No, vaping should replace tobacco. Weed doesn't help you get over a nicotine addiction. But with vaping, you can actually alter the amount of nicotine you are receiving, while still getting the oral fixation of smoking. Much easier to get off of a nicotine addiction that way. Weed shouldn't/won't replace anything. Even with it being illegal, the people who would be smoking if it were legal (save for the edgy teenagers) are smoking it anyways. Now they just have to hide it less. Nicotine and THC do very very different things to you, I wouldn't want my surgeon to be stoned off his ass while doing heart surgery, but if he smoked a cigarette before to relieve stress, it would hardly affect his ability as much (as compared to weed) to conduct fine motor skills, concentrate, and utilize knowledge. Being high while driving [i]does impair your driving skills,[/i] smoking a cigarette impairs it to the point that you have to drive with one hand, which is easy, and isn't actually having physiological affect on your decision making skills. To say that weed should replace tobacco is just an idea that you'd either have to be really stoned or ignorant to think as valid.
