Illicit drugs are substances whose non-medical use is prohibited under international drug control conventions and global drug control laws due to their significant potential for dependency and abuse. These substances pose substantial risks to individual health and societal well-being. Recreational drugs, on the other hand, refer to psychoactive substances consumed without medical supervision, primarily to alter consciousness for purposes of pleasure or relaxation. Users often mistakenly assume that infrequent or sporadic consumption of these substances is non-addictive despite evidence to the contrary. Recreational drugs can encompass both legal and illegal substances, with their primary use aimed at achieving an elevated or altered state of consciousness for non-medical reasons.
