What are the effects of smoking pure tobacco? Tobacco use is the one risk factor shared by four of the main categories of non-communicable disease. These include cardiovascular disease, cancer, chronic lung disease and diabetes. Smoking causes most lung cancers and can cause cancer almost anywhere on the body. Research conducted among smokers has shown that cigarette smoking (or nicotine administration) has several benefits, including modest improvements in vigilance and information processing, facilitation of some motor responses and perhaps enhancement of memory. Some people smoke as ‘self-medication’ to ease feelings of stress. However, research has shown that smoking actually increases anxiety and tension. Nicotine creates an immediate sense of relaxation, so people smoke in the belief it reduces stress and anxiety. Though its mechanism of action does help you feel better in the moment, smoking does not help with your depression overall. In fact, smoking is likely making your depression worse. By encouraging lower levels of dopamine, smoking impacts a chemical in your body that is associated with symptoms of depression.
