Cannabis smoking may trigger the development and spread of cancerous cells and tumors in the lungs and testes.
This meta-analysis reviewed data from previously published studies that examined the correlation between cannabis smoking and the risk of cancer. Researchers compiled data from 18 studies involving over 13,000 patients diagnosed with cancer and more than 150,000 healthy persons.
Researchers discovered that participants' susceptibility to lung and testicular cancers increased with regular smoking of cannabis. Usage of cannabis for more than 10 years was associated with a significant rise in the risk of testicular cancer in this study. This meta-analysis highlights the detrimental effects of cannabis on both lung and testicular health.
