NPR (10/29, Chatterjee) reports a study found that “teens who start using cannabis before age 15 are more likely to use the drug often later in their lives.” Study results indicate that “they 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.” Researchers found that “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.” The findings were published in JAMA Network Open.
