Sorry but I have no advice for this, I used to try to help out non-users but most non-users who claim to hate drugs never will like them, they are too damn brain washed by gay groups like D.A.R.E. and other anti-drug groups. I tried to open up so many peoples eyes and they warn me off in digust. I just fuckin' hate non-users who dont even try to open up to what I try to school them on so....no I have no advice for you to give to your friend lol.
