Jesus, when will you kids realise resin is the purest smoke? all the little crystal balls on the plant- that's resin, which becomes hashish when pressed together into a solid mass.
If your talking about the shit that collects in your pipe, that's tar if your smoking your weed, and distilled resin if your vaping your weed.
Smoking hash/resin is so much more potent than any weed. On weed the resin is spread out over the bud, in hash it's just resin without the weed.
Smoking weed is bad for your lungs and will make you weak in the head, smoke hash like the folk out east have done for thousands of years- they must have a reson for just taking hash and not smoking weed(i exclude thailand as them buggers will smoke and eat anything).
