I agree with you. I had a drinking problem. I tried AA and other methods to stop drinking and they never even came close to helping. One day I discovered that for me, alcohol and opiates did not mix and made me violently ill without fail.
Using that to my advantage, I became addicted to opiates, knowing I couldn't drink while on them. It broke my mental addiction to alcohol a few months after the physical addiction was gone. Breaking the mental addiction was the critical part. Once I knew I no longer wanted to drink, I knew it no longer had control over me.
Breaking the opiate addiction afterwards was easy because I never really wanted to do it in the first place. I never had the mental addiction. I just drank until the opiate physical addiction was gone, then stopped drinking because I already didn't want to, it was only a tool being used.
I don't recommend anyone try this method though. It very likely will kill anyone who attempts it. I wanted to share because for me, it confirms what you said, forcing an addict to get 'clean' will only make it harder for them to do so. In my opinion.
