5 times as many Whites are using drugs as African Americans, yet African Americans are sent to prison for drug offenses at 10 times the rate of Whites
African Americans represent 12% of the total population of drug users, but 38% of those arrested for drug offenses, and 59% of those in state prison for a drug offense.
African Americans serve virtually as much time in prison for a drug offense (58.7 months) as whites do for a violent offense (61.7 months). (Sentencing Project)"
