The Short-Term Effects of Amphetamines

If you are a user of amphetamines, you probably have a very narrow focus on the short-term effects of amphetamines. You likely think first of the ways that they increase focus, elevate your energy, and improve your mood. To some extent these are all true. Although, it is worth noting that these effects are more likely to be safe, consistent, and manageable if you are using a prescription amphetamine intended for your use and prescribed by a doctor.

Part of addiction is denial and it is probable that you are operating with some level of it in order to ignore many of the other short-term effects, a lot of which aren’t that pleasant and a few of which can be dangerous. You need to pay attention to all of your symptoms and be honest about your drug use.

It is also important to recognize the different factors that determine which effects will manifest. You won’t automatically experience every symptom. You will only get a range of them depending upon these factors. And, over time, those may change as well.

If you are experiencing trouble with limiting your amphetamine intake and you believe it is part of an addiction pattern, you need to be less concerned with side effects and more concerned about treatment. can help you find a rehab program that meets your needs.

Short-Term Effects

Short-Term Effects

Dry mouth and nausea are potential short-term effects of amphetamines.

Remember: there are many possible short-terms effects and, again, various factors will contribute to which ones you personally experience. The Center for Substance Abuse Research identifies the following:

  • Fever
  • Heart failure
  • Aggression or paranoia
  • Slower, faster, or irregular heart rate/heart beat
  • Increased blood pressure
  • Increased movement/verbosity
  • Euphoria
  • Increased sense of well-being
  • Lessened fatigue/drowsiness
  • Lessened appetite
  • Dry mouth
  • Dilated pupils
  • Faster breathing
  • Increased alertness/liveliness
  • Nausea
  • Headache
  • Changed sexual behavior
  • Twitching of small muscles
  • Absence of social inhibitions
  • Delusions of grandeur

If you are feeling these effects as part of an addiction cycle, be aware that you will develop a tolerance and the high associated with amphetamines will diminish over time. You will need the drugs to feel normal and the sensation of euphoria will be limited, if not absent. You will have to use more amphetamine to achieve a high and this will put you at risk of overdose.

You need to eliminate all recreational use and if you can’t, you need to seek treatment.


The amount that you take will obviously have an impact on the type and severity of the symptoms that you experience. Generally, the larger the dose or impact of the drug, the larger the side effect.

If you take to high of an amphetamine dose, you will overwhelm your nervous system. This flood of dopamine can trigger severe symptoms. In a study focused on amphetamine psychosis, dosage was held partially accountable for the manifestation of symptoms.

The Drug

The amphetamine you choose to take will impact which symptoms you experience and the severity of them. For example, a small dose of Adderall will impact you less that an equal amount of crystal meth.

If you choose to add other drugs and/or alcohol to the mix, your symptoms will be more acute and generally have a faster onset.


The Duration

If you are developing tolerance, you may use amphetamines more frequently than you did initially. This will cause the effects to stack up as you attempt to avoid withdrawal. This stacking will worsen the negative side effects of the amphetamine.

Stress Level

If you are highly stressed, your nervous system is flooded with stimulatory chemicals, which make you aroused. Adding a stimulant to those stress hormones is like throwing gas on a raging fire. This shock to your system can trigger some of the worst side effects.

Sleep Deprivation

If you are using regularly, you aren’t sleeping normally. Your brain function will be suffering because of this lack of adequate rest. After one night of no sleep, dopamine increases to try to keep you alert. If you trigger more dopamine with amphetamine use, you increase the likelihood that dangerous side effects will occur.
