A stimulant is a psychoactive drug that operates by blocking the reuptake of dopamine, norepinephrine, and serotonin in the synapses of the CNS. The American Society of Addiction Medicine (ASAM) defines addiction as a disease affecting brain chemistry and circuitry, which then leads to compulsive drug-seeking and using behaviors.
