bupe (suboxone/subutex) is a partial agonist opioid, meaning it only effects certain parts of receptors for opiate addicts, some people can take subutex, suoxone everyay and literally lose all mental cravings for opiates, while some people still have powerful mental cravings for heroin, and stop taking suboxong, and do heroin, and go back to subs to avoid physical WD, alot of people use sub as a tool to use opiates and just take sub to not suffer WD..everyone is different, me i lost mental cravings for opiates on suboxone, once in awhile i would skip a day to enjoy heroin,but most part it helped. subs will help physical WD for the heaviest heroin addict, the mental part is hit or miss, but i ende dp sellling my subs to substitute to smoke crack, and by benzos. i wasnt responsible toh old a script. im on methadone now and literally the thought of opiates pass thru my head within seconds, i can care less about it, but since im being lowered down on my methadone i noticed i been thinking of heroin a lot, methadone helps ALOT, and u dont get high from it, i was on 130mg, i got kicked out da program for benzo use, im down to 60mg, starting to feel sick and thinking of doing heroin
