The absolute worst advice you can give folks who have been banging their head against the wall, and finally found a way to stop, is "Oh no. Don't use that method. Go back and use the recommended products and methods. Maybe things will be different this time." Isn't that the definition of insanity--trying the same thing over and over and expecting a different result?
Mel, here are some facts. When used as directed, the FDA-approved nicotine products have a 7% success rate at 6 months, dropping to 5% at one year, and then to 2% at 20 months. Moore D, Aveyard P, Connock, M, Wang D, Fry-Smith A, Barton P: Effectiveness and safety of nicotine replacement therapy assisted reduction to stop smoking: systematic review and meta-analysis. BMJ 338:b1024 2009.
What other treatment would be considered effective with dismal success rates like these? In contrast, the range of smoking abstinence success rates for e-cigarettes is 31% to > 80%. The low range comes from studies that used a single brand of e-cigarette. The high rates come from surveys of forum participants who help each other with advice on pros and cons of various brands and styles of equipment, nicotine strength, and other alternatives. Here's a link to the results of one survey:

Our goal is not to be cured of nicotine "addiction." Our goal is to find a way to stop inhaling the tar, carbon monoxide, particulates, and thousands of potentially toxic and carcinogenic chemicals that are delivered by smoke. Those constituents, not nicotine, are what cause up to 99% of the smoking-related disease. When you take away the smoke, nicotine is about as harmful as another "addictive" drug, caffeine. See:

The smoking prevalence rates have stalled. Why force smokers to keep using products that don't work? Worse yet, why do you want to outlaw products that actually work?
