oh slim, this is like a whole new carbon discussion for you.
a recent longitudinal study (cant remember if it was a university in socal) showed no statistically significant increase for cancer rates or respiratory damage from even high frequency cannabis smokers.
of course, if you want to be super healthy, you could always eat it, drink it, rub it in, or vaporize it.
there are plenty of good documentaries and peer-reviewed scholarly articles detailing a wide range of its benefits, and lack of significant
health risks. of course, if you are using old gubbamint research which did not use controls for individuals with family or personal histories
of psychological disorders, then its understandable why you might make such a ludicrous claim.
the next thing you know, you will make claims that lsd and certain mushrooms have no medical benefits, and that they will make you go crazy.
oddly enough, prior to its 1930s prohibition, cannabis was often used to treat asthma.
and natural tobacco isnt too bad for you, and alcohol is not either (for the record, i have touched tobacco, and am not fond of alcohol).
