Marijuana Vaporization Study

edited July 2010 in Man Cave
A central tenet underlying the use of botanical remedies is that herbs contain many active ingredients. Primary active ingredients may be enhanced by secondary compounds, which act in beneficial synergy. Other herbal constituents may mitigate the side effects of dominant active ingredients. We reviewed the literature concerning medical cannabis and its primary active ingredient, ∆9-tetrahydrocannabinol (THC). Good evidence shows that secondary compounds in cannabis may enhance the beneficial effects of THC. Other cannabinoid and non-cannabinoid compounds in herbal cannabis or its extracts may reduce THC-induced anxiety, cholinergic deficits, and immunosuppression. Cannabis terpenoids and flavonoids may also increase cerebral blood flow, enhance cortical activity, kill respiratory pathogens, and provide anti-inflammatory activity.
Cannabis and Cannabis Extracts: Greater Than the Sum of Their Parts?

This is a good study for a couple of reasons, one, it outlines the effect of the most prominent cannabinoids, terpenoids, and flavonoids individually, as well as how they interact to give a unique medical benefit (high).

Secondly, this study contains a list of all prominent cannabinoids' boiling point, making it VERY useful for cooking or vaporizing.

    The tables with the specific vaporization temperatures are good, too, because you can set your vaporizer to specifically release certain cannabinoids. For example, if you want a more euphoric than sedating high, set your vape to 315˚F, to release more THC than CBN, which vapes at 365˚F.
    In a recent study, traces of THC were vaporized at temperatures as low as 140°C (284°F) and the majority of THC vaporized by 185°C (365°F); benzene and other carcinogenic vapors did not appear until 200°C (392°F), and cannabis combustion occurred around 230°C (446°F) (Gieringer 2001).
    Another good piece of information from the study.

    I think it would be worthwhile to do a fractional distillation on marijuana extracts. I know stateofhack was talking about doing one in F&B because someone was getting drug tested for probation. Because the metabolite that is tested for (THC-COOH) occurs after THC metabolism, one could smoke/vaporize only the other cannabinoids and theoretically still pass the drug test. I'm not sure if it ever went past the idea phase, though.

    As a corollary to this study, I have found a guide on how to separate CBD - which has anti-inflamitory effects - from other cannabinoids, namely THC.
    Accessing 0.5 to 2.0 Grams CBD Fractionating the Phytocannabinoids by Their Vaporization Points

    Here's more:

    Sorry for the multiple posts, it was going to page stretch either way... Also, sorry for any lack of coherency that occurred while I transferred the posts over from zoklet. Here is the original thread if anyone is interested:

    I have no idea what you're talking about but go ahead.

    THANK YOU THANK YOU THANK YoU Also lol at CBD being an anti-psychotic. Oh, the Irony of Reefer Madness!
