Unconscious, not yet there isn't, but after toking (absolutely NO tobacco!) for 40 years, my lungs were a mess! Constant coughing, gluppy lungs, I won't even talk about mornings. Two weeks after getting a Vapor Brothers, my lungs were clear- no morning cough. I have almost stopped smoking in favor of vaping. I do still prefer the "smoking" high for late evening toking. I am willing to bet that, maybe 10 years down the road, you'll own a vaporizer. Mine was worth every penny! My two adult sons are straight and hate the smell of pot. Getting the vape has calmed things down quite a bit. They don't gripe half as much about their pot smokin' Mama. WV, get a vaporizer. It doesn't have to be a Volcano- the little "box" units are quite acceptable and cost 1/3 as much. I got mine for under $150 including S&H. - Granny:stoned:
