Could living near a cannabis shop actually improve your health? A groundbreaking new study suggests it might, at least in some surprising ways. But here's where it gets controversial: the same study also raises concerns about potential risks, especially for young adults.
A comprehensive study conducted in Oregon involving over 60,000 adults has revealed a fascinating connection between the proximity of cannabis retail stores and people's consumption habits. The research, spearheaded by David Kerr, a scientist at Oregon State University, indicates that easy access to cannabis shops is linked to increased cannabis use. Specifically, people who live closer to these stores are more likely to use cannabis frequently, defined as 10 or more days per month. And this is the part most people miss: the study also found a decrease in heavy alcohol consumption among those living near cannabis retailers. Could cannabis be acting as a substitute for alcohol for some people? It's a question worth pondering.
The research team's data spanned nine years and was drawn from the Behavioral Risk Factor Surveillance System, a continuous telephone survey managed by the Oregon Health Authority. Participants weren't required to know the locations of cannabis stores; instead, researchers cleverly linked participants' ZIP codes with the addresses of licensed retailers to determine proximity. This eliminated potential bias from participants consciously knowing where the stores were.
Professor Kerr emphasizes that residents living near cannabis retailers were more prone to using cannabis frequently, but also less likely to report heavy drinking habits. The Centers for Disease Control and Prevention (CDC) defines heavy drinking as consuming eight or more alcoholic beverages per week for women and 15 or more for men. So, the study suggests a potential trade-off: increased cannabis use coupled with decreased alcohol consumption.
Interestingly, this effect – more cannabis, less alcohol – was most pronounced in two specific age groups: individuals aged 21-24 and those 65 and older. This age-related difference is crucial. For younger adults, whose brains are still developing, increased cannabis use could pose unique risks. Kerr points out that the 21-24 age range coincides with the peak onset period for cannabis use disorder. This disorder involves continued cannabis use despite experiencing negative consequences, such as relationship problems, difficulties at work or school, or using cannabis in dangerous situations like driving.
"These and other findings suggest that age-informed, multilevel prevention efforts are needed," Kerr stated. "Communities would benefit from a range of policies that respond to the growing evidence that cannabis products and retail stores are marketed in ways that are appealing to young adults, many of whom live in areas with lots of retail access and who are more apt to buy high-potency products."
On the other end of the spectrum, older adults might be turning to cannabis for medicinal purposes, perhaps as an alternative to opioids for pain management. However, Kerr cautions that decreased perceptions of risk, combined with potentially unfounded medicinal uses, could introduce new health risks for this age group. It’s a delicate balance between perceived benefits and potential harms.
"It's a complicated picture," Kerr acknowledges. "Cannabis is considered effective for certain conditions like chronic pain, it poses less risk than opioids, and less drinking is better for your health than more drinking." This highlights the complexity of the issue – it's not simply a matter of good versus bad, but rather a nuanced understanding of potential benefits and risks across different demographics.
Kerr believes that people aren't necessarily choosing where to live based on the proximity of cannabis retailers. Instead, he suggests that increased access may be influencing people's behavior. This subtle distinction is important because it implies that policy interventions might be more effective if they focus on regulating access rather than trying to change people's residential choices.
Oregon legalized recreational cannabis retail sales in 2015. While state law allows counties and cities to ban retail cannabis operations, county bans only apply to unincorporated areas. This patchwork of regulations creates a complex landscape for cannabis access across the state.
"Retail access to cannabis products can be regulated through an array of approaches and enacted at different levels of government," Kerr concluded. "Careful consideration should be given to policies and prevention efforts that balance the goals of cannabis legalization against potential harms." The research was supported by the National Institute on Drug Abuse of the National Institutes of Health. The findings are available in preprint form and are slated for publication in the American Journal of Preventive Medicine.
This study raises some crucial questions. Should we be more concerned about the marketing of cannabis to young adults? Is cannabis a viable and safer alternative to alcohol for some people? What role should local governments play in regulating cannabis access?
