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.
