Suboxone contains buprenorphine and naloxone and is used to treat opioid addiction. Meth addiction can also be treated with suboxone. Infact, suboxone can be used to treat not only opioid addiction but also for alcohol, meth and other stimulant addiction. Other medicines like provigil and antabuse can also be used.
No one should ever take suboxone unless they have a high tolerance for opioid drugs, because it can kill you.
