The legalization of cannabis has made it hard to walk down the street in some urban centers without inhaling a good dose of smoke from weed. And chewables are everywhere.

As of April 2025, 39 states, three territories, and the District of Columbia allow cannabis use for medical conditions, and 24 states, two territories, and the District of Columbia have legalized nonmedical adult cannabis use.

But just like alcohol, legalization doesn't mean marijuana is entirely safe. 

A report delivered at the meeting of the European Association for the Study of Diabetes looked at five years of data on millions of people and found that new cases of diabetes were four times higher in those who used cannabis, compared to those who didn't.

Whether it's because people get high and munch on unhealthy foods and adopt sedentary behavior, because the active ingredients in weed alter metabolism, or because there are other not yet identified effects, the researchers couldn't say.

But if you’re going to indulge in cannabis, you need to pay attention to your use and have your doctor keep tabs on your glucose levels.

In addition, pay attention to how your mood is affected by the super-potent strains of cannabis out there these days. There's evidence (not conclusive) that a strong dose may promote depression and anxiety, and it seems that real dependence on the stuff amps up the risk for psychosis and schizophrenia in susceptible people.

For alternative ways to relax and have fun, try yoga, tai chi, meditation, and enjoying walks and talks with your posse.
