Illegal when derived from marijuana plants except for registered epileptic patients, providing it contains less than 0.3% THC. While widely available, the state Attorney General released a statement in December of 2019, that CBD remains illegal.


Iowa, a Midwestern U.S. state, sits between the Missouri and Mississippi rivers. It’s known for its landscape of rolling plains and cornfields. Landmarks in the capital, Des Moines, include the gold-domed, 19th-century State Capitol Building, Pappajohn Sculpture Park and the Des Moines Art Center, noted for its contemporary collections. The city of Cedar Rapids’ Museum of Art has paintings by native Iowan Grant Wood.
