I just cannot get the hang of using a torch, I always seem to waste some gear from the excess of heat.
I am, however, a good smoker with an ordinary bic, I get many many tokes out of a small amount of gear....and as primarily an IV user, I feel I can gauge how much I am getting/wasting via smoking....i.e., IV has 100% bioavailability and smoking has 90-ish% bioavailability (I think), so if the high from a certain amount of gear smoked is similar to that same amount of gear IV'd, then I have a reasonable idea that I haven't wasted much.
I still remember a horrible incident where I had a pipe, my last point of gear and only a torch lighter....and most of the gear went up in smoke (not in a good way).....sigh.
If anyone has any tips for using torch lighters with a glass pipe I'd love to hear them.
