Northern Michigan University has launched a new program in its chemistry department: a medicinal plant chemistry program. The program is the first degree of its kind at a four-year undergraduate college. The legal marijuana business employs between 165,000 and 230,000 Americans. Brandon Cangield, an associate chemistry professor at NMU, told CBS Detroit, "The need for this is so great. You go to some of these cannabis industry conferences and everyone is talking about how they need labs, they need labs." Students will take classes in chemistry, plant biology, and business entrepreneurship. Michigan voted to legalize medical marijuana use in 2008.
