Are you a cannabis enthusiast? You might want to think twice before taking another puff. A recent study has uncovered a chilling connection between cannabis use and a heightened risk of developing head and neck cancer.
With about 51% of young adults reporting cannabis use within the past year,1 and usage on the rise, this research couldn’t be more timely.
The findings, based on an analysis of over 4 million individuals across 64 U.S. healthcare facilities, are concerning. As the cannabis industry continues to boom, reaching a staggering $20 billion in the U.S. alone, it’s crucial that we understand the potential risks associated with this increasingly popular substance.
The Study That’s Turning Heads
Led by Dr. Niels Kokot, a renowned head and neck surgeon from the USC Head and Neck Center, the study analyzed data from over 4 million individuals across 64 U.S. healthcare facilities.
The results were compelling: those with cannabis use disorder, a dependency on the drug, were found to be 3.5 to 5 times more likely to develop head and neck cancer compared to non-users.(ref)
The study, which is one of the largest to date investigating this link, compiled 20 years of data through a health research network that accounted for more than 90 million individuals. Researchers tracked cancer cases from one to five years of cannabis use to establish the association.
A Closer Look at the Numbers
The study delved into various types of head and neck cancers, including those affecting the mouth, pharynx, larynx, oropharynx, and salivary glands. The elevated risk held true across all demographics, regardless of age, gender, or ethnicity.
Even when accounting for other risk factors like alcohol and tobacco use, the link between cannabis and cancer remained strong.
Head and neck cancers account for approximately 4% of all cancer cases in the United States.(ref) The National Cancer Institute reports that around 69% of individuals diagnosed with oral or throat cancer survive for five years or more.(ref) However, if the cancer metastasizes, this survival rate plummets to 14%.
The Smoking Gun: Cannabis Smoke
So, what’s the culprit behind this alarming association? Researchers point the finger at the smoke produced when cannabis is ignited.
Packed with harmful chemicals, tar, and carcinogens, cannabis smoke can wreak havoc on DNA and trigger inflammation in the head and neck tissues. Over time, this damage can snowball into life-threatening cancers.
Experts raise concerns that the method of smoking marijuana—unfiltered and inhaled deeply, then held in the lungs for several seconds—could increase the associated risks.
Dr. Kokot emphasized, “Cannabis smoking is typically unfiltered and involves deeper inhalation compared to tobacco. Additionally, cannabis burns at a higher temperature than tobacco, increasing the risk of cancer-causing inflammation.”(ref)
A Wake-Up Call for Cannabis Users
As cannabis legalization sweeps the globe, these findings serve as a sobering reminder of the potential risks lurking in the smoke. Dr. Kokot emphasizes the need for more extensive research and increased public awareness about the link between cannabis and head and neck cancer. It’s time for individuals to make informed decisions about their health and well-being.
With the rising prevalence of marijuana use, there are concerns that the incidence of head and neck cancers may increase in the future. As marijuana continues to be widely legalized and accepted socially, we could see a corresponding increase in head and neck cancer cases if the association proves true.
This highlights the critical need to educate the public about potential risks and to conduct further research to understand the long-term effects of cannabis use on cancer development. While the allure of cannabis may be strong, the evidence linking it to head and neck cancer is impossible to ignore.
