Cannabis law in North America is a patchwork, and this week Four20 Post is launching an interactive map to make sense of it. The map shows every US state, every Canadian province and territory, and all 32 Mexican states on a single tile layoutEach tile is color-coded by legal status: recreational and medical, medical only, low-THC or CBD only, or no program. Mexico gets its own category, because personal use there is decriminalized but no legal retail market exists. Tap any tile to see a short summary of that region’s rules.
The map goes beyond the headline legal status. A dot on a tile means local governments can ban cannabis businesses even where the state or province has legalized, which is why a “legal” state can still have large areas with no dispensaries. In Colorado, California and Oregon that opt-out power often sits with counties. In Michigan and New Jersey it sits with cities and towns, and in Ontario a small share of municipalities opted out of physical stores.
A toggle at the top switches to a second layer for hemp-derived THC products such as delta-8 and THC drinks, which follow different rules from marijuana and are heading toward a federal showdown. Congress has pushed the start of a national ban on most intoxicating hemp products to December 11, 2026, and the map notes that date in the hemp view.
A few caveats come with the launch. The marijuana layer reflects 2026 reporting on state and provincial programs, but cannabis law changes quickly, especially around elections. The hemp categories are our best reading of conflicting sources, since states often treat delta-8, edibles and beverages differently. The local opt-out notes are approximations, not an audited county-by-county count, because most states don’t publish one in a consistent form. We’ll update the map as laws change. If you spot an error or have a source for a more precise local figure, send it to us so we can correct it.
