On December 20, 2018, the President of the United States signed the 2019 Farm Bill, which authorizes states to implement a hemp (= industrial hemp) program under the oversight of the U.S. Department of Agriculture, including removal of hemp from the definition of marijuana - a Schedule I drug. This change will allow commercialization of hemp as a legitimate agricultural crop separate from marijuana. Marijuana is still illegal to grow in Indiana.
On March 26, 2014, Governor Mike Pence signed the "Industrial Hemp" bill into law, IC 15-15-13, authorizing the Office of Indiana State Chemist & Seed Commissioner to obtain the necessary permits and authorizations for and production and regulation of industrial hemp in Indiana.
