Psychoactive drugs operate by temporarily affecting a person's neurochemistry , which in turn causes changes in a person's mood, cognition ...
Stimulants improve focus and alertness. Low (therapeutic) doses of dopaminergic stimulants (e.g., reuptake inhibitors and releasing agents) also promote mental and athletic performance, as cognitive enhancers and ergogenic aids respectively, by improving muscle strength and endurance while decreasing reaction time and fatigue.
