The link between pot and mass shootings may be closer than we think

It makes no sense at a time when American youth is suffering from an unprecedented mental health crisis.
And, in all honesty, we cannot rule out a connection between increasing marijuana use, mental illness and the recent spate of mass shootings by disturbed young males.
You can’t address the youth mental health crisis without considering the effect of rising teen marijuana use.
Among American teenagers, the drug’s “daily use has become as, or more, popular than daily cigarette smoking” according to the National Institute of Health’s 2017 Monitoring the Future study.
