Sulbutex - Buprenorphine...
The heroin they use is a fast acting opiate whereas buprenorphine
is slow acting...
Slow counters fast, the patient may still get his 'dose' but in
very low amounts, so that he can gradually taper his addiction off,
by continuing this medication over a long time.
With improvement, his dose will be reduced over time, and then
finally ceased. Some abuse this drug and sell it...
