I also have never understood why dealers were mixing it with heroin. I've done both and am sure you could sell fen. On it's own.The rush from Fent is real strong but doesn't last long.Junkies love that rush you get when you shoot so I'm sure they would buy it.
Ive seen Fent.busts on the news in Detroit but I did dope for years and never got Fent and never heard of anybody who had It but I didn't buy in open markets only from people I knew.
It's always a choice to do any drugs and it's bullshit to say that you CAN'T stop.I don't do it anymore but my back is fucked up and I'm in constant pain but that's all just an excuse to be a junkie I choose not to anymore
