I remember my ex-girlfriend getting into drugs when we kind of split apart (cause of my mental health deteriorating at the time). I met her at a house party (drink only) the next year and she was going on about how she got so into drugs at one point that she was doing them pretty much every night and waking up in random strangers' houses without remembering how she'd gotten there. Fuck that. I imagine she was always quite eager to leave after waking up.
