The spin in the title (which differs greatly from the original article) is very misleading, and seems to cherry pick from the article's conclusions, which are very clearly stated:<p><i>Key Points</i><p><i>Question: Does cannabis use increase the risk of psychiatric disorders?</i><p><i>Findings: In this survey of a nationally representative sample of US adults, cannabis use was associated with significantly increased risk for developing alcohol, cannabis, and other drug use disorders as defined by the DSM-IV at 3 years of follow-up. However, cannabis use was not associated with increased risk for developing mood or anxiety disorders.</i><p><i>Meaning: Cannabis use is associated with an increased risk of developing drug and alcohol use disorders.</i><p>So they very clearly stated "Cannabis use increases risk X, but not risk Y." But for some reason you've chosen a title which says "Cannabis doesn't increase risk Y", as if that was the main message of the article. It wasn't.
