More than 600 people are getting involved in the hemp industry this year in Michigan. The Michigan Department of Agriculture and Rural Development issued 600 industrial hemp licenses to farmers during four day-long licensing events held at the end of April.Though industrial hemp is now legal in Michigan and the U.S., the federal government is still developing the rules for a national hemp program. Rather than wait until 2020 to start the industrial hemp industry in Michigan, officials decided to launch a pilot program using a provision in the 2014 U.S. Farm Bill.
