Im not even a stoner, I just wanted to see where he would stand on that issue.
My grandmother smoked from the age of 14 and lived to 85, died in her sleep, never had cancer once, and its very rare that anyone on that side of the family gets cancer, infact of her 13 kids, one of there kids had cancer and none of hers did. So Id argue thats more to do with genetics than tobacco, and think of all the shit they add to cigs, thats what causes the cancer if anything. Id say its more accurate to say that smoking promotes the growth of cancer rather than it causes it.
at any rate, I think all natural drugs should be legal, just treat abuse of them drugs the same as you would alchohol.
