I've always thought of vaporizing as the act of extracting and inhaling the hash oil out of buds in one simple step. Have any 'studies' been done on the thc content of vapor. I've been reading a lot lately of the high thc contents of oils, waxes, budders-like 60-80% thc...now I'm just wondering what the percentage would be of the vapor of average buds-say 15% thc content. Leaving all the plant matter behind, certainly the percentage would be much higher than 15% in the vapor. Would it be as high as the content of unsmoked/vaporized oils?
