Hard is often crack, indeed. He said hard and I asked like a primo? Coke? He was like, "something like that. they call it molly usually, some call it flokka, sometimes it's good sometimes it's shit." What I gathered is people preferred it when it smelled like formaldehyde, get that shit wet, they say....
It definitely had that numbing effect like crack. Shit also gave me mild mouth sores and a sore throat and like feeling faint like I'm going drop like a bag of bricks.
Never intentionally smoked embalming fluid but I recall the very distinct smell from funerals.
