    Nov 12, 2026: hemp-derived cannabinoid products, CBD and CBG included (topicals and pet products too), may be sold only to 21+; tier 1 products (synthetic or converted cannabinoids, THCA smokables, delta-9 edibles) go dispensary-only. Bulk CBG fits the new hemp definition, but whether extracted versus heat-converted CBG is reached by the manufactured-outside-the-plant clause is untested (see the CBG raw material row).
