get a weed grinder, collect all the crtstals, have nice big bong out of that, thatll fuck you over..... but thats alot of time and effort, my advise is to just get a different kind of weed, most people find that changing the type of weed you smoke (or even substance, pollen is GREAT), starts ther tolerance up again.... it doesnt make sense but it works. Drink alcohol whilst you smoke that makes a difference to how fucked you get.
