Flying across states like it's normal — but cannabis laws still change every 10 miles.

America has a single flag and 50 different cannabis rulebooks. You can take off in a recreational state, land in a medical-only state, connect through an illegal state, and rent a car in a fourth state with its own DUI thresholds — all in one day. The patchwork is exactly why U.S. cannabis travel needs a small amount of homework: possession limits, purchase caps, public consumption rules, and reciprocity for medical cards all shift the moment you cross a line on the map. A quick read of the state-by-state breakdown turns the confusion into a checklist.
