It's crazy how someone would think just getting on medication

It's crazy how someone would think just getting on medication automatically takes the addiction away. I say this because I seen someone snapping out at OTP because they got on Methadone and can't stop getting high. He's actually mad because he thought once you take medication it's supposed to take it all away. He's also mad cause the courts won't throw his case out now that he's on medication. Some people should never do drugs to begin with.
