I never said it DOESN'T have side effects, any combusted material you inhale is gonna be unhealthy for your lungs, reduce their capacity, a risk for cancer, etc. But that's not an inherent risk of Marijuana itself... it's not the plant's properties that are damaging to the lungs, you would get the same effects from smoking earl grey tea or grass (real, actual grass) or whatever.
And, again, it's impossible to overdose on THC. The same can not be said of alcohol, tobacco or even caffeine.
People, I'm not there trying to "promote" pot, I'm not saying it's GOOD for you... it's a drug, you have to realize this before taking the rational decision to partake. What I'm saying is that, given our society's "accepted" and legal drugs, pot is very minor in comparison in ill effects.
After I did my research on the effects of pot the biggest decision I had was to reduce to almost nil my alcohol consumption. Booze is whack, yo. Pot.. not as much.
