Market status

The caveats that matter

  • ALL smokable/inhalable hemp flower is banned regardless of THC or THCA content — the ban is product-form based, not potency based
  • Hemp vapes, gummies, and beverages with hemp cannabinoids are also prohibited under DOH rules
  • Medical marijuana (329 card) dispensaries are the only lawful flower channel; no adult-use program

Enforcement, in practice

DOH administers a retailer/distributor registry and can embargo non-compliant products; inhalable hemp is treated as per-se illegal.
