Federal drug testing rules are administered by:

  • the Drug-Free Workplace Act
  • the U.S. Department of Transportation (DOT)

The Drug-Free Workplace Act covers federal government agencies, federal contractors with contracts or purchase orders totaling $100,000 or more, and recipients of federal grants. The Act does not require alcohol or drug testing, but testing is authorized as a means to maintain a drug-free workplace.

The DOT drug testing rules cover employers in the air, rail, trucking, and mass transit industries, and employers with operations otherwise covered by DOT. These rules require the testing of employees in safety-sensitive positions for alcohol and illegal drug use.

In addition to federal laws, there are also state laws that regulate drug testing in the workplace. There are currently 15 states with no pre-employment drug testing laws, meaning their policies are effectively the same as the federal law. These states include Arkansas, Colorado, Indiana, Kentucky, Louisiana, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, North Dakota, Pennsylvania, Texas, West Virginia, Wisconsin, and Wyoming.
