That appears to be the case, though hydrocodone and oxycodone also are biotransformed into stronger drugs and the gluconrides thereof as well, but seem to have enough intrinsic activity to make snorting them somewhat worthwhile . . . not as much as snorting hydromorphone or oxymorphone, of course . . .
100x Snorted heroin @FutureReference?
Future says it loves the mucous membranes, that’s good enough for me lol. What would you say its resemblance is closest to? E.g a supercharged snorted Oxycodone or something else entirely?
