What I'd really prefer is that people don't get addicted to this stuff in the first place, or that serious measures are taken to get them off it. I'm not sure, though, how you detox someone and get them off drugs if they don't want to.
I think the will to quit is
the most important aspect of ending addiction. There is help out there, especially since opioid addiction has become so widespread. Addiction can start with something as simple as over prescribing by a doctor after surgery. "I'll just finish this presciption and be done with it..." Uh-huh.
Some keep using because of chronic pain that doesn't respond to other drugs or therapy. Now buprenorphine with naloxone is being prescribed for opioid addiction. It has the pain killing power of opioids (for some), but has a threshold effect to limit the "high". It's main purpose is to block the cravings for opioids. Like opioid painkillers, it attaches to the same receptors in the body. For some, that is enough to ease the pain for a "normal" life.
