I am looking for the answer of if the particles of smoking in cannabis could cause anxiety, and if convection or vaping cannabis takes the anxiety part of it away. (At least, cannabis induced anxiety).

What are the variables of smoking cannabis? What does smoking cannabis do? What do these molecules do outside of the role of cannabis?

In order to know the answers to these things, I need to research the studies on smoking cannabis and their effects.

There are a lot of short studies that aren't that helpful, but this study in particular

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6610518/

• What they did was take multiple types of strains with different THC percentages and put them through a smoking machine. They were looking to test for the amount of toxins and carcinogens in smoking cannabis next to nicotine. They found conflicting results, however. It seems as though the higher the THC percentage, the higher particles you smoke throughout; but there were some that had more toxins than others in the smoke. In fact, they found a lot more terpenes than they did toxins. ^262f2e
• They also said this in their conclusion:

Estimations that up to 50% of the Δ9THC is lost in sidestream smoke, up to 30% is destroyed by pyrolysis and 10% is trapped in the butt of the joint have been reported

^20f998

The potential for terpenoids to be precursors for carcinogens highlights the question of smoking technique, as smoking cannabis joints with higher levels of Δ9THC may lead to higher levels of carcinogens such as B[a]P.

The results also showed that the percentage of TPM accounted for by Δ9THC has a tendency to reach a maximum at higher potencies. This suggests that once the cannabis reaches a certain Δ9THC level, the smoker receives a consistently higher ratio of Δ9THC to TPM, whereas at lower potencies the smoker receives less Δ9THC per unit of TPM, and this raises the question of whether or not there are health benefits in smoking cannabis with a higher _C_THC.

• TPM=total particulate matter (TPM)
• cTHC=concentration of delta 9 THC

==So, what this concludes is although it's not the same across the board, the higher the THC percentage, the higher chance you get toxins such as carcinogins, benzoapryne, and hydrocarbons. etc. And even terpenes can play a part of that, but they can also counter-act that because of their medical properties.

Okay, so now we can try to define these compounds and what they do.

Benzoapryne:

Benzo[a]pyrene

(

B_a_P

or

B[a]P

) is a

polycyclic aromatic hydrocarbon

and the result of incomplete combustion of

organic matter

at temperatures between 300 °C (572 °F) and 600 °C (1,112 °F). The ubiquitous compound can be found in coal tar, tobacco smoke and many foods, especially grilled meats. The substance with the formula C20H12 is one of the

benzopyrenes
