Cannabis Glossary: 60 Terms Every Consumer Should Know in 2026
The cannabis world has its own language — and in 2026, with THCa, liquid diamonds, decarboxylation, and endocannabinoid systems becoming everyday conversation, understanding the terminology is essential. This glossary covers 60 essential cannabis terms every informed consumer should know.

A–C
Badder/Budder: A soft, malleable cannabis concentrate with a creamy, butter-like consistency. Made by agitating (whipping) BHO extract during the purge process.
BHO (Butane Hash Oil): Cannabis extract produced using butane as the solvent. The base for many concentrate types including shatter, wax, and live resin.
Cannabidiol (CBD): The second most abundant cannabinoid in cannabis. Non-psychoactive with extensive research into wellness applications. Legal federally when hemp-derived.
Cannabinoid: Any chemical compound that interacts with the endocannabinoid system. Includes THC, THCa, CBD, CBG, CBN, and over 100 others found in cannabis.
Cannabis Sativa: One of the primary cannabis species. Associated with more energizing, cerebral effects — though modern science recognizes that indica/sativa distinctions are more terpene-driven than genetics-driven.
Caryophyllene: A terpene found in black pepper and many cannabis strains. The only terpene known to directly activate CB2 receptors. Associated with anti-inflammatory effects.
CB1 Receptor: Cannabinoid receptors concentrated in the brain and central nervous system. Primary target of THC producing psychoactive effects.
CB2 Receptor: Cannabinoid receptors concentrated in the immune system and peripheral tissues. Associated with anti-inflammatory effects.
CBG (Cannabigerol): The “mother cannabinoid” — THCa and CBD are biosynthesized from CBGa. Non-psychoactive with research interest in focus and anti-inflammatory applications.
CBN (Cannabinol): A cannabinoid produced when THC degrades with heat and age. Mildly sedating. Popular in sleep-focused cannabis products.
Certificate of Analysis (COA): Lab report from an accredited third-party laboratory confirming cannabinoid content, terpene profile, and safety testing (pesticides, heavy metals, microbials). Essential for any cannabis purchase. All Ghost Farms products include full COA documentation.
Crumble: A dry, honeycomb-textured cannabis concentrate. Produced through a longer, lower-temperature purge than wax.
Curing: The post-harvest process of slowly reducing cannabis moisture in sealed containers over weeks to develop flavor, reduce harshness, and stabilize the product.
D–F
Dabbing: Consuming cannabis concentrates by vaporizing them on a heated surface (called a nail or banger) using a dab rig.
Decarboxylation: The chemical process of applying heat to convert THCa into psychoactive THC (or CBDa into CBD). Occurs automatically when smoking or vaping cannabis.
Delta-8 THC: A cannabinoid with milder psychoactive effects than Delta-9 THC. Commercially produced through chemical conversion of CBD. Exists in a legal gray area.
Delta-9 THC: The primary psychoactive cannabinoid in cannabis. Federally Schedule I; legal in states with recreational or medical cannabis programs.
Diamonds: Pure THCa crystalline that forms during certain extraction processes. Can reach 99%+ purity. Base of liquid diamond vapes.
Disposable Vape: An all-in-one vape device pre-filled with cannabis extract that is discarded when empty. Modern versions include rechargeable batteries. Ghost Farms’ 7g disposable is the market leader.
Distillate: A highly refined cannabis extract that isolates specific cannabinoids by removing all other plant compounds including terpenes. Most common vape cartridge oil.
Endocannabinoid System (ECS): A complex biological system in humans and most animals that regulates numerous physiological functions. Consists of endocannabinoids, receptors (CB1 and CB2), and enzymes.
Entourage Effect: The theory that cannabinoids and terpenes work synergistically to produce effects greater than any single compound alone. Supports use of full-spectrum over isolated products.
Flower: The harvested, dried bud of the cannabis plant. The most traditional consumption format.
Full Spectrum: Cannabis extract that preserves all naturally occurring cannabinoids and terpenes from the source plant, supporting the entourage effect.
G–L
Gram: Standard unit of cannabis measurement. Typical prices range from $8–20/gram for flower depending on quality tier.
