Welcome back to Higher Law, our weekly briefing on all things cannabis. I’m Cheryl Miller, reporting for Law.com from Sacramento.

This week we’re looking at:

  • Law firms’ links to a pot-prohibition group.
  • A weed-and-workers lawsuit filed against Walmart.
  • Perkins Coie’s work on a trade dress suit targeting Martha Stewart and Canopy Growth
  • Why marijuana companies can’t make enough money.
