There has been a flurry of business activity this year by several multibillion-dollar companies in the alcohol and tobacco space looking to capitalize on opportunities in legal marijuana. The cannabis industry has seen an influx of liquor companies such as Constellation Brands, Molson Coors Brewing, Heineken’s Lagunitas Brewing as well as tobacco firms Pyxus International (formerly Alliance One International), Altria Group (which owns Marlboro maker Philip Morris USA and is an investor in alcohol giant Anheuser-Busch InBev) and Imperial Brands.
