Prospective relationships between drug problems and work adjustment in a community sample of adults.

The prospective relationships between drug problems and work adjustment (e.g., job instability, job satisfaction) were examined in a community sample of 470 adults. Polydrug problems (alcohol, marijuana, and cocaine problem drug use) were both predictors and consequences of work adjustment. In partial support of the impaired functioning theory, polydrug problems predicted reduced job satisfaction 4 years later. Supporting the work-related strain theory, early job instability predicted polydrug problems 4 years later. In support of the theory of general deviance, low social conformity predicted later job instability. Finally, supporting social support theory, early support for drug problems reduced polydrug problems and increased job satisfaction 4 years later.
