I always get the best crack, I live in the cocaine capital of the US which is south FL... always bomb ass shit here, and yes, OP there are fake slabs/rocks out there, we call them "dummy rocks" here, its basically identical to what crack looks like, smokes like, and everything.. but it doesn't have the feeling, taste, or smell, of good real rock.. I have only been given this garbage 2 times, and I went off on my plug that gave it to me! I told him, he had to refund me, and he gave me fake shit and would spend thousands of dollars with this guy, between me and my friends.. and the 2 times he sold me that, apparently he didn't even know, because he got ripped off, I believe him too, because, he didn't smoke the shit, just sold it and was a straight ass connect, never tried me, and always gave me the best shit.. and he was straight enough to refund me as soon as he got back on point with the good shit he normally had! both times.. depending on who you got this shit from, I would call them out and tell them it was fake and ask for your money or some real shit back, or just not fuck with them anymore if they wont do that, that is just bad business! if you smoked crack, out of a stem with chore boy, and got NOTHING! you no doubt got robbed.. was this someone you call/go to a lot? or some random corner boy? PS Smoking crack of of foil, is a no no! that shit is such a waste! I did this once, when I had some of the best rock you could ever get, and wasted 3/4 of my shit, trying to get a hit.. before I finally had to borrow $3 to go get a pipe.. I was so pissed.. its not like smoking heroin, where you can chase the smoke perfectly, it burns way too fast, and doesn't run on foil, so you cant catch even 1/8 of the smoke your trying to inhale and all I got was numbed lips, and a fucking tease... never smoke it of foil!
