 Pentazocine lactate (CAS NO.17146-95-1) is a CYP450-2D6 inducer that increases the degree of conversion of codeine to morphine (the active metabolite of codeine - a prodrug with no intrinsic activity), in vivo, by approximately a factor of three, increasing the average degree of codeine metabolized to morphine from 10% to 30%  - while synergistically adding to the depressant effects of the codeine.
The mu-opioid-antagonist naloxone was added to preparations containing pentazocine, and the reported incidence of its abuse has declined precipitously since. A more recent recreational route is pentazocine combined with methylphenidate (Ritalin) via the oral route, insufflation or mixed intravenously.

A poison by intraperitoneal route. Human systemic effects. A human skin irritant. When heated to decomposition it emits toxic vapors of NO_x.
