Supply chains are notoriously complex. And so is selling cannabis products in the US.

While the weed industry racked up more than $50 billion in sales last year, putting weed in the hands of consumers is a challenge. Each state is its own ecosystem and closed-loop system when it comes to regulations. That means when it comes to buying tools, products or plants across borders, if any of those things have to cross state lines, things get a bit tricky. It gets worse. Local governing bodies with regulations are able to create rules which supersede these state guidelines.

Keeping weed legit is hard. That's where a startup like Treum comes in. In the latest episode of our podcast, we explore how this blockchain company is helping the cannabis industry stick to the straight and narrow.
