Do you think a lot of people go to methadone clinics to use the medicine for pain instead of addiction?

I have heard several people say that they really need methadone for pain, because their doctors would not give them strong enough medicine for pain, so they had to "fake" addiction in order to get the medicine at the methadone clinics. Some say that they are still dependent, but they still need it for pain also.
I know all about methadone, so I am not really asking about it or comments on it. I know the reason people go to the clinics is to get off the more dangerous street drugs. I know some people were going to doctors and the doctors had them on opiate medication for a while, and then took them off, which I didn't really understand why they put them on it to begin with, if they are just going to take them off. So they still need pain medicine and the only way to get it would be to go to the methadone clinic if they cannot find another doctor to keep them on it. So I have heard several say that although they were dependent, they still need the methadone for pain. So I was hoping maybe the ones that are in this situation would tell me. I know that methadone does not make a person high like the street drugs.
I was really wondering since I had heard some say that, and hoped maybe I would get answers from the methadone clients, but it's okay if you want to give your opinions, as long as you know enough about it, and not just what someone tells you, because I have heard all kinds of different stories. I know that some doctors where I live, do not like to prescribe opiate pain medicine, and I can understand why, if the pain is not real bad, and isn't an on-going condition. But what I am asking is do you, or do you know someone to whom the doctor was prescribing opiates for an on-going severe condition, and then cut them off for fear of dependency (which seems like it would be too late anyway after a month or so) and that person went to a methadone clinic and just said that they were dependent , which was probably true, but the main reason was that they needed something to ease the severe pain?
