Nicotine is an addictive substance that can cause dependency in regular users. Nicotine is found in tobacco, which is used in cigarettes, pipes and cigars. If you are dependent on nicotine and can't stop smoking, nicotine can actually help you quit. A gum, lozenge, patch or other supplement that contains nicotine can diminish cigarette cravings by allowing you to taper off nicotine slowly, preventing symptoms of nicotine withdrawal and helping you stop smoking for good.
Function
Nicotine is a drug that causes a short spurt of good feelings in both the mind and the body after it is ingested. Nicotine can be absorbed into the body through the skin, the mucous membranes or the lungs. When nicotine is taken in a controlled and tapering amount, it can reduce cravings for cigarettes or other tobacco products. Some nicotine patches, gum and other devices are sold over-the-counter, while others are available by prescription only.
Types
Nicotine can be administered in the form of a nicotine gum, lozenge, patch, inhaler or nasal spray. Brand names of products designed to reduce symptoms of nicotine withdrawal and help individuals stop smoking include Habitrol, Nicorette, Commit, Nicoderm, Nicorelief and Nicotrol. A doctor can recommend a particular smoking cessation aid depending on the smoking habits of the individual and the ease of use for the patient.
Considerations
Individuals who are pregnant, may be pregnant or are thinking of becoming pregnant should not use products containing nicotine. Additionally, women who are breastfeeding should not use smoking cessation products. Depending on the patient's medical history, a doctor may choose not to prescribe a particular nicotine cessation medication. For instance, if the patient has sinus problems, a doctor may choose not to prescribe a nicotine nasal spray, and if the patient gets frequent skin rashes, a doctor may choose not to prescribe a nicotine patch.
Effects
In some cases, nicotine withdrawal can cause adverse symptoms, even when tapering slowly from nicotine with the help of a smoking cessation medication. Side effects of nicotine withdrawal include nausea, headache, dizziness, cold sweats, diarrhea, headache, fatigue, difficulty concentrating, dry mouth, irritability and other behavioral changes. Nicotine withdrawal symptoms are usually mild or moderate, but in some cases may be severe and require the immediate care of a doctor.
Expert Insight
Contrary to popular belief, nicotine does not cause cancer, states the Mayo Clinic. Although nicotine is the addictive additive in cigarettes, smoking cessation treatments provide nicotine without the multitude of chemicals that are absorbed into the body by inhaling cigarette smoke. Therefore, nicotine replacement therapy is a recommended treatment for individuals who are trying to quit smoking to "help relieve difficult withdrawal symptoms and cravings," according to the Mayo Clinic. For individuals who have been having difficulty quitting smoking, nicotine replacement therapy may provide more successful results.
