ATLANTA (CBS Atlanta) — It’s high time to put down that bong. A new study finds that people who use marijuana are more likely to develop testicular cancer.

The study published in CANCER, a peer review journal from the American Cancer Society, compared 163 patients who were diagnosed with testicular cancer to 292 healthy people and questioned participants about their drug use.

Researchers found that people who smoked weed on a daily basis were twice as likely to develop this type of cancer than those that didn’t.

“Compared with never use, ever use of marijuana had a 2-fold increased risk, whereas ever use of cocaine had a negative association with (testicular germ cell tumor),” the study stated.

Victoria Cortessis, assistant professor of preventative medicine at the Keck School of Medicine at USC and the study’s lead author, believes that the tumor cells could be responding to an active ingredient in marijuana.

“We do not know what marijuana triggers in the testis that may lead to carcinogenesis, although we speculate that it may be acting through the endocannabinoid system—the cellular network that responds to the active ingredient in marijuana—since this system has been shown to be important in the formation of sperm,” said Cortessis said in the study, according to Science Blog.

These new findings follow two other studies that linked the use of marijuana to testicular cancer.

According to the Centers for Disease Control and Prevention, the common age for men to develop testicular cancer is in their mid-30s.
