Patches deliver nicotine through the skin in different strengths, over different lengths of time.
Depending on the brand you use, may be left on for anywhere from 16 to 24 hours. Some smokers who use these products can stop them abruptly, while others prefer to reduce their dosage slowly. Although it actually is a gum-like substance impregnated with small amounts of nicotine, nicotine gum is not chewed like regular gum. The nicotine is absorbed through the lining of the mouth.
