Yeah it's hard to tell. I have no experience with heroin, I bought something that was supposed to be heroin once while in the service but I just added it to hash and smoked it, Wasn't impressed. I once bought some shit that was supposed to be coke and snorting it only produced a downer effect. I was disappointed with it to so I put the last of that in a bowl with some hash and WOW it was fucking great. Strange but cool. I realized later, once I returned to the US and PCP hit the scene that is exactly what I was sold as coke. Too bad because I could have had much more fun with it if I knew it was smokable at the start and produced such an interesting high.
