Drug abuse is often a key factor in criminal behavior. Unfortunately, locking up drug abusers doesn't stop crime, and it doesn't stop drug addiction. Pennsylvania recognizes that fact and has set up Drug Courts throughout the state. In the federal system, drug treatment is available for many inmates through the Bureau of Prisons.
Recently President Obama issued 95 commutations and 2 pardons. Most of these clemency grants were for drug-related offenses. Many of the crimes involved cocaine.
