Secondhand marijuana smoke is more harmful for blood vessels more than secondhand tobacco smoke, according to a new study.
Research released by the American Heart Association showed that exposure to weed smoke for one minute made rats’ vessels less efficient for 90 minutes.
A minute of tobacco smoke had similar effects, but only for 30 minutes.
University of California San Francisco’s Dr. Matthew Springer said in a release that human and rats blood vessels are similar, and that the results counteract the belief that exposure to marijuana smoke is harmless.

People who wonder if the glass is half empty or full miss the point. The glass is refillable.
A brownie a day will keep the effects of second hand smoke away.
