What kind of carcinogens are in tobacco smoke?
Two important classes of tobacco smoke carcinogens are the polycyclic aromatic hydrocarbons (PAH) and the nicotine-derived nitrosamines. Recent studies have indicated that there is a strong coincidence of G to T transversion hotspots in lung cancers and sites of preferential formation of PAH adducts along the p53 gene.
While cannabis smoke has been implicated in respiratory dysfunction, including the conversion of respiratory cells to what appears to be a pre-cancerous state, it has not been causally linked with tobacco related cancers such as lung, colon or rectal cancers.
How are tobacco products harmful to your health?
All types of tobacco products contain chemicals that can be harmful to your health. Cigarettes, cigars, and pipe tobacco are made from dried tobacco leaves. Other substances are added for flavor and to make smoking more pleasant. The smoke from these products is a complex mixture of chemicals produced by burning tobacco and its additives.
How many chemicals are there in tobacco smoke?
