Each year over 5 trillion cigarettes are smoked by over one billion people.
Smoking is the single greatest cause of preventable deaths, and a leading cause of cancer and deaths associated with cancer.
Most smokers would like to quit smoking, but due to being addicted to nicotine, over 90% of those trying to quit relapse to smoking within one year.
Nicotine Replacement Therapy (NRT) products, such as chewing-gum and transdermal patches, are easy to use, accessible, affordable, and safe.
However, NRT products long term effectiveness is low, mainly because these products do not provide inhaled cigarette smoke taste satisfaction and do not accomplish similar to smoking nicotine doses, thus craving is only partially addressed.
