DD, thanks for mentioning CBD, as THC is the ingredient that seems to be mentioned the most in articles about marijuana .. actually if one was inclined to place them in a good guy/bad guy scenario .. reading this one .. http://en.wikipedia.org/wiki/Cannabidiol .. it looks cannabidiol would be the good guy ..
One thing for sure bonging catches a lot of the tar before it reaches the lungs .. to balance that to some degree, i guess, there is more smoke wasted in smoking a joint or a cigarette.
It was Plato who said, “He, O men, is the wisest, who like Socrates, knows that his wisdom is in truth worth nothing”
