Best Practices for Employers

  • Develop a comprehensive marijuana policy that accounts for current laws in each state where your company operates.

  • A zero-tolerance policy for marijuana may not be possible, depending on your state’s laws. However, the best marijuana policies will:

  • Prohibit workers using marijuana in any form while at work.

  • Prohibit workers from being under the influence of marijuana when they report for work.


  • Partner with an attorney to review your policy and provide feedback. Make sure the attorney understands state marijuana laws and is up-to-date on marijuana-related case law.

  • Outline specifics of drug testing if it is a part of your marijuana policy.

  • Make sure your policy describes the conditions under which testing will occur (e.g., ongoing periodic random testing, any time impairment is suspected, or only after a crash), the threshold that will constitute impairment, and the consequences of a positive test.

  • Seek out and use a medical professional with training in interpreting THC drug tests.

  • Warn drivers that Cannabidiol (CBD) product labeling is not regulated. Labeling is frequently inaccurateexternal icon. Consumption of CBD products with significantly higher levels of THC than what is on the producer’s label could result in a positive drug test.


  • Provide access to support for employees with drug problems, either through in-house programs or referrals to local resources.

  • Educate drivers on:

  • The effects of marijuana and other drugs on safe driving and cognitive abilities.

  • The details of your company’s marijuana policy, including special considerations for the state or states where they work.

  • Similar impairments that can result from fatigue, medications, and certain medical conditions.


  • Train managers and supervisors on:

  • The specific responsibilities of managers/supervisors outlined in the policy.

  • How to recognize and document signs of impairment.


  • Monitor the relevant state marijuana laws and any improved methods for determining impairment. Update your policies as needed.
