Iowa

Iowa limits medical cannabis purchases to 4.5 grams of THC every 90 days, but patients with terminal illnesses or specific medical needs can request a waiver to increase this limit.

Even with a valid medical cannabis card, consuming cannabis in public places is prohibited.

Employers can conduct drug tests pre-employment, randomly (for safety-sensitive jobs), with reasonable suspicion, and post-accident. They must have a written policy detailing the procedures and consequences, which must be communicated to employees, and obtain written consent before testing.

*Remember, establishing robust documentation is a key risk mitigant for employers in states like the Iowa.

Safety-sensitive positions for drug testing are typically those where impairment could directly affect the safety and well-being of others and could pose significant risks to the safety of the individual, coworkers, or the public.

Test results must be kept confidential, employees can access and contest their results, and tests must be conducted by certified labs with the option for retesting if needed.
