Although there are a number of methods that could be used to correct opioid addiction, treating it medically is one of the most effective ways.

Added to that, methadone is completely safe if taken in compliance with the directives from a medication-assisted treatment expert. Ideally, methadone should only be taken under the supervision of a health provider because its misuse could be dangerous to health. Some methadone clinics in Kentucky do not stop at providing doses of methadone but they also offer additional social and medical services. Methadone maintenance lasts as long as the health provider thinks it is needed. There is no limit to duration.
