H4CBD — cannabinoid profile

H4CBD (Hydrogenated CBD, Tetrahydrocannabidiol) is a cannabinoid that occurs naturally in cannabis or is derived from its precursors. Molecular formula C₂₁H₃₄O₂, molar mass 318.5 g/mol. Among the 100+ identified cannabinoids, H4CBD belongs to the mildly psychoactive group. This page consolidates current knowledge on chemistry, occurrence in cannabis, receptor action and Swiss legal status — for information only.

H4CBD · C₂₁H₃₄O₂ · 210 °C · mildly psychoactive · in Switzerland: legal grey area.

Chemistry

Chemically, H4CBD is a terpenophenol (meroterpenoid). H4CBD is produced industrially by hydrogenating both double bonds of CBD (catalyst Pd/C, H₂). Boiling point ~210 °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, H4CBD is produced in the trichomes of the female flower. Typical concentrations: in der Pflanze nicht signifikant; semi-synthetisch aus CBD. Content depends on genetics, light spectrum, harvest timing and storage. Specific strains are linked dynamically below from our strain database.

Swiss legal status

H4CBD sits in a Swiss legal grey zone. Not explicitly banned, but Swissmedic has hardened its stance on semi-synthetic cannabinoids; future scheduling is possible. Commercial sale lacks a solid legal basis. Swiss legal note: cannabis with ≥ 1 % THC is a narcotic under the Narcotics Act. CBD products below 1 % THC are legal.
