Evaluation of the 1996 Washington State Drug-Free Workplace Discount Act

The Foundation's Substance Abuse Policy Research Program was designed to provide support for investigators to conduct policy research on a variety of subjects directed at helping the country reduce the harm caused by substance abuse.The problem of workplace substance abuse continues to receive wide attention. Although the precise magnitude remains uncertain, there is concern that workplace substance abuse in some industries and occupational settings has a major effect on worker productivity, as well as on worker health and safety. Currently, little reliable, scientific information exists on the effects of drug-free workplace programs. In 1996, the Washington State Legislature passed the Drug-Free Workplace Discount Act (S.B. 5516). The Act established a statewide initiative aimed at reducing the risk of workplace injury and at improving worker health and safety by encouraging employers to adopt a comprehensive drug-free workplace program. The purpose of this project is to conduct a comprehensive evaluation of the Washington State Drug-Free Workplace Act. The evaluation will employ a quasi-experimental (matched-group) design to perform a series of analyses that compare changes in occupational injury rates and associated medical costs, time-loss (wage replacement) payments, and related measures between companies with Drug-Free Workplace programs and companies without such programs. As part of the evaluation, a process evaluation will be performed to document employers' experience and effectiveness in implementing the Drug-Free Workplace program. The findings of the evaluation should help inform policy development and planning within the field of workplace substance abuse prevention, thereby improving prevention and treatment efforts.
