Marijuana is a plant that contains THC, a psychoactive chemical that causes mind-altering effects. Those who consume marijuana are typically referred to as marijuana smokers, but there are various other synonyms to describe these individuals. Some common synonyms for marijuana smoker include pot head, stoner, cannabis enthusiast, weed smoker, herb aficionado, 420 enthusiast, ganja lover, and Mary Jane connoisseur. Although these terms can be used interchangeably, some are considered more respectable and politically correct than others.
