It's also worth pointing out that this particular study looked at the impact of long-term marijuana use on physical health, but not on mental health. "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." Despite some public health concerns about legal weed being "the next Big Tobacco," marijuana's toll on physical health appears to be far smaller. Still, Meier's latest study marshals up some convincing evidence that marijuana's toll on physical health may be far less than once feared. "The general lack of association between persistent cannabis use and poor physical health may be surprising," Meier and her colleagues write.
