Introduction and Definition Amphetamines constitute a powerful class of synthetic psychoactive substances recognized primarily as central nervous system (CNS) stimulants. Chemically, they belong to the phenethylamine group, sharing structural similarities with the naturally occurring monoamine neurotransmitters, specifically dopamine and norepinephrine (noradrenaline). Functionally, these compounds operate by encouraging the release and inhibiting the reuptake of these […]
