The first time I smoked DMT out of a light bulb I got very poor results. I could never get the crystals to vaporize. I would just put it in between a small bowl of herb and make sure to lightly, light the herb on top and not torch it at all. That's how I used to smoke JWH with marshmallow leaf out of my bong and it worked wonders. Way better then chasing the dragon on tin foil. I just like that method because as long as you inhale all the smoke from the mixture your pretty much guaranteed to inhale at lest SOME the combustible product. Also i've had a friend who had bought some DMT and smoked it that way and said it worked wonders.
