*shrug* I dunno, I havnt tried Fioicet(whats that?) or heroin..
Well I have only had heroin one time ever in my life, and i only snorted it and I took tiny bits coz i didnt know how much made OD, also i live in NZ so it probably wasnt even proper heroin, homebake probablly, or heroin cut to shit with fuck knows what they cut heroin with....so doesnt really count.
