A study by Australian researchers found that children of mothers who had cannabis use disorder while pregnant are 79% more likely to have any anxiety disorder and 146% more likely to specifically have PTSD. It is painfully ironic that something marketed to moms to “mellow out” goes on to give their kids anxiety disorders. But these ugly ironies seem to be the norm with marijuana: The “peaceful hippie” drug has deep links to violent and antisocial behavior; the “harmless plant” causes heart attacks; the “mindfulness” booster brings on severe mental illness. It’s beyond clear: the “cannamoms” need to cut it out ASAP.
