Workplace Drug Testing Issues – Iowa State Laws
Use caution when drug testing in Iowa, have a written policy and follow Iowa laws carefully.
These categories do not affect DOT-regulated drug testing. Government employers should always call for potential additional restrictions on employee drug testing.
On May 9, 2017, Iowa Governor Harry Branstad signed into law an Act allowing private sector pre-employment drug testing using hair samples. This law went into effect on July 1, 2017. Prior to the passage of this law, Iowa only allowed private sector testing for drugs of abuse through urine, blood, and oral fluid.
On 02/26/2021 Iowa passed a law making it a criminal offense with penalties for cheating or defrauding a drug or alcohol test. See House Bill 283.

A written policy is required for workplace drug testing.
Intoxication Defense – Iowa Code Ann. 85.16
Unemployment Denial – Iowa Code Ann. 96.5(2)
Intoxication Defense – Denial of Workers Compensation Claim – States vary in their willingness to allow employers to use an injured worker’s intoxication as a defense against a claim for compensation. State laws’ intoxication defenses generally fall into one of three rough categories: defenses that do not depend on causation; defenses that require some form of proximate causation between intoxication and injury; and defenses that require that intoxication be the sole cause of injury. Always check with your insurance company and your attorney when you have a refusal or positive post-accident test after an injury.
