More evidence for why banning smoking is a good thing

[Weltall]

With smoking, it is indeed direct, but the difference is, it's not acute. Smoke-related cancers almost always require years of heavy exposure to develop. If I sit and have dinner at Smooky's Corn Blaster Shack one night, and there's smoke in the air, the worst that's going to happen is that my clothes will stink of it. The effect on my overall physical health will be no worse than what the corn blasters did to my upper GI.

Alcohol is another matter entirely. It can make anyone into a killer overnight.
