Cannabis smoke condensate III: The cannabinoid content of vaporised Cannabis sativa
Cannabis sativa is a well-known recreational drug and, as such, a controlled substance of which possession and use are illegal in most countries of the world. Due to the legal constraints on the possession and use of C. sativa, relatively little research on the medicinal qualities of this plant has been conducted. Interest in the medicinal uses of this plant has, however, increased in the last decades. The methods of administration for medicinal purposes are mainly through oral ingestion, smoking, and nowadays also inhalation through vaporization. During this study the commercially available Volcano vaporizing device was compared with cannabis cigarette smoke. The cannabis smoke and vapor (obtained at different temperatures) were quantitatively analyzed by high-performance liquid chromatography (HPLC). In addition, different quantities of cannabis material were also tested with the vaporizer. The cannabinoids:by-products ratio in the vapor obtained at 200°C and 230°C was significantly higher than in the cigarette smoke. The worst ratio of cannabinoids:by-products was obtained from the vaporized cannabis sample at 170°C.
Smoking cannabis provides more by-products (e.g. carcinogens, tar) than vaporization.
Experiments show that vaporization at 230° C provides the highest THC:by-product ratio.
Loading more cannabis in your vaporizer actually leads to less THC by weight.
The HerbalAire is better than the Volicano and is half the pirce and it is made in Canada.
im gonna try less bud next time too…. 230 C seems kind of high to me…. but ill try it…. you know what…. im gonna hafta put it at 420F !!!!! lol ive also noticed that cooking things in the oven at 420 always makes them taste much better….. unless its the weed
This is great to hear. I had always “heard” that Vaping was better for you but was wondering how much THC was being ingested compared to smoking. Now I know.
I did hear a rumor which I am skeptical about. It was that Vaping releases a higher content of nitrogen than smoking. The person spreading this rumor also tried to convince me that excessive nitrogen is bad for you. In the amounts that we are talking I feel that there is no risk. I cannot find any data. Does anyone have any more definitive information?
Air is 78.08 % Nitrogen. Don’t really think Nirtogen will bother you much.
Vape away.
guess i’ll be putting less bud in the vaporizer.
