NEW YORK (MainStreet) — If you want to start a marijuana business but have no idea how to go about it, then Cannabis Career Institute is the place to go. CCI Founder Bob Calkin tells TheStreet's Debra Borchardt what his school teaches budding "ganja-preneurs." It seems like typical small business advice, yet the product is illegal and that's what makes this class so unique. The marijuana industry has many career paths to choose from including dispensaries, bud trimmers and growers.
