This effect can initiate a cycle of abusing Adderall that eventually results in full-blown physiological dependence. To continue achieving this effect, the amount of medication used must be increased over time as the brain adjusts to the drug’s presence and reduces its response accordingly (tolerance). When used in a way other than as directed, Adderall can rapidly increase the amount of dopamine in the brain and produce feelings of euphoria. Like many psychoactive drugs, Adderall can be misused and become addictive. When stimulants are introduced into the body, they increase the amount of dopamine, but they also impair the body’s ability to make its own dopamine after extended use and can cause many side effects. Individuals with ADHD use the medication daily on a fixed therapeutic regimen, and it induces a calming effect, allowing them to concentrate on tasks at hand.īecause it is a stimulant such as meth or cocaine, Adderall boosts dopamine in the brain, a neurotransmitter associated with pleasure, reward and attention. It is commonly used to treat attention-deficit hyperactivity disorder (ADHD), a condition in which people find it difficult to focus on a single task and may act impulsively.
