Policies related to the War on Drugs have caused the number of people arrested, convicted, and incarcerated for drug-related crime to increase drastically. In 1980 there were 40,900 people incarcerated for drug offenses; by 2013, this number increased to 489,000. Considering that the vast majority of drug arrests are for possession, the criminal justice system is left to address high levels of substance abuse and addiction.
