People may find it difficult to control their reliance on opioid use even when it has negative effects because an attempt to withdraw could cause some disturbing reaction, part of which is pain and uncontrollable craving. Methadone minimizes both pain and craving. Also, its effects last longer in the body than the effects of opioids. Methadone makes the patient calm and it does not have negative effects. Although methadone could have some side effects that are not health-threatening if taken under the supervision of medication-assisted treatment health professionals. Methadone clinics are specialists, but some methadone clinics in Louisiana offer more services than the dispensing of methadone. Methadone is regulated to avoid misuse and diversion into the illicit market. Before the commencement of the opioid treatment program, methadone clinics are required to be certified by the Substance Abuse and Mental Health Services Administration.
