UNLESS THEY QUIT –
Oct. 29, 2025 – Teens are also more likely to develop mental and physical health problems in young adulthood compared to their peers who did not use the drug in adolescence. Early, frequent cannabis users had a 51% higher chance of seeking care for mental health problems in young adulthood compared to those who didn’t use the drug. And that risk was calculated after controlling for a range of confounding factors that are known to influence health, like bullying or lack of parental involvement.
Similarly, early and frequent users of cannabis had an 86% higher chance of needing care for physical health needs. “We have some indication that respiratory problems were most frequently reported and also accidents and unintentional injuries,” says Orri.
These physical health problems may have to do with intoxication from cannabis, but could also be due to withdrawal symptoms, write Orri and his colleagues in the paper.
