In 2010, a federal judge sentenced Tony DeJohn to life plus 10 years on a nonviolent marijuana charge. Because it was DeJohn’s third marijuana-related conviction, the judge was required by law to impose the maximum penalty available. He was just 31 years old. Eleven years later, DeJohn, who is from Upstate New York but had been locked up in high-security facilities in Pennsylvania, Kentucky, and Colorado, was granted clemency by then-President.
