In discussions about substance misuse, the focus today is often on drugs such as opioids, the drugs that are responsible in large part for the addiction and overdose crisis. However, other drugs that seem less dangerous to the public at large nonetheless need to be given consideration as well. Drugs such as marijuana can have serious long-term health impacts, including cancer, according to the Colorado Department of Public Health.
What Causes Cancer?
In Colorado, more than 20,000 people are diagnosed with cancer each year. One third of those diagnosed eventually die from the disease. There are a number of different behaviors that increase the likelihood of getting cancer in your lifetime. These include an exposure to chemicals or radiation, a poor diet, obesity, alcohol use, and smoking. Cancer risk also comes from factors that people cannot control, such as their family history and their age.
Marijuana Use and Cancer
Marijuana contains many of the same chemicals as tobacco, so it is prudent for those interested in public health to examine the possibility that it could also be a factor in cancer diagnoses and deaths.
Studies that look at the potential links between marijuana use and cancer calculate the number of “joint years” that people use marijuana. A joint year is an average smoking frequency of one joint a day per year. According to the Colorado Department of Public Health, those who have smoked fewer than 10 joint years usually do not have an increased risk of most cancers, while those who have smoked more than that may have an increased risk of cancer. This does not mean that you need to have smoked for 10 years; you could accumulate joint years more quickly because you smoke more than one joint per day.
The studies do not link marijuana use in a strict cause and effect format. Instead, they recognize that there are a number of factors that influence cancer risk, and this could be one of them. For instance, it is difficult to draw out data specific to marijuana use if people also eat poorly, drink alcohol, or smoke tobacco.
A Key Finding: A Link Between Marijuana Use and Prostate or Testicular Cancer?
During the Colorado study’s literature review, they discovered data that suggests a link between nonseminoma testicular cancer, prostate cancer, and marijuana use. Marijuana use was definitely associated with nonseminoma testicular cancer and there was some evidence for a link between marijuana use and prostate cancer.
The Long-Term Effects of Cannabis
While cannabis might seem like a lighter drug to some, the long-term effects of cannabis can potentially be serious. According to Dana Farber, even though marijuana is still illegal at a federal level, “the expansion of state laws decriminalizing or sanctioning its use is likely to renew the debate over whether smoking marijuana increases the risk of developing cancer.” As marijuana use becomes a more legal part of society, it is still important to remember that, like alcohol and tobacco, a substance is not healthy simply because it is legal. Men who are considering using marijuana should be forewarned that there could be a link between testicular and prostate cancer and marijuana use.
