Colorado Workplace Saliva (Oral Fluid) Drug Testing Law
How Colorado treats oral fluid (saliva) drug testing in the workplace — the statute, its current status, and what that means for employers building or updating a testing program.
Status: Open / Permissive
Statute and status in Colorado
Statute / authority: C.R.S. § 24-34-402.5 · No mandatory testing law
No mandatory workplace drug testing law. Oral fluid fully permissible. Colorado protects off-duty cannabis use for non-safety-sensitive positions, but testing itself is not restricted. Safety-sensitive employers (transportation, mining) have full discretion.
What this means for employers in Colorado
Colorado has no statute restricting the specimen an employer may test, so saliva testing is permitted under general employment law. Keep a written policy, apply it consistently, and confirm non-negative screens at a laboratory.
