Drug use can lead to a variety of respiratory problems. Smoking cigarettes, for example, has been shown to cause bronchitis, emphysema, and lung cancer. While chemical analyses that compare the profiles of electronic and traditional cigarettes have suggested that e-cigarettes have a reduced carcinogenic profile; toxicants, carcinogens, and metal particles have been detected in the liquids and aerosols of e-cigarettes, and it is currently unclear what risk they pose to the lungs with repeated use. In addition, there have been serious lung illnesses and deaths related to vaping both marijuana and nicotine. Many of these illnesses have been linked to the additive Vitamin E acetate, and the government provides regular updates for the public.
