I can't think of one for weed per say, but when i was in grade 6 me and my friend decided we wanted to see what snorting coke felt like, so we took some hard candy calledunk rocks ( I think) and crushed them up into powder and then snorted it, omfg did that hurt the nasal passage! and go figure that same friend is now a big time Coke head! For me I think it scared me on some level from snorting cocaine lol
