District of Columbia drug testing laws for employers
Washington, D.C. has no general drug testing law for private employers. Adults may legally possess marijuana, and employers may test applicants for marijuana only after a conditional job offer. A broader 2022 cannabis employment law has passed but is not in effect because it has not been funded.
Have a whole roster to keep current every month? DOT fleets: Pact's monthly DOT program, $25 a driver a month ($99 minimum), or $19 a month for an owner-operator. Nursing homes, hospice and home care: staff credential tracking, $10 a staff member a month ($250 minimum). First month free.

- You do not have to allow marijuana use or possession at work or at any time during employment (D.C. Code 32-931(b)(2)).
