 | | In the brains of addicts, methadone prevents heroin or morphine from interacting with receptors for natural painkillers called endorphins, blocking the effects of the addictive drugs and reducing the physical cravings. |
 | | Supporters point out that methadone maintenance, being oral, breaks the dangerous ritual of intravenous injection, that it is legal and eliminates the addict's need to engage in crime to pay for drugs, and that it gives addicts a chance to reevaluate their lives. |
 | | The increase in methadone abuse was apparently caused by heroin and oxycodone (OxyContin; a prescription painkiller) addicts using methadone when they could not get other drugs, as well as by an increase in the number of so-called recreational drug users who were abusing methadone. |
