It is very very horrible to try to smoke heroin like crack. It is far more sensitive to heat. You are destroying a pretty decent amount.
I find it's hitting me up a lot on the wire wool pipe tbh, i'm getting dark brown powder.
also even if i am wasting some i'm not even that fussed, if i really was to care so much about losing a bit of smack then i'd just become a needle junkie but losing a bit of gear is MINOR to mei find the pipe more fun and easy to carry around and use in toilets etc.
