The person in the group (who is either sober or (more rarely) uses the drug so much it hardly affects them) who watches over the others who may be under the effects of drugs, usually hallucinogens like shrooms or acid. Their job is to watch over everyone and make sure theyâre safe. Most of the time, their job is to keep you from having a bad trip (panic attacks and stuff) and maybe acting rash.
âJust bagged some shrooms, who wants to be ground control?â
