Long-term marijuana use is not associated with a raft of physical health problems, according to a new study, with one surprising exception: gum disease.
Researchers led by Madeline Meier of Arizona State University tracked the marijuana habits of 1,037 New Zealanders from birth to middle age to see what effect those habits have on some common measures of physical health, including lung function, systemic inflammation, cholesterol levels, blood pressure, body weight, blood sugar, and dental health.
What they found was surprising: After controlling for other factors known to affect health, especially tobacco use and socioeconomic status, marijuana use had no negative effect on any measure of health, except for dental health. People who smoked more marijuana had a higher incidence of gum disease.
The cause is something of a mystery. Meier and her colleagues did find that heavy marijuana users were less likely to brush and floss than their not-marijuana-using peers. But even after controlling for dental hygiene, the relationship between marijuana use and poor dental health persisted.
“In general, our findings showed that cannabis use over 20 years was unrelated to health problems in early midlife,” the study, published in the journal JAMA Psychiatry, found. “Across several domains of health (periodontal health, lung function, systemic inflammation, and metabolic health), clear evidence of an adverse association with cannabis use was apparent for only one domain, namely, periodontal health.”
In some domains, marijuana use was associated with better health outcomes: “Findings showed that cannabis use was associated with slightly better metabolic health (smaller waist circumference, lower body mass index, better lipid profiles, and improved glucose control),” the study determined. However, these associations were fairly small and by no means strong enough to recommend regular cannabis use as a weight management strategy.
The findings were more striking when measured against the effects of tobacco use over a similar period.
“By comparison, tobacco use was associated with worse periodontal health, lung function, systemic inflammation, high-density lipoprotein cholesterol levels, triglyceride levels, and glucose levels in early midlife, as well as health decline from ages 26 to 38 years,” the study found. Despite some public health concerns about legal marijuana being “the next Big Tobacco,” marijuana’s toll on physical health appears to be far smaller.