Hash: Compressed cannabis resin. Traditional concentrate produced by separating trichomes from cannabis plant material.
Hemp: Cannabis plants containing less than 0.3% Delta-9 THC by dry weight under the 2018 Farm Bill. Legal federally; basis for CBD, THCa, and hemp-derived products.
HHC (Hexahydrocannabinol): A hydrogenated form of THC with unique psychoactive properties. Legal in more markets than Delta-9 due to its different chemical structure.
Indoor: Cannabis cultivation in fully controlled indoor environments. Associated with highest quality, most consistent buds, and strongest terpene development.
Indica: Cannabis strain classification traditionally associated with sedating, relaxing body effects. Modern science attributes these effects more to terpene profiles than pure genetics.
Infused Pre-Roll: A pre-roll joint enhanced with cannabis concentrate (kief, live resin, or oil) for significantly elevated potency.
Kief: The fine, powdery trichome crystals that separate from cannabis flower. Can be collected in the bottom chamber of a 4-piece grinder.
Limonene: A citrus-scented terpene associated with mood elevation and stress relief. Abundant in Runtz, Gelato, and Wedding Cake strains.
Linalool: A floral, lavender-scented terpene with strong calming and anti-anxiety properties. Abundant in Zkittlez and Purple strains.
Live Resin: Cannabis extract made from flash-frozen fresh plants, preserving maximum terpene content. Superior flavor versus traditional extracts. Used in Ghost Farms’ premium vapes.
Live Rosin: Solventless extract made from fresh-frozen cannabis using only heat and pressure. The “cleanest” extraction method.
Liquid Diamonds: THCa crystalline dissolved in terpene sauce. Maximum potency plus full terpene flavor. The premier extract for premium vapes.
M–R
Microdosing: Consuming sub-psychoactive doses of cannabis to access subtle benefits (focus, mood, pain relief) without impairment.
Myrcene: The most abundant terpene in most cannabis strains. Earthy, tropical aroma. High myrcene associated with sedating “couch-lock” effects.
Nug: Individual cannabis flower bud. “Top-shelf nugs” refers to premium whole buds (versus shake or trim).
Ounce (oz): 28 grams. Standard bulk cannabis purchase unit.
Phenotype: The physical expression of a cannabis plant’s genetics. Different phenotypes (phenos) of the same strain can express different aromas, effects, and appearance.
Pinene: Pine-scented terpene associated with mental alertness and focus. Found in Jack Herer and Blue Dream.
Pre-Roll: A commercially produced joint — cannabis flower rolled in paper with a filter tip by a manufacturer. Ghost Farms pre-rolls use premium flower, not shake.
Rosin: Solventless extract produced using heat and pressure only. Clean, full-spectrum, increasingly popular for its purity.
S–Z
Sativa: Cannabis classification traditionally associated with energizing, cerebral effects. Best for daytime use, focus, and creativity.
Shake: Small pieces and fragments that fall off cannabis buds during handling and storage. Lower quality than whole buds — used in many budget pre-rolls.
Shatter: A brittle, glass-like cannabis concentrate. One of the most potent and stable concentrate forms.
Terpene: Aromatic compounds in cannabis (and all plants) responsible for distinctive smells and flavors. Also influence the cannabis effect profile.
Terpinolene: A floral-herbal-pine terpene associated with energizing effects. Dominant in Durban Poison and Jack Herer.
THCa (Tetrahydrocannabinolic Acid): Raw, non-psychoactive form of THC in the living cannabis plant. Converts to psychoactive THC when heated. Federally compliant when hemp-derived. Available from Ghost Farms with nationwide delivery.
THCp: A naturally occurring cannabinoid claimed to bind CB1 receptors with dramatically higher affinity than THC. Very potent in small amounts.
Trichome: Tiny hair-like structures on cannabis buds that produce and contain cannabinoids and terpenes. The “frosty” appearance of premium buds is trichome coverage.
Vape Cartridge (Cart): A pre-filled cannabis oil cartridge that attaches to a 510-thread battery. Refillable battery + replaceable cart format.
Wax: Soft, malleable cannabis concentrate with an opaque, waxy consistency. Made by agitating BHO during the purge process.
