From the Document: "Among all state and federal prisoners (1,421,700), nearly 4 in 10 (38%) reported using drugs and 3 in 10 (30%) reported drinking alcohol at the time of the offense for which they were serving a sentence. Statistics in this report are based on self-reported data collected through face-to-face interviews with a national sample of state and federal prisoners age 18 or older in the 2016 Survey of Prison Inmates (SPI). Nearly two-thirds (64%) of state and federal prisoners reported using at least one drug in the 30 days prior to arrest for the offense for which they were serving time. Among state and federal prisoners who were not incarcerated for the entire 12 months prior to admission to prison for the offense for which they were serving a sentence (916,900), nearly half (47%) met the 'Diagnostic and Statistical Manual of Mental Disorders', Fourth Edition (DSM-IV) criteria for substance use disorder in the 12 months prior to admission to prison."
