SHERIDAN, IL - NOVEMBER 14: Hasan Cunningham listens to speakers during a self-help group session focusing on life outside of prison at Sheridan Correctional Center November 14, 2005 in Sheridan, Illinois. A dedicated center for the treatment of inmates with drug and alcohol abuse problems, the state opened Sheridan in January 2004 to combat a recidivism rate of 54% in its penal system. Nearly 69 percent of all inmates in the Illinois prison system are serving time for drug or alcohol related offenses. The recidivism rate for prisoners who have served time at Sheridan is only 7.7 percent. Cunningham, whose drugs of choice were marijuana and alcohol, is nearing the end of a 4 year sentence for drug conspiracy. It is his fourth time in prison. (Photo by Scott Olson/Getty Images)
