Yeah it's definitely not the same with different drugs. The urges triggered by smell of cigarette smoke, I personally feel is more a mental thing, ie. the power of suggestion. It's separate from the physical dependence. Vaping may remove the smell triggers, but having smoked for a long time, and having vaped a fair amount as well, I suspect that while vaping may be much healthier, it could end up being more addictive due to the way it tends to be used along with differences in the way it's inhaled. When light cigarettes were first introduced, they also thought they would be healthier, but many people actually tended to pull harder on a light cigarette than the regular cigarettes, resulting in smoke being pulled more deeply into the lungs actually doing more damage.
