When used with regard to recreational drug use, afterglow refers to positive physical and mental effects that linger after the main effects of a drug have subsided, or after the peak experience has subsided. This state is often characterized by feelings of detachment or increased psychological clarity. The term is most commonly associated with hallucinogens, particularly tryptamines, and dissociatives. This phenomenon contrasts with hangovers, a condition that follows the use of various substances, including alcohol.
