I've done it quite a few times, but like quite a few others out there probably only because I have somewhat of a needle fetish. I just want to shoot SOMETHING up. I have a scale and I know exactly how pure the product is. Maybe it's because I'm small (98-104lbs) or the cocaine is just very pure, which it is, but most of the times I've done it I just get scared. Like I'm going to have a heart attack. No rush, really, but I do get that feeling of pressure/noise in my ears. Does anyone have any thoughts? Similar experiences? Oh, and I'm new, so I'm sorry if I slipped up.
