i don't know if it's been discussed but mdpv is very active smoking like on tobacco no need for a crack pipe. i've just discovered this the hard way and am now fiending. i'm glad i'm giving everything in my posession to a more responsible friend for safe keeping...this stuff is too cheap and too addictive..
lol, I'll stick to the crack-pipe as I don't wanna have to smoke like 10 cartons a day just get a good session of MDPV in.. :D
