Cannabis is used by Americans across the country to treat all manner of health conditions, with the science backing up these health claims. But beyond the relief and euphoria that cannabis can offer, there's pushback to the legalization trend: experts say there's increasing evidence of long-term harms.

Marijuana Use Disorder
While one study estimated that approximately 3 in 10 people who use marijuana have marijuana use disorder, another study estimated that people who use cannabis have only a 10% likelihood of becoming “addicted.” The measurement and classification of cannabis use disorder as an addiction is controversial: as Dr. Grinspoon explains, “[cannabis] does help people. It helps people with anxiety, with pain, with sleep, with boredom, with loneliness…And it's not a simple thing to disentangle—you can't just write off a third of patients.”

Cannabis Use and Schizophrenia
Using Danish health records for over six million individuals, one study found that as many as 30% of cases of schizophrenia among men aged 21 to 30 could have been prevented had they avoided cannabis use disorder. The study author, however, flagged that Denmark does not have as much diversity as the US and that genetics do play a role in schizophrenia risk. Again, a correlation isn’t enough to imply causation, but the study findings may warrant caution.
