Well it turns out that nicotine really isn't all that addictive -- no moreso than caffeine, for instance -- so yes, it's a little "habit-forming", but nothing like all the stupid ANTZ have led us to believe; most of the physically-addictive effects of smoking are due to supercharging the nicotine with ammonia, which causes it to be even more rapidly absorbed into the brain than it would anyway -- and it's already a lot faster with smoking, due to the microscopic particles being absorbed in the alveoli of the lungs, which means they go directly to the brain lickety-split -- and also the MAOIs, which are naturally-occurring in tobacco, which also account for a LOT of the addictiveness of smoking, and the pure psychosis and suicidal depression that can result from quitting. WTA contains some MAOIs, and the other natural tobacco alkaloids that occur in trace amounts compared to nicotine, but contribute a great deal to the physical addiction.
But the plain fact is that most of the addiction to smoking is behavioral, which is why vaping is such a marvelous substitute -- it closely mimics many of the behaviors we've come to depend on as stress-relievers. This is why it's so important to be smoke-free before you even try WTA; WTA won't provide the will to quit, or the commitment to quitting; that needs to already be in effect; WTA will just relieve most of the physical discomforts.
That's why a gradual transition to vaping from smoking is really the best and easiest way; it allows your brain and body to get used to the idea of something similar but slightly different; it allows you learn the best techniques for making vaping really effective -- such as, not inhaling deeply, but allowing the vapor to hang around in mouth and throat and nose, which provides far better absorption of vaporized nicotine; the alveoli are good at dealing with microscopic smoke particles, but vaporized nicotine is in droplets, which are much better handled by the oral, throat, and nasal mucosa. And it allows your "habit" to gradually come to understand that the sky isn't falling, nothing has changed all that much, you're just doing your accustomed thing in a slightly different way. All of that prevents stress, and since stress is one of the foremost triggers for smoking, it just makes the entire process much easier -- the less stress you suffer over it, the easier it will be, until you finally come to realize that you can't get anything from cigarettes that you can't get from vaping -- except a nasty smell on your hands and person, and a ghastly taste in your mouth -- and the more you vape, the worse that taste and smell will seem to you, which also makes the whole thing much easier.
When you get to the point where you're willing and eager to lay the cigarettes down, it's your own free choice, not coercion of any kind, and that is MUCH easier to stick to, than any kind of coercion.
