There was a time when the government, the healthcare industry, and even Hollywood went to great lengths to warn young people about the dangers of smoking marijuana. Now, pot is legal for adult recreational use in 10 states, and New Jersey is poised to become the 11th. Democratic Gov.

Mike Davis, who covers pot for the Asbury Park Press and USA Today Network, joins us on this episode of The Why.
