What Pot Really Does to the Teen Brain
How much should we worry?
By Claudia Wallis | Scientific American December 2017 Issue
American parents have been warning teenagers about the dangers of marijuana for about 100 years. Teenagers have been ignoring them for just as long. As I write this, a couple of kids are smoking weed in the woods just yards from my office window and about a block and a half from the local high school. They started in around 9 A.M., just in time for class.
Exaggerating the perils of cannabis—the risks of brain damage, addiction, psychosis—has not helped. Any whiff of Reefer Madness hyperbole is perfectly calibrated to trigger an adolescent's instinctive skepticism for whatever an adult suggests. And the unvarnished facts are scary enough.
