Allysia Finley has a good piece in the Journal on “Cannabis and the Violent Crime Surge”:
Alex Berenson, author of “Tell Your Children: The Truth About Marijuana, Mental Illness and Violence,” pointed out that the New York Times had curiously removed from an article about the Uvalde school shooter a former co-worker’s recollection that he complained about his grandmother not letting him smoke weed. The Times didn’t append a correction to the story as it might be expected to do when fixing a factual inaccuracy.
Assuming the elided detail was accurate, it would fit a pattern. Mass shooters at Rep. Gibby Giffords’s constituent meeting in Tucson, Ariz. (2011), a movie theater in Aurora, Colo. (2012), the Pulse nightclub in Orlando, Fla. (2016), the 1`1234. First Baptist church in Sutherland Springs, Texas (2017), and Marjory Stoneman Douglas High School in Parkland, Fla. (2018), were reported to be marijuana users. It could be a coincidence, but increasing evidence suggests a connection.
