How Many People Are Incarcerated for Marijuana?Over 1 million people are incarcerated in the U.S. for marijuana, most for simple possession. This is more than those who are in federal prison for murder, rape, and other violent crimes on a federal level. Over 800,000 of these include African Americans, even though Blacks and Whites use the drug at similar rates.
According to a recent study by the American Civil Liberties Union, the prison population for marijuana use was 1,561,013 from 2001 to 2010. The study did not look at pre-2001 data, so the actual number of marijuana-related arrests is likely much higher than their reported figure.
