CBN — cannabinoid profile

CBN (Cannabinol) is a cannabinoid that occurs naturally in cannabis or is derived from its precursors. Molecular formula C₂₁H₂₆O₂, molar mass 310.4 g/mol. Among the 100+ identified cannabinoids, CBN 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.

CBN · C₂₁H₂₆O₂ · 185 °C · mildly psychoactive · in Switzerland: legal.

Chemistry

Chemically, CBN is a terpenophenol (meroterpenoid). CBN is not a direct biosynthesis product but forms via THC oxidation (time, light, oxygen). Boiling point ~185 °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, CBN is produced in the trichomes of the female flower. Typical concentrations: meist < 1 %, in gealtertem Cannabis höher. Content depends on genetics, light spectrum, harvest timing and storage. Specific strains are linked dynamically below from our strain database.

Swiss legal status

CBN is not specifically regulated in Switzerland; unproblematic as a component of a CBD product < 1 % THC. 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.
