Trichomes
/TRY-komz/
Microscopic glandular structures on the surface of cannabis flowers and leaves that produce and store cannabinoids, terpenes, and flavonoids.
In Depth
Cannabis trichomes are the primary site of cannabinoid and terpene biosynthesis. Three types exist: bulbous (smallest, ~15μm), capitate-sessile (medium), and capitate-stalked (largest, most abundant on flowers, primary source of cannabinoids). Trichome density and morphology are key indicators of cannabis potency. Trichomes are harvested to produce concentrates (kief, hash, rosin). Trichome development is influenced by genetics, light intensity, temperature, and harvest timing.

Decarboxylation
The chemical process by which a carboxyl group (COOH) is removed from a molecule, releasing CO₂. Converts inactive cannabinoid acids (THCA, CBDA) into their active forms (THC, CBD).
THCA (Tetrahydrocannabinolic Acid)
The acidic, non-psychoactive precursor to THC found in raw, unheated cannabis. Converted to THC through decarboxylation.
CBDA (Cannabidiolic Acid)
The acidic precursor to CBD found in raw cannabis. Converted to CBD through decarboxylation.
Lipophilicity
The tendency of a molecule to dissolve in fats, oils, and non-polar solvents rather than water. Cannabinoids are highly lipophilic.
Myrcene
The most abundant terpene in most cannabis strains. Produces an earthy, musky aroma. Proposed to enhance cannabinoid absorption and contribute to sedating effects.
