Bioavailability
The proportion of a substance that reaches circulation and can have an active effect. It varies by product and method of use.
The cannabis glossary
Make sense of the language.
A practical reference for the words you meet in cannabis reporting, products, cultivation and cooking.
Cannabinoid
A chemical compound that interacts with cannabinoid receptors or related biological systems. THC and CBD are widely known examples.
Cannabis
A plant genus that includes varieties cultivated for cannabinoids, fiber, seed, and other uses.
CBD
Cannabidiol, a cannabinoid that is not typically intoxicating. Product composition, effects, interactions, and legality can vary.
CBG
Cannabigerol, a minor cannabinoid being studied for potential biological effects.
CBN
Cannabinol, a cannabinoid formed partly through the oxidation and aging of THC.
COA
Certificate of Analysis. A laboratory report that may show cannabinoid potency and screening results for contaminants.
Combustion
Burning plant material or concentrate to create smoke. Combustion produces byproducts that vaporization may reduce but not eliminate.
Concentrate
A product made by separating and concentrating compounds from cannabis plant material.
Cultivar
A cultivated plant variety selected for particular traits. It is often a more precise term than strain.
Decarboxylation
Heat based conversion of cannabinoid acids such as THCA into forms such as THC.
Dispensary
A regulated retailer authorized to sell medical or adult use cannabis under applicable law.
Dose
The measured amount of an active ingredient consumed at one time.
Duration
How long noticeable effects may last. Duration varies by dose, method, product, and individual.
Edible
Food or drink containing cannabinoids. Effects can be delayed and longer lasting compared with inhalation.
Endocannabinoid system
A signaling system involving receptors, endogenous cannabinoids, and enzymes that helps regulate multiple body processes.
Entourage effect
A hypothesis that cannabis compounds may interact to shape effects. The idea remains an active area of research.
Flower
The harvested flowering portion of the cannabis plant, commonly dried and cured for use.
Hemp
Cannabis defined under U.S. federal law by a delta-9 THC concentration threshold. State rules and product legality can still vary.
Home grow
Personal cultivation of cannabis at a residence where permitted. Plant limits and other restrictions differ by location.
Hybrid
A common market label for cannabis with mixed ancestry. The label alone does not reliably predict effects.
Indica and sativa
Traditional labels widely used in cannabis markets. They do not consistently describe chemistry or predict an individual experience.
Live resin
A concentrate commonly made from fresh frozen cannabis to retain more of the plant’s aromatic compounds.
Medical cannabis
Cannabis used through a medical program or under clinical guidance where permitted by law.
Onset
The time between use and the beginning of noticeable effects.
Rosin
A solventless concentrate produced using heat and pressure.
Terpene
An aromatic compound found in cannabis and many other plants. Terpenes contribute scent and flavor and may influence experience.
THC
Tetrahydrocannabinol, a cannabinoid associated with cannabis intoxication.
THCA
Tetrahydrocannabinolic acid, a precursor that can convert to THC through heat and time.
Tincture
A liquid extract typically measured with a dropper and used orally or under the tongue.
Trichome
A small resin producing structure on the cannabis plant that contains cannabinoids and terpenes.
Vaporization
Heating cannabis or concentrate to create an inhalable aerosol without intentionally burning the material.
