What the record says

HHC capsules are prohibited synthetic cannabinoid products under 16-12-117(1). Montana enacted a categorical synthetic-cannabinoid ban via HB 948 (2023), codified at Mont. Code Ann. Section 16-12-117(1) and defined at 16-12-102(39). HHC is produced by hydrogenating hemp-derived CBD/THC -- a chemical synthesis in a laboratory -- so it is a 'synthetic cannabinoid' as a matter of the statutory definition, and the enforcing agency (Cannabis Control Division) names it explicitly. This is an EXPRESS statutory prohibition with an operative offense plus authoritative agency designation, satisfying the conservative bar for 'illegal.' All ten product forms are illegal because the prohibition reaches manufacture, processing, storage, and offer for sale regardless of form; even 'HHC flower' is hemp flower adulterated/infused with a synthetic cannabinoid, outside the 16-12-117(4) unadulterated-flower exemption.

Controlling language, verbatim

A person may not manufacture, process, store, or offer for sale a synthetic cannabinoid or a synthetic cannabinoid product. ... 'Synthetic cannabinoid' ... includes any cannabinoid produced artificially, whether from chemical synthesis or biosynthesis. [Montana Dept. of Revenue Cannabis Control Division guidance:] Look for products that contain or advertise common synthetic cannabinoids (e.g. delta-8-THC, delta-10-THC, THC-O-acetates, THCV, THCP, HHC, HHC-O-acetate, HHCP, and CBN.)
