 Summary:Secondhand marijuana smoke may have similar cardiovascular effects as tobacco smoke. Lab rats exposed to secondhand marijuana smoke had a 70 percent drop in blood vessel function.

“If you’re hanging out in a room where people are smoking a lot of marijuana, you may be harming your blood vessels,” he said. “There’s no reason to think marijuana smoke is better than tobacco smoke. Avoid them both.”

Secondhand tobacco smoke causes about 34,000 premature deaths from heart disease each year in the United States among nonsmokers according to the U.S. Surgeon General’s 2014 report on the consequences of smoking.

More research is needed to determine if secondhand marijuana smoke has other similar effects to secondhand cigarette smoke in humans.
