Quick Question About Burning Weed

I've read that thc is burnt as soon as the flame touches the weed, is this correct?




if so then wouldn't that mean that when you share a bowl with a friend the second person to hit it gets no thc ?

i know there is other things in weed that gets you stoned but im talking about just the thc.

I always believed it was the burning of the THC that got you high. I didn't think about the other persons in the rotation not getting stoned because you burnt up all the THC the first go-around. Maybe there is a technicality that ensures everyone gets stoned from the same bowl? Since the flame is pulled through the bowl-hole it does not actually burn ALL the THC the same way it would if someone were to torch the whole bowl. And also, you do not keep the flame to the bowl. You light it once, just enough to ignite the weed partially, then the next in-line gets to do the same thing and still achieve the desired results.

That is not true. If were so, weed edibles, green dragon, and THC pills (marinol) would not work. In fact, the THC must be unharmed (not burnt) to got you high.

To the OP, while the THC may be burnt when it touches directly the flame, most of it is only vaporized by the heat. Most of THC is into the bud, and thus does not touch the flame directly. When you toke, the stream of hot air from the flame and from the burning weed pass through the bud and evaporates some THC from it, which is inhaled and got you (and everybody else) high.

I think that if you roast the whole bowl and don't leave any green then a large percentage of the thc is gone, but as long as the bowl is still solid to the touch, it is still smoke-worthy

Ah yes! I forget about the edibles.

I've seen figures as high as 80% "smokable material" being instantly destroyed by lighter flame. The temperature at which the plant matter burns is higher than that of THC vaporization. Thus, burning plant matter implies THC has already been vaporized and dissipated.

A Bic lighter seems to generate temperatures of around double the point at which the plant starts to burn, thus destroying much THC on contact.

So if you consider that worst case scenario 80% of 10-15% THC content is destroyed, you're left with about 2-3% THC vapors per hit.

Edit - Unheated cannabis isn't absorbed by the human body, hence the use of lighters, ovens, and other heating devices to convert the inert resin, and the common use of 'activating' the cannabis by heating to sub-vaporization temperatures (converts more of the cannabinoids into those enjoyable by humans).

I dont agree with this. Thats to much of an extreme figure.

Try testing the idea! Get a bong or pipe...light it for yourself, and take the hit....pass it to a friend and have them hit...wait 10 min and ask them if they are blown!

You are prolly wasting SOME THC when you light the bowl for the first time but as long as there is greenery in the bowl you should be set!

it almost sounds as if you think the THC is only located on the outside of the bud.

Oh yes it is... :stoned:
The heating is used only to convert the THCA into THC, as usually the cannabinoids in the plant material are present in greater quantity as THCA(inactive) instead THC(active).
But if the weed is properly cured, all the THCA was already tranformed in THC, and if you eat this weed, or extract the resin with some solvent, thus making hash oil, and then ingest it, surely you will get high, even if the weed were not heated in the process.
