I don't know anything about vaporizing and hash but i have used a vaporizer with weed on occasion and was baked out of my gourd for more hours than I can remember. Used to make a tea out of hash when I lived in Europe, since that's all we could get that was quality (also smoked it in divers manners, ate it, etc.) I really loved it as tea though. Long drawn out high with magnificent peaks and troughs, waves, ripples, hurricanes and dead calms, one after the other and sometimes, seemingly, all at once -- although I might have just been stoned!
