What happens when it's day 31 and the cravings are still there? I quit smoking for 10 years, from the late 80's to the late 90's.
For reasons don't like to discuss I started again. In those years I cannot say I craved cigarettes every day but I sorely missed them many times.
The thing is that cigarette smoking is not just nicotine addiction. Proof of that is the fact that nicotine gums, patches and even nicotine inhalers have a lousy track record. Why? Part of it because (except for the patch) their product taste terrible. It is designed to almost gag you to "protect the children" (seems like we are going to start needing protection from the children one of these days).
A huge part of cigarette smoking is the ritual associated with it. I have not started with the nicotine free juices, but I have a feeling that when I do, I won't miss the nicotine that much. Like you, I am going to gradually phase it out. So I don't think it will be a big issue.
The ritual, the taste, is another matter.
How come quitting cigarettes almost always leads to weight gain? Nicotine is a pretty effective appetite suppressant, but a big part of it is also the oral satisfaction that goes with smoking. I venture to say that vaping fulfills that oral need quite well, if not better.
Like every smoker, my first order of juices was composed of a lot of cigarette like flavors. But the good folks on this forum are pretty clear that most folks don't like them but they do like the various flavors available. So I ordered some myself. Unfortunately, it's a hit and miss process, but some of the flavors I got I really enjoyed and I am going to buy more and try some others as well. The truth is that now I mix the "cig like" flavors with menthol, berries, and other flavors but I like the candy stuff better because they are truly delicious. Buch more flavorful than any cig I have ever had.
By the way, a few points about your last post:
Riva: I don't find it ugly at all. In fact, I have a black 501, shaped like a cigarette and I bought a silver Riva. I think the riva is actually quite good looking. Certainly better looking that the cigarette I rolled out of loose tobacco when I went through a period making my own cigs. But I am sure you are a much better roller than I ever was.
Smoking cessation: I am vastly ignorant about vaping, having only a couple of weeks experience. But I am pretty sure that e-cigs are not marketed as "smoking cessation devices" not because the manufacturers have not thought about it or they don't have the smarts to figure it out on their own. It's because when you market it as smoking cessation, you are basically selling medicine. As such, you have to fund studies, go through the various regulations and so forth. I read somewhere that marketing a new medicine can easily run about $100 million. A smoking cessation kit (beside that it would be illegal presently) is medicine.
Having been in manufacturing I can tell you that coming up with a new product is an expensive proposition all by itself. but complying with all the research, tests, applications, etc. for a new medicine is simply something that regular human beings can no longer do. It takes huge capital and infrastructure.
In fact, I know next to nothing about the companies that manufacture and distribute e-cigs. They may be big or they may be small. What I do know is that they are nowhere as big as RJ Reynolds or the other tobacco companies. How do I know that? Because I am pretty sure that they singly or as a group would love to be able to market e-cigs as a smoking cessation "cure". With all the smokers out there, they could afford to help them stop and still have a renewable supply of customers that would make the vaping community pale in comparison.
But there is no e-cigs company or even no conglomerate of them big enough to market e-cigs as a medicine and take on the FDA and BT. They are simply too small.
Heck, my guess is that for that to happen it would cost probably over $10 million in lobbying efforts alone.
Bottom line, while I do hope you find a way to quit smoking and I wish you best of luck with the quit smoking product, I am not holding my breath. Even in a different political and bureaucratic climate, even if you just wanted to come up with just a product to bring to market that needed no permit, no peer reviewed literature, no "oiling of wheels" in Washington or any red tape, you are still looking at several grand and at least 6 months to a year of 12 hour days. That's what any new product require of its inventor. Total commitment, ability to learn quick, innate skills and a certain amount of capital. Certainly more than a few bags of Tops.
But as a "drug", no way. It's just not going to happen.
