Marijuana arrests fall to lowest level since 1996

Arrests for simple marijuana possession in the United States fell to nearly a two-decade low last year, according to new statistics released Monday by the FBI.

The number of arrests for marijuana possession in 2015 -- 574,641 -- is the lowest number since 1996. It represents a 7 percent year-over-year drop, and roughly a 25 percent drop from the peak of close to 800,000 marijuana possession arrests in 2007.
