Speed Energy: Cardiovascular and Neurochemical Effects of Stimulants, Risks, and Evidence-Based Harm Reduction
“Speed” is a colloquial term commonly used for amphetamine-type stimulants, which rapidly increase alertness and perceived energy through effects on central neurotransmission. Clinically, these drugs act primarily by enhancing synaptic concentrations of monoamines—especially dopamine, norepinephrine, and to a lesser extent serotonin—by promoting release and inhibiting reuptake. The result is heightened sympathetic nervous system activity, improved… Read More »
