Quitting smoking or smoking cessation is the effort to stop smoking tobacco products. With nicotine an addictive substance, many people find it hard to stop smoking without help. Various approaches are available, both psychological and pharmacological, although success rates are relatively low. Psychological support, group therapy or cognitive behavioral therapy allows many people to quit. Medication helps these approaches, although medication without psychological support is generally discouraged and some of the medical therapies themselves have proven addictive and, potentially, dangerous.
