The report finds that between 2001 and 2010, there were over 8 million marijuana arrests in the United States, 88% of which were for possession. Marijuana arrests have increased between 2001 and 2010 and now account for over half [52%] of all drug arrests in the United States, and marijuana possession arrests account for nearly half [46%] of all drug arrests. In 2010, there was one marijuana arrest every 37 seconds, and states spent combined over $3.6 billion enforcing marijuana possession laws.
The report also finds that, on average, a black person is 3.73 times more likely to be arrested for marijuana possession than a white person, even though blacks and whites use marijuana at similar rates. Such racial disparities in marijuana possession arrests exist in all regions of the country, in counties large and small, urban and rural, wealthy and poor, with large and small black populations.
