“At this time, surprisingly little is known about the impacts of cannabis on the development of cancer in humans,” said Dr. Callaghan, the study’s lead author. “With Canada and other countries currently experimenting with the decriminalization or legalization of recreational cannabis use, it is critically important to understand the potential harms of this type of substance use.”
The results from the recent study, as well as three prior case-control studies in this area, suggest that cannabis use may facilitate later onset of testicular cancer.
“Our study is the first longitudinal study showing that cannabis use, as measured in late adolescence, is significantly associated with the subsequent development of testicular cancer. My hope is that these findings will help medical professionals, public health officials and cannabis users to more accurately assess the possible risks and benefits of cannabis use.”
