Smoking addiction has been said to parallel that of cocaine and heroin. The psychological dependency is even harder to overcome due to the availability of tobacco and its lethal, addictive drug - nicotine. Over the past two decades, stop smoking programs have come and gone, with little impact on the addiction. Most of these programs or medications, including: nicorette gum, the "patch", Zyban and others show a success rate of only 30-35%. Quitting “Cold Turkey” is even worse with a success rate of about 5%.
