Vaporization
A method of cannabis administration that heats plant material or extracts to temperatures that volatilize cannabinoids and terpenes without combustion, reducing harmful byproducts.
In Depth
Vaporization occurs at 170–230°C, below the combustion temperature of cannabis (~230°C). This produces a vapor containing cannabinoids and terpenes with significantly fewer toxic combustion byproducts (carbon monoxide, polycyclic aromatic hydrocarbons, tar) compared to smoking. Vaporization bioavailability is similar to smoking (11–45%) with faster onset. Dry herb vaporizers heat the plant material directly; concentrate vaporizers heat extracts. Vaporization is increasingly recommended over smoking for medical cannabis patients.

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.
