IA HF609

Amends Iowa's Religious Freedom Restoration Act (Code chapter 675) to explicitly include the use of psychoactive substances, including psilocybin and peyote, in religious or spiritual ceremonies as a protected "exercise of religion"

Prohibits state action from substantially burdening a person's religious use of controlled substances unless the government demonstrates a compelling governmental interest and uses the least restrictive means to further that interest

Specifies that Iowa's controlled substances law (Code chapter 124) cannot be used to burden religious exercise without meeting the compelling interest and least restrictive means tests

Expands the definition of "exercise of religion" to cover religiously-motivated substance use regardless of whether such use is compulsory or central to a larger system of religious belief
