Pot legalization has not had the negative effects that drug warriors predicted

See Remorse by Scott Sumner. Excerpt:

"Tyler Cowen linked to a Wonkblog post that suggested pot legalization has not had the negative effects that drug warriors predicted:

National surveys have shown that teen marijuana use rates are falling across the country. But there haven't been many numbers available specifically for states such as Colorado and Washington where it is legal. Federal data released late last year showed that teen use rates in Colorado and Washington were essentially flat, but they covered only 2014, the first year commercial marijuana was available in those states. 

The latest data from Colorado includes 2015, reflecting two full years of the legal marijuana market's effect. These numbers give the strongest indication yet that fears of skyrocketing adolescent use have not materialized.

Here are some of the groups opposed to pot legalization:

Among the groups opposing marijuana legalization in the state are the California Hospital Association and the California Correctional Supervisor's Association. The state's report on the measure's fiscal impact on state and local government shows it could save "tens of millions of dollars to potentially exceeding $100 million annually" due to savings in the courts, police and corrections.

Of course, saving money on corrections means a loss of income to corrections officers."
