In order to measure manipulative tendencies among narcotics abusers, the Machiavellianism (Mach IV) Scale was administered to a sample of narcotics abusers in residential treatment. Obtained means and standard deviations were well within the range of values reported for non‐drug abusing samples. Examination of the retest‐reliability and validity of the present Mach IV scores confirmed the reliability of the scale. However, a three ‐person bargaining situation failed to validate Mach Scale scores, possibly due to constraints imposed by the institutional setting and for to the educational level of the sample.
