Large Medical Cannabis Review Finds Scarce Evidence It Treats Mental Health Disorders

Summary: A massive new study looked at whether medical marijuana helps with mental health issues like anxiety and PTSD. The result? There isn't much proof yet. Researchers checked over 50 studies from 1980 to 2025 and found the evidence is pretty weak. This doesn't mean cannabis is useless, but past studies were often too small or too short. For example, it's hard to do a "blind" test because people usually know when they are high! Even though many patients use cannabis when standard medicines take too long or fail, scientists warn we need much larger, better tests to know if it's truly safe and effective.
