What Are THC and CBD Compounds?

Cannabis sativa produces more than 140 known cannabinoids, and nearly all of them fall into two structural families: the THC type and the CBD type. THC-type compounds share the core structure of delta-9 tetrahydrocannabinol, while CBD-type compounds share the structure of cannabidiol. The plant builds most of them first as acidic parent molecules such as THCA and CBDA, which shift into their neutral forms through heat or time.

The complete list breaks into three groups:

cannabis cannabinoids list and effects

  • THC compounds: delta-9 THC, THCA, delta-8 THC, delta-10 THC, THCV, THCP, THCB, THCH, and THC-O acetate.
  • CBD compounds: CBD, CBDA, CBDV, CBDVA, and CBDP.
  • Shared minor cannabinoids: CBG, CBC, CBN, CBL, and CBT, which are precursors or breakdown products rather than THC or CBD themselves.

Complete List of THC Compounds

Delta-9 THC (Tetrahydrocannabinol)

Delta-9 THC is the primary intoxicating cannabinoid in cannabis and binds strongly to CB1 receptors in the brain. It is what most people mean when they say THC, and it drives the euphoric, appetite-stimulating, and pain-relieving effects linked to the plant.

THCA (Tetrahydrocannabinolic Acid)

THCA is the raw, non-intoxicating form found in fresh, unheated flower. Heating it above roughly 220 degrees Fahrenheit removes a carboxyl group and converts it into delta-9 THC, a process called decarboxylation. That is why raw cannabis does not produce a high, while smoked or vaped cannabis does.

Delta-8 THC

Delta-8 THC is a minor cannabinoid with a double bond in a different position than delta-9. It produces milder psychoactive effects and is often manufactured from hemp-derived CBD through isomerization. It appears naturally in cannabis, but usually at very low levels.

Delta-10 THC

Delta-10 THC is another minor isomer, reported to feel more energizing and less sedating than delta-9. It occurs in trace amounts in the plant and is most often produced through chemical conversion of CBD.

THCV (Tetrahydrocannabivarin)

THCV is a propyl-side-chain analog of THC found in higher concentrations in some African landrace strains. At low doses it may act as a CB1 antagonist, and at higher doses it can produce a short, sharp psychoactive effect.

THCP (Tetrahydrocannabiphorol)

THCP has a seven-carbon side chain instead of the five-carbon chain in delta-9 THC. Early research suggests it binds CB1 receptors with notably higher affinity, though it appears in cannabis at extremely low levels.

THCB, THCH, and Other THC Variants

THCB (tetrahydrocannabutol) and THCH (tetrahydrocannabihexol) are homologs with butyl and hexyl side chains. Both are minor constituents identified through modern phytocannabinoid profiling.

THC-O Acetate

THC-O acetate is a semi-synthetic acetylated form of THC, not a compound the plant produces on its own. It is reported to have a slower onset and stronger perceived potency than delta-9 THC.

Complete List of CBD Compounds

CBD (Cannabidiol)

CBD is the second most abundant cannabinoid in cannabis and does not produce intoxication. It interacts weakly with CB1 and CB2 receptors and is studied for anxiety, seizure disorders, and inflammation.

CBDA (Cannabidiolic Acid)

CBDA is the acidic precursor to CBD in raw cannabis. It converts to CBD when heated, and on its own it is studied for nausea and inflammatory pathways.

CBDV and CBDVA

CBDV (cannabidivarin) is a propyl analog of CBD, and CBDVA is its acidic precursor. CBDV appears at higher levels in some indica-leaning and landrace cultivars and is researched for repetitive behaviors and nausea.

CBDP (Cannabidiphorol)

CBDP is the CBD analog with a seven-carbon side chain, matching the chain length of THCP. It is a rare minor cannabinoid and remains lightly studied.

Other Minor Cannabinoids in the Plant

CBG and CBGA

CBGA is the original precursor from which THCA, CBDA, and CBCA are built by plant enzymes. CBG is its neutral form and is often called the mother cannabinoid.

CBC and CBCA

CBC (cannabichromene) is a non-intoxicating cannabinoid that may interact with TRP channels rather than CB1 receptors. CBCA is its acidic parent.

CBN (Cannabinol)

CBN forms as THC oxidizes over time, which is why aged flower tends to show higher CBN. It binds CB1 receptors weakly and is associated with sedative-leaning effects.

CBL and CBT

CBL (cannabicyclol) and CBT (cannabicitran) are rare cannabinoids formed through degradation and cyclization. Both appear in very small quantities and are still being mapped.

How Do Cannabinoids Differ From Terpenes and Flavonoids?

Terpenes are aromatic oils that give each strain its smell, and flavonoids are the pigments that contribute color and taste. Neither class is a cannabinoid, and neither binds CB1 or CB2 receptors directly. They belong to the plant's chemistry, but they are not part of the THC and CBD compound list.

Frequently Asked Questions

How many THC and CBD compounds exist?

Researchers have identified more than 140 cannabinoids in cannabis, with roughly a dozen THC-type and CBD-type compounds found in measurable amounts. The rest are minor or trace constituents.

Is THCA psychoactive?

No. THCA does not produce intoxication until it decarboxylates into delta-9 THC, which happens with heat.

What is the main difference between THC and CBD?

THC binds CB1 receptors strongly and produces intoxication, while CBD binds them weakly and does not. That single receptor difference shapes most of their effects.

Are all THC compounds legal in the US?

No. Delta-9 THC above 0.3 percent dry weight is federally controlled, while hemp-derived delta-8, delta-10, and THC-O sit in a shifting state-by-state patchwork. Always check your state's rules before buying.
