Cannabis glossary

Plain-language definitions of the cannabis terms you'll see on labels, menus, and across our guides.

Anandamide
One of the body’s own endocannabinoids, sometimes called the "bliss molecule," that THC partly mimics.
Autoflower
A cannabis plant that flowers automatically with age rather than by light schedule, thanks to ruderalis genetics.
BHO

Bioavailability
How much of a substance actually reaches your system, it varies a lot by consumption method.
Budtender
A staff member at a licensed cannabis store who helps customers choose products.
Calyx
The small teardrop-shaped pods that make up a cannabis bud, coated in resin-producing trichomes.
Cannabinoid
A class of active compounds in cannabis. THC and CBD are the best known of more than a hundred.
Cannabis ruderalis
A hardy, low-THC cannabis subspecies whose genetics give autoflowering strains their age-based flowering.
Cannabutter
Butter infused with decarboxylated cannabis, used as a base for homemade edibles.
CBC
Cannabichromene, a non-intoxicating minor cannabinoid being studied for anti-inflammatory effects.
CBD
Cannabidiol, a non-intoxicating cannabis compound often chosen for a calmer, clear-headed experience.
CBDA
The raw acid form of CBD found in the living plant, converted to CBD by heat or time.
CBG
Cannabigerol, a non-intoxicating "parent" cannabinoid that others form from; increasingly studied.
CBN
Cannabinol, a mildly intoxicating cannabinoid formed as THC ages, often associated with sedation.
COA
Certificate of Analysis, the lab report showing a product’s potency and contaminant screening.
Cola
The dense cluster of buds that forms along the main stem of a flowering cannabis plant.
Concentrate
Cannabis with plant material removed, leaving high cannabinoid levels, e.g. shatter, rosin, distillate.
Couch-lock
A heavy, sedating body high that leaves you happily stuck on the sofa, associated with some indica-leaning strains.
Cross-fade
Combining cannabis and alcohol, which amplifies impairment and is less predictable than either alone.
Cure
The slow post-harvest process of storing dried flower to develop aroma and smoothness.
Dab
A small dose of concentrate vaporized at high heat, potent, and not a beginner’s method.
Decarboxylation
Heating cannabis to activate THC, why raw flower must be heated to have an effect.
Dispensary
A cannabis retail store. In Canada, only provincially licensed dispensaries are legal.
Distillate
A highly refined, very high-THC extract stripped of terpenes; common in vape carts and edibles.
Edible
A cannabis-infused food or drink. Slow to take effect (up to 2 hours) and longer-lasting.
Endocannabinoid system
The body’s own signalling network that cannabis interacts with, regulating mood, appetite, sleep and more.
Entourage effect
The theory that cannabinoids and terpenes work together, shaping effects more than THC alone.
Equivalency
The Cannabis Act formula for how product types count toward the 30 g public possession limit.
Feminized seeds
Seeds bred to grow into flower-producing female plants almost every time, what home growers usually want.
Flower
The dried buds of the cannabis plant, the most traditional form for smoking or vaporizing.
Full-spectrum
A product containing the plant’s full range of cannabinoids and terpenes, not just one isolated compound.
Greening out
The unpleasant feeling of having taken too much cannabis, dizziness, nausea, anxiety. It passes.
Hash
Hashish, a traditional concentrate made by collecting and pressing the plant’s resin (trichomes).
Hemp
Cannabis bred to be very low in THC. In Canada, CBD from any source is still regulated as cannabis.
Hybrid
A cross between indica and sativa genetics. Most cannabis sold today is a hybrid.
Indica
A traditional plant-type label associated with relaxing effects, though modern strains are mostly hybrids.
Isolate
A single, purified cannabinoid (e.g. CBD isolate) with everything else removed.
Kief
The loose, powdery trichomes sifted from flower, potent, and the starting point for dry-sift hash.
Legacy market
The unregulated ("grey" or illegal) market, untested product sold outside provincial systems.
Live resin
A concentrate made from flash-frozen fresh cannabis, prized for preserving terpene flavour.
Microdose
A very small dose taken for a subtle effect without feeling impaired.
Moon rocks
Buds dipped in cannabis oil and rolled in kief, extremely potent, and not a beginner’s product.
Munchies
Increased appetite from THC, caused by its effect on the brain’s hunger and reward signals.
Nanoemulsion
A process that shrinks cannabis oil into tiny droplets so drinks and some edibles take effect faster.
Onset
How long a product takes to take effect, minutes for inhaled, up to two hours for edibles.
Phenotype
The observable traits of a specific plant, two seeds of one strain can express differently.
Photoperiod
A cannabis plant that only starts flowering when daily light drops, the traditional, non-autoflowering type.
Pistil
The fine hair-like strands on a bud (often orange when mature), part of the plant’s reproductive anatomy.
Pre-roll
A ready-made cannabis joint sold by licensed retailers.
Rosin
A solventless concentrate pressed from flower or hash using heat and pressure.
RSO
Rick Simpson Oil, a thick, potent full-extract cannabis oil, usually taken orally and dosed in tiny amounts.

A traditional plant-type label associated with energizing effects. Like indica, a loose guide at best.
Shatter

Sinsemilla
Seedless flower from unpollinated female plants, the potent, resin-rich bud sold today.
Solventless
Concentrates made with only heat, pressure, water or sieving, no chemical solvents. Rosin is the classic example.
Standardized cannabis symbol
The red THC warning symbol that must appear on every legal Canadian product containing THC.
Strain
A particular variety of cannabis with its own genetics, cannabinoid, and terpene profile.
Sublingual
Taken under the tongue (e.g. tinctures), where some absorbs directly for a faster, steadier onset.
Terpene
Aromatic compounds that give cannabis its smell (citrus, pine, fuel) and help shape the experience.
THC
Tetrahydrocannabinol, the main intoxicating compound in cannabis, responsible for the "high."
THCA
The raw, non-intoxicating acid form of THC in fresh cannabis. Heat converts it to active THC, see decarboxylation.
Tincture
A liquid cannabis extract, usually taken under the tongue with a dropper for measured dosing.
Titration
Adjusting your dose in small steps to find the lowest amount that works, the safe way to dial in edibles.
Tolerance
Reduced response to cannabis with regular use, meaning more is needed for the same effect.
Topical
A cannabis cream, balm or lotion applied to the skin, typically non-intoxicating.
Trichome
The tiny, frosty, mushroom-shaped glands on cannabis that produce its cannabinoids and terpenes.
Vaporizer
A device that heats cannabis or oil to release vapour without combustion (smoke).
