no suboxone is not a
form of
methadone, suboxone has actually two drugs
in it, the actually addiction aid is buprenorphine, which is a mixed agonist(like oxycontin, heoroin, vicodin, etc..) and naloxone, which is an opiate antagonist, which is used in suboxone to prevent IV drug abuse. If you take it correctly the naloxone is ineffective, but taken intravenously you will experience extreme withdrawals.
