It's far from the miracle drug its touted as...why else would the feds allow it for narcotic addiction treatment, out of the goodness of their hearts? Before its use as a treatment for addiction, bupe was classified as schedule V! I get migraines, but have never had them at the frequency I have since going on bupe and they are usually induced by allergens, never drugs, until this one. Bupe is made from a different alkaloid(thebaine)of the poppy than the more common opiates/opioids. It stimulates the mu recptor, but not nearly as much as morphine, codeine, etc. But it dissociates more slowly, comparatively, making it a good candidate for preventing withdrawl without much euphoria(though as someone mentioned) it is a pretty good painkiller, apperantly not for headaches though!
