Smoking hazards

The addictive effects of tobacco have been well documented. It is considered to be mood and behavior altering, psychoactive, and abusable. As a multisystem pharmacological agent that is voluntarily administered, tobacco is believed to have an addictive potential comparable to alcohol, cocaine, and morphine. Tobacco and its various components increase the risk of cancer (especially in the lung, mouth, larynx, esophagus, bladder, kidney, pancreas, and cervix), heart attacks and strokes, and chronic lung disease.
