title: [Vitamin and tobacco smoking].
abstract: Nicotine addiction is one of the most prevalent addictive behaviors worldwide. According to World Health Organization (WHO), there are nearly 5 million tobacco- related deaths worldwide each year and nearly half of the smokers in the world today will die as a result of their addiction and the main cause will be the lung cancer. Some studies have suggested that intake of the carotenoids might reduce cancer risk. Unfortunately, supplementation with vitamins: beta-carotene alone or in combination with alpha-tocopherol or retinol increased risk of lung cancer incidence and mortality in cigarette smokers and individuals with occupational exposure to asbestos.
