The chemistry of THC activation is the same whether you use a vaporizer or put it in a water bong.
So why does everyone talk about THC and not THC-COOH? Well, if you heat things with COOH groups, they can lose carbon dioxide and just be left with H (a hydrogen atom, not too polar). So when you heat THC-COOH in a joint by lighting the joint on fire, that heat causes the THC-COOH to lose CO2 and become THC (the same thing happens in a vaporizer).
In order for molecules to get inside your brain and have any effect they must pass through the blood-brain barrier. It is extremely difficult for polar molecules to pass this barrier. So, turning the more popular THC-COOH ( Which has extreme trouble getting into your brain and thus into your receptors) by use of HEAT and HEAT ONLY can the overwhelming majority of THC molecules get to your brain.
Now, the theory behind the use of vaporizers is very basic. People believe/assume that because they are not fully combusting the matter until it is a matter of carbon ash they are somehow consuming THC in a less harmful manner. Harm Reduction is the theory behind vaporizers. But is it true? Is it as effective as what is said or hyped.
Simple put, No. Its a falsification. Misinformation. The chemical process of turning THC-COOH into THC involved CO2. And in vaporizing, this CO2 does not magically escape or refuse to enter the human body. CO2 is a requirement to the activation of THC. Without it, we wouldn't get that high, as cannabis has very little natural THC in its natural state.
More so, of the known chemical compounds within cannabis ( this is a evolving variable-as one cannabis is not the same from specimen to specimen) all active at relatively low temps. Foreign chemical compounds, not native to the natural plant are a inmeasurable property because of its variation from specimen to specimen.
So, this talk of Vaporizing having less carcinogens and less harmful substances, from a scientific point of view, is merely speculation at best.
-sigh- you know a lot, but all of a sudden it seems you just forgot a bunch of stuff halfway.
You think that CO2 is the only unhealthy part about smoking? You think it's unhealthy at all? No....just no....
There's a LOT more stuff that's released while smoking that is NOT released while vaping.
All the "known" chemical compounds you speak of are ALL active. We want them ALL. So yes, they all have relatively low flashpoints - and they are all released in a vaporizer. But those are the good things.
The plant material - and tar and carcinogens released from smoking activate at much higher temperatures - some are even significantly changed in the process of combustion.
This doesn't happen with vaporizing - and I'm happy to show you several studies that prove this beyond a doubt. There is no speculation in this. I'm not sure what single article you read that led you to believe such hilariously misinterpreted information - but you're absolutely incorrect.
The high temperatures of combustion not only release FAR more chemical compounds (the percentage of actives in smoke is around 15%, the percentage of actives in vapor is 90%+), but they also destroy up to 50% of the THC you're trying to get. We aren't talking about foreign compounds not native to the plant - we're talking about the plant material itself.
Sorry, but your post couldn't possibly be more incorrect. You obviously read some decent articles to get your beginning information, but then failed to do more research to reach such a ridiculous conclusion.
Please attempt to prove me wrong though, I found your post amusing. I'm not sure what you think the other 85% of junk in smoke is. Vapor is quite pure.
