i've done fentanyl several times and in my experience this was some of the best i've had. my friend did just the smallest bump i think you could ever make (and he has a tolerance to opiates, does opanas all the time) and it totally fucking wasted him. didn't know where he was at, etc. then he start to puke up a little black shit and we were like oh shit we need to get him to the hospital or go get some narcanon from the pharmacy but then all of a sudden he start coming around just fine. he ate something and was good to good. however, be careful with this shit, you need to know what you're doing or you can easily die from an OD.
Would you do bumps of LSD powder? The fuck are you guys huffing on the side? Gasoline?
