That has been studied, of course. It's hard to believe most information about cannabis due to the decades of government-corporate propaganda against it.

Tobacco is highly toxic. Cannabis is not at all toxic, and in fact beneficial. That makes a difference in the smoke.

I read a report from the UK saying that cannabis's antioxidants and other helpful chemicals made up for any harm it caused by smoke.

One can vape anyway, and most serious enthusiasts dab.
