Coming Soon, State Laws for Workplace Drug Testing

Regulations for workplace drug testing are very important to maintain an effective and legal drug free workplace program. It is particularly important to pay attention to individual state laws regarding employer drug testing programs. Employers need to be concerned about limiting exposure to liability in a drug testing program.

A good drug testing program will go a long way toward addressing safety, OSHA compliance, ADA Compliance, performance and workers’ comp issues; having the right company policies, education programs and insurance coverage will go the extra step to protect you against potential lawsuits and financial liability. Many states have different laws regarding drug testing, check back to view the guidelines for drug testing in your state.

General Statute

Iowa law doesn’t require drug testing, nor does it encourage or discourage testing. The purpose of the State of Iowa’s private sector drug testing law—Iowa Code Section 730.5 (& Iowa Administrative Code Section 641)—is to enhance worker safety by creating workplaces that are free of drugs and substance abuse or misuse. Private sector drug or alcohol testing is optional in Iowa. However, employers who choose to test can do so only after developing and disseminating a written policy.
