There are substance abuse programs offered in or near Etna which service both methadone and buprenorphine clients only, medications which are dispensed in what is known as opioid maintenance therapy. Methadone is a full opioid agonist just like heroin, and buprenorphine is a partial agonist, meaning the same neural receptors which cause an individual to feel high from heroin or prescription pain killers are activated by these two drugs so therefore an opioid addicted client will ideally not engage in drug seeking behavior and won't experience cravings and withdrawal. There are dangers with drug interactions, side effects, and even addiction and overdose with both methadone and buprenorphine, which is why they are heavily controlled and can only be dispensed in a clinical setting.
Buprenorphine and methadone clients are on these medications regularly so they don't experience cravings, withdrawal, etc. but ideally at a dosage which isn't at the same time making them feel euphoria. Euphoria is possible at a high dosage, more significantly with methadone than buprenorphine. At clinics that treat methadone and buprenorphine clients only, actual rehabilitation activities and therapies are generally limited beyond managing the medication and the main treatment objective is to manage the physical symptoms of their dependence. Some clinics do provide a limited amount of counseling and therapy as auxiliary treatment, and it is recommended and encouraged.
