Workplace drug testing laws by state
What each state allows when a private employer drug tests applicants and employees: written policies, random testing, and marijuana protections. Pick your state; every line links to the law.
Federal DOT rules cover only DOT-regulated jobs, such as CDL drivers. For every other job, state law decides whether an employer may test applicants, test employees at random, and act on a positive marijuana result. Some states bar random testing outside federal programs, as Vermont and Rhode Island do; others limit when and how employers test, as Minnesota and Connecticut do.
Each state page sums up that state's law in plain words, cites the statute for every line, and links the official source. Sixteen states also give a workers' comp premium discount for a certified drug-free workplace program; those pages link to the state's program. Use these pages to plan your policy, then read the law itself or ask a lawyer before you rely on them.

This page summarizes state law in plain words, with links to the law itself. It is not legal advice, and laws change: check the linked source, and talk to a lawyer about your own policy. Federal DOT testing rules are separate and override state limits for DOT-covered jobs. Checked October 2026.
