For years doctors have tried to understand the chemistry behind addiction and relapse, and now they think they may have found the culprit.
Doctors say alcoholics drink more to feel better and that's what increases the risk of relapse.
The same goes for cocaine addicts. Scientists are working on two different treatments to help treat that type of addiction, and avoid a relapse with a drug that works much in the same way. The drug is called methadone, and it has helped heroin addicts stay clean. Scientists say this latest discovery is just a piece of a big puzzle to solve the mystery of addiction, they say most recovering addicts require emotional and spiritual support as well.
