A new study that spanned 11 years found that smoking marijuana may lower the chances of getting bladder cancer.

The study’s not been peer-reviewed yet, USA Today reported. It involved 83,000 men who smoked marijuana, cigarettes or both, Raw Story reported.

The findings, presented at the American Urological Association, found that men who smoked cigarettes increased their risks of bladder cancer, but that men who smoked marijuana only actually decreased their risks, Raw Story reported. Further, the study found that men who smoked both still have a higher chance of bladder cancer, but it was still a lower chance than those who smoked only cigarettes, Raw Story said.
