What are the possible consequences of stimulant misuse?

As with other drugs in the stimulant category, such as cocaine, it is possible for people to become dependent on or addicted to prescription stimulants. Withdrawal symptoms associated with discontinuing stimulant use include fatigue, depression, and disturbed sleep patterns. Repeated misuse of some stimulants (sometimes within a short period) can lead to feelings of hostility or paranoia, or even psychosis. Further, taking high doses of a stimulant may result in dangerously high body temperature and an irregular heartbeat. There is also the potential for cardiovascular failure or seizures.

Stimulants’ Effects on the Brain & Body

Q: How do stimulants affect the brain and body?

Stimulants, such as dextroamphetamine (Dexedrine, Adderall) and methylphenidate (Ritalin, Concerta), act in the brain on the family of monoamine neurotransmitter systems, which include norepinephrine and dopamine. Stimulants enhance the effects of these chemicals. An increase in dopamine signaling from nonmedical use of stimulants can induce a feeling of euphoria, and these medications’ effects on norepinephrine increase blood pressure and heart rate, constrict blood vessels, increase blood glucose, and open up breathing passages.
