From "Queen's Gambit"(tho there's no actual drug dealers in the tv show, not sure abt the book it's adapted from, tho):
Girls Orphanage, it's set in the 1950s/1960s n they give pills(drugs) to keep the girls calm a good part of the time. The protagonist learns to palm(under tongue) each pill n take a few at a time to increase the rush, then she steals/breaks into the pharmacy to steal the giant jar of pills-i forgot wat happened next cos this show is about chess, dammit n how good of a player she is!
