"Human anecdotal reports assert that a single administration of ibogaine reduces craving for opiates and cocaine for extended periods of time and reduces opiate withdrawal symptoms (Sheppard 1994; Mash et al., 1998; Alper et al., 1999). Studies also suggest that ibogaine attenuates drug- and ethanol induced behaviors in rodents. For example, ibogaine reduces operant self-administration of heroin in rats, as well as naloxone precipitated withdrawal in morphine-dependent rats (Glick et al., 1992; Dworkin et al., 1995). Administration of ibogaine decreases cocaine-induced locomotor activity and reduces cocaine self-administration in rats (Cappendijk and Dzoljic, 1993) and mice (Sershen et al., 1994)."
