BALTIMORE - Organizations such as Sheppard Pratt Health System can now treat more than three times as many heroin addicts with the highly effective drug buprenorphine, thanks to a move by Congress to amend the Controlled Substances Act. The changes, approved Dec. 8, raise from 30 to 100 the number of patients a clinic or hospital can treat with the drug. That is a boon to drug abuse counselors and to addicts in the Baltimore region, said addictions educator Michael Gimbel, of Sheppard Pratt. "This is a very important piece of legislation. It will immediately allow us to treat more heroin and opiate addicts. Buprenorphine seems to be a very effective alternative to methadone in treating addicts." [continues 60 words]
