HHC — cannabinoid profile

HHC (Hexahydrocannabinol) is a cannabinoid that occurs naturally in cannabis or is derived from its precursors. Molecular formula C₂₁H₃₂O₂, molar mass 316.5 g/mol. Among the 100+ identified cannabinoids, HHC belongs to the psychoactive group. This page consolidates current knowledge on chemistry, occurrence in cannabis, receptor action and Swiss legal status — for information only.

Chemistry

Chemically, HHC is a terpenophenol (meroterpenoid). HHC is produced by hydrogenating the double bond of Δ9-THC (industrially); no significant biosynthesis in the plant. Boiling point ~155 °C. It is lipophilic, sensitive to heat and light, and slowly oxidises in air. Analytically it is quantified by HPLC (acid form) and GC-MS (neutral form after decarboxylation) and appears on every modern Swiss batch COA.

Occurrence in cannabis

In cannabis, HHC is produced in the trichomes of the female flower. Typical concentrations: in Naturblüte in Spuren; kommerzielle HHC-Produkte werden aus CBD synthetisiert. Content depends on genetics, light spectrum, harvest timing and storage. Specific strains are linked dynamically below from our strain database.

Swiss legal status

In Switzerland, Swissmedic added HHC to the narcotics schedules in 2023 due to abuse potential. Trade, import and possession without authorisation are punishable. Swiss legal note: cannabis with ≥ 1 % THC is a narcotic under the Narcotics Act. CBD products below 1 % THC are legal. Effect descriptions are informational and are not therapeutic claims.
