Toxins in Marijuana Smoke May Be Harmful to Health, Study Finds

Smoking weed may expose people to the same type of toxic chemicals found in tobacco smoke, a new study finds. People who only smoked marijuana had higher blood and urine levels of several smoke-related toxins such as naphthalene, acrylamide and acrylonitrile than nonsmokers. 

Marijuana smoke contains some of the same toxicants present in tobacco smoke. Marijuana smoking is prevalent among HIV+ individuals, but few studies have characterized smoke-related toxicants or associated health outcomes in exclusive marijuana users.
