Also of interest, nearly half of the total studies reporting successful nonabstinent outcomes were conducted outside the United States.

A second point of interest is that although successful nonabstinent outcomes have repeatedly been referred to as rare occurrences, a review of the literature presents a different picture.

Furthermore, abstinent cocaine users showed greater fronto-central late LPPs to cocaine picturres that the other two groups, whereas the nonabstinent cocaine users exhibited lower LPPs to positive and negative pictures than abstient users and controls.
