The major cannabinoids are THC, CBD, and CBG, followed by smaller players such as CBC, CBN, THCV, and CBDV. THC is the only common cannabinoid that produces a strong high, CBD does not intoxicate, and CBG acts as the parent compound the plant builds first. Each one interacts with the body's endocannabinoid receptors in a slightly different way, which is why two strains with similar THC levels can feel very different.

What Are Cannabinoids?
Cannabinoids are chemical compounds made in the resin glands, called trichomes, on the flowers of Cannabis sativa. Scientists have identified more than 100 of them, but only a handful appear in amounts large enough to matter. THC, CBD, and CBG make up the bulk of what you see on a lab report.
Cannabinoids vs Terpenes: What's the Difference?
Cannabinoids interact with the endocannabinoid system, a network of receptors and enzymes that helps regulate mood, appetite, sleep, and pain signaling. CB1 receptors sit mostly in the brain and central nervous system, while CB2 receptors cluster in immune tissue. How tightly a cannabinoid binds those receptors shapes its effect.

THC: The Main Psychoactive Cannabinoid
Delta-9 tetrahydrocannabinol (THC) binds CB1 receptors directly, producing euphoria, relaxation, altered perception, and increased appetite. It also relieves nausea, which is why pharmaceutical THC is prescribed for chemotherapy patients. Effects begin within minutes when inhaled and within 30 to 90 minutes when eaten.
What is THCA?
THCA is the raw, acidic form of THC found in fresh plant material. It does not get you high until heat or time removes the acid group, a process called decarboxylation. Smoking, vaping, and baking all convert THCA into THC.
CBD: The Non-Intoxicating Cannabinoid
Cannabidiol (CBD) does not produce a high because it binds CB1 receptors weakly. It acts instead as a modulator, easing anxiety, inflammation, and seizure activity without impairing motor control. The FDA has approved a CBD-based prescription drug for severe childhood epilepsy, the strongest clinical evidence for any cannabinoid besides THC.
CBG: The Precursor Cannabinoid
Cannabigerol (CBG) starts as CBGA, the first cannabinoid the plant builds, and enzymes then convert it into THCA, CBDA, and CBCA. That makes CBG the mother molecule of cannabis, and it usually survives in trace amounts. Early research points to antibacterial, anti-inflammatory, and appetite-related activity.
Other Major and Minor Cannabinoids
- CBC (cannabichromene): non-intoxicating and studied for pain and inflammation, often paired with CBD.
- CBN (cannabinol): a THC breakdown product linked to sedation and often marketed for sleep.
- THCV (tetrahydrocannabivarin): intoxicating at high doses, studied for appetite suppression and blood sugar.
- CBDV (cannabidivarin): non-intoxicating and researched for nausea and repetitive behaviors.
- CBDA and CBGA: raw acid forms with no high, the starting point for decarboxylation.
Do Cannabinoids Work Better Together?
Whole-plant extracts contain dozens of cannabinoids plus terpenes and flavonoids, and some researchers argue these compounds amplify one another, an idea called the entourage effect. Evidence for the concept is still mixed and mostly preclinical. What is clear is that THC and CBD influence each other, since CBD can soften some THC side effects.
How to Read Cannabinoid Levels on a Label
Lab reports list total THC and total CBD, which combine the acid and activated forms. Look for third-party testing from an accredited lab, plus a batch date, so you know what you are buying. Potency varies widely between products, and a 30% THC flower can hit harder than a 10% one.
Frequently Asked Questions
Which cannabinoid gets you high?
Delta-9 THC is the main intoxicating compound, with THCV producing milder effects at high doses. CBD, CBG, CBC, CBN, and CBDV do not get you high.
Is CBG stronger than CBD?
CBG is not stronger, just different. It binds receptors in its own way and appears in much smaller amounts, which makes it costlier to extract.
Are cannabinoids legal in the US?
Legality depends on the source. Hemp-derived products with 0.3% or less delta-9 THC are federally legal, while cannabis-derived THC remains regulated state by state.
