Idaho Drug-Free Workplace and Employer Testing Considerations
Idaho does not permit recreational or medical cannabis, and Idaho employers may maintain drug-free workplace policies that include THC testing. DOT-covered positions are governed by federal testing rules regardless of state law. The right program depends on your workforce, industry, contract requirements, and written policy. We coordinate on-site or nationwide collection access so your team can apply the program consistently.

Questions from employers in this region
Do our Port of Lewiston vessel crew members need USCG testing?
USCG 46 CFR Part 16 applies to crewmembers on vessels subject to Coast Guard inspection. Coverage depends on the vessel and crew role, so confirm your status with your marine compliance contact or the Coast Guard. We coordinate compliant collection logistics for covered marine employers.
Can you test plant employees and CDL drivers under one Lewiston account?
Yes. CDL drivers can be managed in a DOT FMCSA program while plant, warehouse, and office employees follow your non-DOT policy. We make collection scheduling simple while maintaining the separate records each program requires.
Can a crew member test while working outside Idaho?
Yes. Our 8,500+ nationwide collection locations allow traveling drivers, contractors, and crew members to complete collections away from Lewiston while results flow back to your program.
