Always did IV with crank/meth, smoking the stuff couldn't hold a candle to IV, As much as I tried smoking never delivered what I wanted. I think you should get more duration from snorting, oral is also a great way to take amphetamines, if you've got great glass purity wise then any ROA should be fun (even though smoking for ME was never any good, I just never gave it a chance to be perfectly honest). Smoking pure crack (purified coke using ammonia method) now that certainly worked for me - if crack heads got that shit instead of that ghetto bi-carb crud they'd feel like it was their first time, lol if only they knew (yeah that would really help society SKR, get a grip, and let em have their 2% purity).
