Everything has it's plusses and minuses. I would hope that those of us who love smoking, understand it is a drug (btw there is a distinction b/t drug and psychoactive drug, of which weed is both), and that inhaling smoke of any kind is hazardous. Isn't it less so if you smoke monthly compared to blasting bong hits daily? Of course. And of course there are more dangerous drugs out there, but lets be real. It's probably not going to kill you, but it's also not 100% safe.

BTW- if weed HASN'T increased potency significantly over the years, that is a PATHETIC statement about growers. The principles of natural selection would apply- the dna of the "strongest" plants should be selected more than the weaker ones. The only confounding variable here (and relates to the above issue), is that THC is not the only drug in weed. We haven't even studied all of the psychoactive chemicals in weed, much less the thousand or so other chemicals created when combusted. So it could be that when we are selecting the most powerful plant, there is a chance we are also selecting the effects of an altogether different chemical in addition to THC!
