Big tobacco, etc. have the experience and balance sheets to build a brand much faster than most of these cash-strapped weed companies with $20m yearly sales.  If cannabis production is not important, I'm betting on the incumbent big money players to build brands, not the startups.

Generally companies/conglomerates of that size prefer to buy brands and then leverage their distribution network, production efficiencies, etc. rather than risk building them themselves. See Pepsi, AB Inbev, Altria, etc.
