The findings raise concerns about the health consequences of cannabis use among people with diabetes. Previous studies have found cannabis use to be associated with adverse cardiovascular outcomes, to which people with diabetes are already vulnerable.

The researchers note that the use of cannabis among adults with diabetes may be driven by its perceived therapeutic benefits, including insomnia and pain relief for neuropathy. Additionally, the legalization of cannabis in multiple states has resulted in increased access to cannabis products, leading many people with chronic illnesses to turn to cannabis as an alternative means to manage their symptoms.

The study also found that individuals with diabetes who engaged in other substance use, such as tobacco use, binge drinking and misuse of opioids and stimulants, were more likely to have used cannabis. Use of these additional substances could further exacerbate the health risks associated with diabetes and also emphasize the importance of addressing polysubstance use among adults with diabetes.

The study’s findings highlight the need for health care providers to screen for cannabis use among their patients with diabetes and to educate them about the potential risks and benefits of its use. Further research is also needed to understand the effects of cannabis on diabetes outcomes and to develop evidence-based guidelines for its use in this population.
