler (which is l-methamphetamine), and run this test on it as well.
The EPHEDRINE/CAT TEST
Its probably not too uncommon that some guy screws up a synthesis, but by some chance gets a partial yield. Or a dealer uses Ephedrine as cut. The problem with Ephedrine (far more so than
pseudephedrine) is its beta-agonist properties – it raises blood pressure and pulse far more per “unit of high” than methamphetamine.
It is advisable to become familiar with the many ways of synthesizing methcathinone from (pseudo)ephedrine, as just such a procedure can be used on freshly produced methamphetamine to verify that the (pseudo)ephedrine was in fact reduced.
The smell of basic methcathinone has been reported to resemble that of “pistachio ice cream”. Suffice to say that it is sweet, pleasant, and to a cat-head, nirvana. You should become familiar with this as well, in order to be able to know if suspected methamphetamine is in fact actually methcathinone.
The “BURN TEST” [residue test]
Methamphetamine HCl is heated on a piece of foil over a flame. It should first melt (at over 170c) then begin to fume. Often the fumes will ignite. All amphetamines will pass this test that I am aware off, including the over-the-counter l-isomer present in vicks inhalers (the *only* way to check this is to check optical activity , either by resolution or by actually measuring it with optical filters). Methcathinone HCl has a higher melting point than methamphetamine HCl (like over 190c at least) and a characteristic smell, giving it away in an instant. Residue left behind may be by-product or “cut”, there’s no good way to tell which… Suffice to say that if there is more than a very small amount left afterwards, there is either cut or by-products present.
The TASTE TEST [illegal without prescription snicker snicker]
Methamphetamine has a very bitter taste. Amphetamine has a bitter taste, followed by some degree of numbness. This isn’t the most useful test in the world, especially considering it relies upon subjective senses too much IMHO, but it may help discern the product. Methamphetamine is also more active on serotonin that amphetamine according to net resources.

Sometimes ‘speed’ is present as waxy rocks that almost seem wet, but do not dry out properly. I am not sure what the cause of this is, but its most likely some form of oil, either formed in the reaction or left over from a very poor solvent. It may or may not be harmless depending upon what it is.
It is more than likely the “didesoxyephedrine” referred to by Emde, a product of the coupling of two radicals of the reduced ephedrine or pseudoephedrine. It appears to some extent in almost all syntheses relying on reduction and typically appears at the very end of the process of forming the HCl salt by bubbling HCl through the mixture. And no, I haven’t forgotten my promise to post this paper. The scans just sucked when I tried to scan as text (5 pages magically became 10-15 of scrambled text). I am currently trying gif type scans. The *oil* may be removed, as you stated, by washing with ether. However, it will never dry out as completely one might suspect. Even drying under heavy vacuum leads to only a temporary solution. Once it is exposed to air it quickly becomes an oil again. Often this is a brown color as you stated for other by-products. As far as the rest of the post, I find it very useful and agree with it completely.

Written and tested by: The Leftist.
What to do with it once you have made it.
Take a ball about the size of a lead pellet, and wrap it in tissue, and swallow, or you can put it in capsules and use it. You can smoke it, mix it with vitamin B-12, and snort it like cocaine. You can also sell it, for about $65-70.00 a gram, and don’t forget to cut it. Remember, this is pure stuff!!

PLEASE! DON’T SMOKE IN THE SAME ROOM WHEN YOU DO THIS. OPEN A WINDOW IN THE ROOM IF POSSIBLE. FOLLOW THESE INSTRUCTIONS EXACTLY. THIS RECIPE HAS BEEN TESTED AND THIS IS T BEST WAY TO DO IT. DON’T TAKE SHORTCUTS, AND DON’T EVEN START TO DO THIS UNLESS YOU HAVE ABOUT 3 HOURS SPARE.
(DO THIS FIRST)
Take one of the small bottles and spray starter fluid in it till it looks half-full. Then fill the rest of the way with water, cap the bottle and shake for 5 minutes. Then, draw off the top layer with the eyedropper, and throw away the water layer. Repeat this until you have about 3 oz. of ether. Put the cap on it, and put it in the refrigerator if you can. (If you can’t, don worry about it) You’ll use this in the procedure below.
THE TRIED AND TRUE HOME PRODUCTION METHOD
Police are now calling this the “New Cocaine”.
It is very easy to become delirious off the ether fumes, so be sure you are well ventilated, I mean it!!!
Small, aspirin, or experiment bottles seem to work the best for smaller batches. The measurements are not exact, so you don’t have to be either.
In step 9, be sure you don’t use too much water. Remember, this is the water you have to use to evaporate.

