Nicotine has a few positive effects on the body. It stimulates memory and alertness, enhancing cognitive skills that require speed, reaction time, vigilance, and work performance. It acts as a mood-altering agent, it tends to alleviate boredom and reduce stress, and reduces aggressive responses to stressful events. It also tends to be an appetite suppressant, specifically decreasing the appetite for simple carbohydrates (sweets)

Smoking can also lead to premature fine wrinkles. These may be caused by crinkling up eyes against smoke, or from the constriction effect of nicotine on small blood vessels in the skin.[4]

There are treatments for people suffering from lung cancer, but there is no known cure. The kinds of treatments used are surgery (removing the cancer), radiation therapy (using high-dose X-rays or other high-energy rays to kill cancer cells) and chemotherapy (using drugs to fight the cancer). Chemotherapy is the most popular method of treatment but many people are dubious when it comes to making a choice about it because of its many side effects. Oncologists cannot treat only cancer cells with this technique so many other cells are also eliminated. For example cells of hair follicles, stem cells of blood cells in the bone marrow and cells of oral mucosa. The common side effects of chemotherapy include gastrointestinal symptoms (vomiting, nausea, etc), anaemia, infection (white blood cell production may decrease), mucositis, fatigue, alopecia (hair loss) and depression. Researchers are trying to combat these side effects and there are several new methods of treatment, which are being tested. These include Photodynamic Therapy, Immunotherapy, Gene therapy, Cytokines, Interferons, Onconase and L-NDDP. Once these treatments are tested to be effective and safe, a person suffering from lung cancer can be less dubious about being treated and hence the deaths caused by lung cancer would decrease. [6]

A smoker may still want to argue that fewer smokers get Alzheimer's and Parkinson's diseases than non-smokers. Researchers knew this for a while and up to April l992, of the 17 studies on Alzheimer's and smoking which had been published in peer-reviewed journals, 13 reported a reduced risk for smokers and only four found no difference between smokers and non-smokers.
