Smoking marijuana exposes the body to some of the same toxic chemicals released from tobacco, but at lower levels, according to a new study.
Scientists at Dana-Farber Cancer Institute and the Centers for Disease Control and Prevention looked at the levels of several dangerous chemicals in the blood and urine of 245 volunteers.
Some of the volunteers didn t smoke, some smoked either weed or tobacco and dome smoked a combination of both.
They found that those who only smoked marijuana still had several smoke-related toxic chemicals in their system - but at lower levels than those who also or only smoked tobacco.

(CNN) Smoking weed may expose you 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, according to the study published Monday in the journal EClinicalMedicine.
Naphthalene is associated with anemia, liver and neurological damage, while acrylamide and acrylonitrile have been associated with cancer and other health issues. Marijuana use is on the rise in the United States with a growing number of states legalizing it for medical and nonmedical purposes - including five additional states in the 2020 election, said senior author Dr. Dana Gabuzda, a principal investigator in cancer immunology and virology at the Dana-Farber Cancer Institute in Boston, in a statement.