(WARNING!) This recipe is bogus! YOU WILL NOT HAVE METHAMPHETAMINE! You have simple extracted pseudoephedrine! All this stuff will give you is
There are better recipes out there but if you cant get your hands on sodium borohydride and a reflux condenser then don’t even mess with this recipe!
But the ETHER extraction method is as true today as it was then!

One, from Phrack magazine, is the “tried and true method” for prepping meth from Vick’s nasal inhalers. Vick’s nasal inhalers contain “l-desoxyephedrine,” another name for “l-methamphetamine.” The l- isomer of methamphetamine is the relatively inactive one, usable as a (mild) nasal decongestant. The d- isomer is the one that every one wants and that Uncle Sam has declared is just too cool for any one except doctors.
The procedure described would extract the l-meth from the inhalers and collect it and that’s it. I’m sorry, but the Isomer Fairy can’t wave her magick wand and reverse the chirality of the molecule. The only way to change between the two isomers is to oxidize the l-meth into phenylacetone, condense it with methylamine, then reduce it. Sorry, but soaking inhalers in HCl then
separating the “juice” with Et2OH just won’t do it. You’ll get l-meth and that’s that.
The same recipe (for extraction of l-isomer), reformulated:

Preparing Ethyl Ether
WARNINGS: Ethyl Ether is very flammable and is heavier than air. Do not use ethyl ether near flame or non-sparkless motors. It is also an anaesthetic and can cause respiratory collapse if you inhale too much.
Take the unmarked small bottle and spray starter fluid in it until it looks half-full. Then fill the rest of the way with water, cap the bottle and shake for 5 minutes. Let it sit for a minute or two, and tap the side to try and separate the clear upper layer. Then, draw off the top (ether) layer with the eyedropper, and throw away the lower (water) and cloudy layer. Place the ether
in the marked container. Repeat this until you have about 1.5 oz. of ether. Put the cap on it, and put it in the freezer if you can. Rinse the other bottle and let it stand.
Ethyl ether is very pungent. Even a small evaporated amount is quite noticeable.

A more credible sounding one mentions that “methamphetamine is prepared by the calalytic reduction of pseudoephedrine in acetic acid” blahblahblah and then goes on to describe, not catalytic reduction via acetic acid, but reduction with sodium borohydride. I’m sorry to say that no method attempting to directly reduce (pseudo)ephedrine’s hydroxyl group is going to work. You can’t expose it to a strong acid, or a weak acid, or sodium borohydride, or even lithium aluminum hydride and expect it to reduce at all. As with the Vick’s Inhalers “recipe,” you get a lot of SOMETHING, but it ain’t d-meth. All you’ll be left with is your (pseudo)ephedrine and a bunch of acid, lithium, and/or sodium and lotsa hydrogen gas. This is because the hydroxyl group (the OH in ephedrine) is on a very acidic carbon (the first carbon away from the ring) and a hydroxyl group is very basic. If the hydroxyl were on the second carbon from the ring (the carbon with the amine group, the NH2 or NHCH3), there might be some chance, but it’s not and there’s not. You’re not getting a basic group off an acidic carbon without a fight, and acids, borohydride, and
LiAlhydride aren’t gonna fight that hard.

Your post was interesting, but this is not quite true. Direct hydrogenation over Pd or Pd on a carrier is well known and facile. You add a little perchloric, phosphoric or sulphuric acid, which esterifies the-OH group that you’re complaining about.
Thus making the intermediate halide via SOCl2, like you mentioned, is unnecessary.
