Cannabis can be confusing, to say the least. The United States does not yet have legal weed at the federal level, and state laws on pot differ wildly, even in states where recreational cannabis is legal.

At GreenState, we’re doing our best to keep you updated on the latest in cannabis law in the US. That’s why we partnered with Legalization Nation, an explanatory comic strip by Box Brown that provides a perspective to consumers and patients on the complexities of the emerging legal cannabis industry.

Legalization Nation talks about cannabis from a ground-level perspective, addressing issues like the traditional market, patients’ rights, corporate advantage, and more, and compares state cannabis legalization policies to help make sense of a daunting landscape through a familiar medium.

This week, Box Brown discusses a new Philadelphia public transit campaign spreading weed stigma.
