CANNABIS EXPLAINER

Cannabinoids Explained: THC, CBD, CBN, CBG & More

Cannabinoids are the active chemical compounds found in the cannabis plant. More than 100 distinct cannabinoids have been identified. THC and CBD are the most studied, but minor cannabinoids like CBN, CBG, and CBC are gaining scientific attention for their unique properties.

How Cannabinoids Work

Cannabinoids interact primarily with the human endocannabinoid system (ECS), a complex network of receptors, enzymes, and endogenous ligands that regulates mood, pain, appetite, sleep, and immune function. The two main receptor types are CB1 (concentrated in the brain and CNS) and CB2 (found in immune tissue and peripheral organs).

THC binds directly to CB1 receptors, producing the psychoactive effects cannabis is known for. CBD does not directly bind to CB1 or CB2 but modulates many other receptor systems, producing effects without significant intoxication.

The Major Cannabinoids

CannabinoidPsychoactive?Primary Effects
THCYesEuphoria, relaxation, pain relief, appetite stimulation
CBDNoanxiety relief, anti-inflammatory, neuroprotective
CBNMildlySedation, sleep aid, antibacterial
CBGNoNeuroprotection, anti-inflammatory, may reduce IOP
CBCNoAnti-inflammatory, antidepressant, pain relief
THCVLow doses: NoAppetite suppression, clear-headed, fast-acting

The Entourage Effect

The "entourage effect" describes how cannabinoids work synergistically with each other and with terpenes to produce effects greater than any single compound alone. Full-spectrum cannabis products retain all cannabinoids and terpenes and are believed to produce more nuanced therapeutic effects compared to isolated CBD or THC products.

This is why many medical patients prefer whole-plant cannabis over isolated cannabinoid supplements, and why strain selection matters — different cannabinoid and terpene profiles create distinctly different experiences.

THC vs. CBD: The Key Difference

THC (tetrahydrocannabinol) is the primary intoxicating cannabinoid. It produces euphoria, alters perception, stimulates appetite, and provides strong pain relief — but also causes anxiety in some users and creates impairment. CBD (cannabidiol) is non-intoxicating, has strong anti-anxiety and anti-inflammatory properties, and counteracts some of THC's more intense effects when taken together.
