What’s in it

AI summary Iowa would stop classifying psilocybin and psilocyn as Schedule I controlled substances. This change affects how these specific substances are categorized under state drug laws.1

Read the official explanation

This bill removes psilocybin and psilocyn from the list of substances classified as schedule I controlled substances under Iowa’s uniform controlled substances Act (Code chapter 124). Under Code section 124.203, a substance that has a high potential for abuse and has no accepted medical use in treatment in the United States or lacks accepted safety for use in treatment under medical supervision may be classified as a schedule I controlled substance under Code chapter 124.

Why it matters. Psilocybin and psilocyn would no longer be classified as schedule I controlled substances in Iowa. This change affects how these substances are regulated under the state's uniform controlled substances act.2
