If you have legal requirements for a drug-free workplace policy and program and comply with those requirements, you will reduce the chances that your organization will experience legal issues. First, you will be meeting the requirements of the law. Second, you will be able to reduce drug-related accidents and the liability issues and lawsuits that can arise from such accidents.
In addition to meeting the legal requirements, consider putting in place a drug-free workplace policy and program that addresses the specific issues and needs in your workplace. Issues and needs can be identified by assessing your workplace. This approach increases the likelihood that you will achieve positive results in the form of reduced drug use and related problems.
