How to Acquire a Minnesota Cannabis License

The Minnesota cannabis program is online and rolling out slowly. Too slowly, in this writer’s humble opinion. That said, a handful of tribal dispensaries have been operating since 2023, and adult use sales at non-tribal shops began in September 2025. To the good, sales are ticking up each month. In April, the Office of Cannabis

Marijuana Rescheduling and Income Tax

The DOJ Final Order on marijuana rescheduling dropped last week. Acting Attorney General Todd Blanche ordered that “FDA-approved drug products containing marijuana, as well [as] marijuana in any form covered by a state medical marijuana license, be placed in schedule III of the CSA.” The Order went further than many of us anticipated.

CBD, Medicare, and the New FDA Enforcement Memo

We got a new FDA cannabis enforcement memo on Wednesday, April 1, regarding “hemp-derived CBD research in medical research models.” The general thrust is FDA’s assurance that it won’t interfere with a new federal initiative, which covers up to $500 of hemp-derived products for eligible Medicare patients.

Oregon’s New Cannabis Laws: 2026 Edition

IRC 280E Still Applies to Your Marijuana Business, Unfortunately

In the last year or two, we have seen a growing number of marijuana businesses take the position that IRC 280E no longer applies to them. Some of these businesses have taken that position in consultation with lawyers and CPAs. This shift in strategy predates Trump’s Executive Order of December 18, 2025, to reschedule marijuana

Oregon Cannabis 2026: Legislative Forecast and Report

Oregon’s 2026 legislative session began last week on February 2. The biennial “short session” will last but 35 days, and focus on budget shortfalls, transportation and housing—which is to say that cannabis is not a priority. That said, of the 300 or so introduced bills, there are four cannabis-related submissions. That’s where I come in.

15 Years Lawyering in Oregon Cannabis, and Beyond

Last month, we hosted a webinar on federal cannabis law and policy in 2026. While things are not where we’d like them to be, it’s amazing to consider everything that has happened over the years. From a lawyering perspective, it’s almost unbelievable. I have worked as a business lawyer in the cannabis industry for over
