Suboxone (buphrenorphine) is a narcotic agonist/antagonist that is used for pain relief and opiate detoxification. Its opiate antagonist characteristics prevent users from getting as high as they would from other opiate drugs. However, it is addictive and should be used under the care of a physician who thoroughly understands the protocols for which it is intended.
There is a major storefront industry of quack doctors who claim to be experts in opiate detox using Suboxone. The giveaway is usually failure to accept insurance. Just ask them if they take insurance. If they say no, only cash, walk away.
