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’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.
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
It’s MLK Day once again. I have written an MLK Day post on this blog for nine consecutive years. The theme of all these posts is that cannabis is a civil rights issue, and that Dr. King would have advocated for ending marijuana prohibition based on that fact. Each year, I have demonstrated with facts

For now, though, let’s cover everything that happened in 2025—which is a lot. Sales and market data According to OLCC data, total sales from
On Monday, the U.S. Supreme Court denied certiorari in Canna Provisions, Inc. et al. v. Bondi, a high-profile lawsuit that challenged the constitutionality of the federal prohibition of intrastate (and not interstate) cannabis activity. The denial offered no reasoning; nor was it accompanied by dissents or concurrences from any of the justices—all of which is
Yesterday afternoon, the Washington Post and other sources reported that President Trump is expected to issue an executive order directing federal agencies to reclassify marijuana, to Schedule III. That’s some sexy reportage, although WaPo’s sources cautioned that “Trump could still change his mind” and “[a] White House official said no final decisions have been made
Last month, I gave my big-picture thoughts on the intoxicating hemp products ban under P.L. 119-37, concluding that enforcement was an open question. That question has started to pick up steam, particularly following a Congressional Research Service report published on December 3rd. The CRS report provides: …it remains unclear if and how federal law enforcement
Federal cannabis policy has always been a mess. When I say “always”, I’m looking back 90 years or so, beginning with the Marihuana Tax Act of 1937, then skipping ahead to the Controlled Substances Act, the Rohrbacher-Farr Amendment, the 2014 Farm Bill, and the 2018 Farm Bill—not to mention the various awkward and occasionally incoherent
