PainRelief.com: What is the background for this study?

Response: Though rates of tobacco use are declining, rates of cannabis use are increasing as it becomes more widely legal and available. Though there is not as much research on the long-term health effects of cannabis, cannabis and tobacco smoke contain many of the same carcinogens and toxins and both have particulate matter than is harmful when inhaled.
