Suboxone is just dope from a dope man in a lab coat. All suboxone does is switch addiction from opiates or opioids, to opioids. I've known more than a few people who were detoxing from suboxone say it's easier to kick heroin.
After I went to an inpatient treatment center and learned from the professionals there that kicking subs was way harder then heroin, and saw with my own eyes a few people there who were having a bitch of time.
I ended up telling her this, and strongly advised her to get back on heroin for a week and then kick...she followed my advice and thanked me for profusely as she tried the sub detox taper and couldn't make it work.
The proper protocol is to substitute the short-acting heroin for the longer half-life Suboxone. This stabilizes the blood levels, thereby eliminating inter-dose withdrawal symptoms.
The dose is supposed to be titrated to zero over a few weeks. Otherwise you'll just end up swapping on addiction for another.
It's a shame, because Buprenorphine is a really good medication when used properly.
Suboxone is a Godsend if you only use it to get over the initial w/d's
