I do and will, not that I need your permission or anything. There are alot of things that are risky/bad for your health. Ever try driving? How about some of the food you may eat? Do you partake in alcohol? By some studies that will increase your risk for various sorts of cancer. Just living today puts you at risk of some forms of cancer.
Yep, those things are all true.
And smoking adds to every other risk of cancer you incurred today. That's all I'm pointing out.
Whatever things you do today that increase your risk of cancer, smoking on top of doing those things increases it even more.
I'm not anti-tobacco, or anti-weed. I have smoked before (not weed), and I support legalizing marijuana. But I don't support legalizing it because it's good for you or even not harmful-it is.
And so is smoking. That is the only point I'm making here. I think it is perfectly rational to decide that the increased risk of cancer, and the nearly certain general damage to your lungs, are worth the benefits you get from consumption of the product.
But again, let's not go overboard in countering the anti-smoking zealots-they are indeed right when they say that it significantly increases your risk of disease and that it generally damages your health.
