Approximately a half-million people are in prison or jail for a drug offense today, compared to an estimated 41,100 in 1980—an increase of 1,100 percent.2 Drug arrests have tripled since 1980. As a result, more than 31 million people have been arrested for drug offenses since the drug war began.3 To put the matter in perspective, consider this: there are more people in prisons and jails today just for drug offenses than were incarcerated for all reasons in 1980.
