the "last show" phish threw in vt,there was a rave tent someone erected..i was inside,this guy come up and said "want some liquid coke"..being a novelty i said sure..he handed me a bottle with the rx sticker on it.then ran off!..i did a few "snorts" and put it in my pocket..never got much off it since,of course,i was spun on L..he bounced up later and asked for it back..i happily thanked him and returned it..my only other knowledge is its used for nasal surgery and micro surgery,constricts the blood vessels so you dont bleed and gag while under the knife
