Cannabinoids Explained

Short answer: Cannabinoids are chemical compounds that interact with the body’s endocannabinoid system. More than 100 occur in cannabis. A few are intoxicating (delta-9 THC, delta-8 THC, HHC), most are not (CBD, CBG, CBN, CBDV), and their legal status in the US now depends on how they are produced as much as what they are.

What cannabinoids do

Your body has an endocannabinoid system: receptors (mainly CB1 and CB2), the compounds your body makes to activate them (endocannabinoids such as anandamide), and enzymes that break those compounds down. The system is involved in appetite, sleep, mood, pain signaling and memory.

Plant cannabinoids — phytocannabinoids — interact with that system in different ways:

  • Direct agonists bind the receptor and activate it. Delta-9 THC is the classic example.
  • Weak or partial agonists bind less strongly. Delta-8 and HHC behave this way, which is why they are described as milder.
  • Indirect modulators do not bind CB1 much at all but influence the system through other pathways. CBD is the main example.

This is why “CBD and THC are both cannabinoids” tells you almost nothing. They act differently, feel different, and are regulated differently.

Quick comparison

Cannabinoid Intoxicating? Naturally in cannabis? Federal hemp status after 2026
Delta-9 THC Yes, strongly Yes, primary Legal only within total-THC limits
THCA No when raw; yes when heated Yes, the main THC precursor Counted in total THC from Dec 11
Delta-8 THC Yes, milder Trace amounts Commercial (synthesized) product loses status Dec 11
Delta-10 THC Yes, mild Trace amounts Synthesized product loses status Dec 11
HHC Yes Trace only Loses status Nov 12
THCP Yes, reportedly strong Trace amounts Synthesized product loses status Dec 11
THCO Yes No Loses status Nov 12
THCV Mild / disputed Yes, trace Synthesized product loses status Dec 11
CBD No Yes Not scheduled; isolate unaffected
CBG No Yes Not scheduled
CBN No Yes, mostly as THC degrades Not scheduled
CBDV No Yes, trace Not scheduled

“Trace amounts” is the crux of the legal change. A cannabinoid that exists in the plant in tiny quantities cannot be extracted commercially — so the version sold in stores is made in a lab. The 2026 law excludes those products from the definition of hemp.

Intoxicating cannabinoids

Delta-9 THC

The main intoxicating cannabinoid and the one most research has focused on. It binds CB1 strongly. Hemp-derived delta-9 is legal only within strict THC limits. Read the delta-9 guide.

Delta-8 THC

One double bond away from delta-9, weaker at CB1, and usually described as milder and clearer. Commercial delta-8 is synthesized from CBD, which is why it loses federal hemp status on December 11, 2026. Read the delta-8 guide.

HHC

Made by hydrogenating THC. More stable than delta-8 and roughly similar in strength, with a longer duration. Not naturally produced in commercial quantities, so it loses hemp status on November 12, 2026. Read the HHC guide.

THCO

THC with an acetate group attached. No natural source, very little human data, and inconsistent user reports. Loses hemp status on November 12, 2026. Read the THCO guide.

THCP

Reported to be far more potent than delta-9 at the receptor, though human data is minimal and product dosing is often unclear. Treat potency claims with caution. Read the THCP guide.

Delta-10 THC

A minor cannabinoid often described as gentler and more cerebral than delta-8. Very little research. Read the delta-10 guide.

THCV

Studied for appetite and metabolic effects. At low doses it is generally described as non-intoxicating; at high doses, users report a clear-headed stimulation. Read the THCV guide.

Delta-11 THC

A minor isomer with almost no published human research. Any confident claim about its effects is marketing, not science. Read the delta-11 guide.

THCH

A hexyl-chain cannabinoid, one carbon longer than delta-9 and one shorter than THCP. Reported higher CB1 affinity in lab work, but no controlled human studies. Read the THCH guide.

Non-intoxicating cannabinoids

CBD

The most studied non-intoxicating cannabinoid. It does not bind CB1 strongly and does not produce a high. The only cannabis-derived drug approved by the FDA — Epidiolex — is a CBD product, for specific seizure disorders. Read the CBD guide.

CBG

Often called the “mother cannabinoid” because many others derive from it in the plant. Research is early; it is generally described as non-intoxicating. Read the CBG guide.

CBN

Formed as THC degrades. Heavily marketed for sleep, but the human evidence for that claim is thin. It is not a substitute for a sedative and is not intoxicating in the way THC is. Read the CBN guide.

CBDV

A minor cannabinoid structurally related to CBD, under early study for seizure-related research. Not intoxicating. Read the CBDV guide.

The legal layer

Since 2018, the US has regulated cannabinoids by source plant and by delta-9 concentration rather than by molecule. The 2026 changes replace that with a total-THC standard and a per-container cap, and exclude cannabinoids that cannot be naturally produced.

Practical guides

How to evaluate any cannabinoid product

  1. Get the COA. A batch-specific certificate of analysis from an independent lab. It should match the package batch number.
  2. Check total THC, not just the headline cannabinoid. After December 11, 2026, the federal cap is 0.4 mg total THC per container.
  3. Check for residual solvents and reagents. This matters most for synthesized cannabinoids.
  4. Check the date against the law. A product’s legal status can change while it sits on a shelf.
  5. Check your state. State rules can be stricter than federal rules.

Browse products by cannabinoid: delta-8, delta-9, HHC, THCO, THCP, THCV, CBD, CBG and CBDV. THCA does not have its own product category in this catalog; read the THCA guide instead.

Frequently asked questions

What is the difference between CBD and THC?

CBD is not intoxicating and binds CB1 weakly. THC binds CB1 strongly and produces a high. They are different molecules with different effects and different legal treatment.

How many cannabinoids are there?

More than 100 have been identified in cannabis. Only a handful are sold commercially, and only a few have meaningful human research behind them.

Which cannabinoids are intoxicating?

Delta-9 THC, delta-8 THC, delta-10 THC, HHC, THCP and THCO are intoxicating. CBD, CBG, CBN and CBDV are not.

Are cannabinoids legal?

It depends on the cannabinoid, how it was produced, and your state. See the 2026 hemp law guide.

What is the endocannabinoid system?

A network of receptors, signaling molecules and enzymes involved in appetite, sleep, mood, pain and memory. Plant cannabinoids interact with it in different ways.
