i never had a clinic put me on methadone cause i never had a herion addiction,for that matter i never even messed with herion,i have a buddy who gets abunch of biscuits every month and he throws me 12 or 15 of them,im using methadone now for pain,some weeks i wont use any but some weeks ill break a biscuit into 4 parts and take a piece of the pain is really bad.i dont think its addicting at all imo cause i can go weeks without it and feel mentally ok.on the other hand i had a vike and perc problem awhile back and those babies are addicting as hell,i hurt my back years back in an accident and the doctor kept prescribing them for me and before you know you start to enjoy them,they are bad news
