Workplace Drug Testing Laws for Missouri

Under Missouri law, there are few restrictions on employers who implement a drug-free workplace policy.

However, employers must follow the requirements under the Missouri Employment Security Law if an employer wants to deny unemployment benefits to employees who test positive for drugs or alcohol.

In December of 2018, Missouri passed statutes allowing the use of Medical Marijuana. The Medical Marijuana Act does not allow claims against employers for discharging or denying employment to employees who are under the influence of Marijuana.
