Skin cancer... Dont think anyone ever claimed it can cure cancer, but it can lessen the pain so what's the harm in that?

I agree it doesn't cure cancer, but it helps with the pain from chemo.

Haha, yeah I'm not gonna go that far. I don't think smoking weed is any worse than drinking. They both have the potential for abuse and probably some impairment on driving. Given my personal experience though, I'd say any impairment to driving from smoking some pot is dwarved by the effects alcohol has. I used to smoke so much weed that I was at least a little high 9/10 times I was behind the wheel. I'd smoke before my morning commute to work every day. This went on for years, and I've never had an accident or hit anything in a motor vehicle. I'm pretty sure if I'd been drinking instead that I would've faced some pretty significant consequences from either the law or my own impairment. I've been in the car with a drunk driver before (didn't know he had been taking shots before we got in) and it was one of the most frightening experiences of my life. Luckily we founded out he was drunk when he drove down the street to a gas station and hit a parking barrier 3 times in a row and not from a collision.
