- CBG acts as the stem-cell mother cannabinoid that synthesizes into THC, CBD, and CBC.
- CBN is a natural degradation product of THC that contributes to nighttime relaxation.
- THCV and CBDV represent the cutting edge of modern functional and non-sedating breeding.
What Are Cannabinoids?
Cannabinoids are chemical compounds produced by cannabis that interact with the body's endocannabinoid system — a network of receptors that helps regulate mood, appetite, pain sensation, and immune response. While THC and CBD are the most famous, the cannabis plant produces over 100 different cannabinoids. Each has unique effects and potential benefits.
THC — The Psychoactive Powerhouse
Tetrahydrocannabinol (THC) is the primary psychoactive compound in cannabis. It binds directly to CB1 receptors in the brain, producing the characteristic "high" — euphoria, altered perception, relaxation, and increased appetite. THC content in modern strains ranges from 15% to 32%+.
Medical uses: Pain relief, nausea suppression, appetite stimulation, insomnia, muscle spasticity. Strains highest in THC include Permanent Marker, Godfather OG, and Gorilla Glue #4.
Key fact: THC is technically a prodrug — the liver converts it to 11-hydroxy-THC, which is actually more psychoactive. This is why edibles feel different (and stronger) than smoking.
CBD — The Non-Psychoactive Balancer
Cannabidiol (CBD) is non-psychoactive and actually counteracts some of THC's effects. It binds to different receptors and modulates the endocannabinoid system without producing a high. CBD has exploded in popularity for its therapeutic potential.
Medical uses: Anxiety reduction, anti-inflammatory, seizure disorders, chronic pain, neuroprotection. Notable CBD strains include ACDC (high CBD, low THC) and Harlequin.

Key fact: CBD can reduce the psychoactive effects of THC. Strains with a balanced 1:1 THC:CBD ratio (like some phenotypes of Harlequin and Cannatonic) provide a clearer, more functional experience than high-THC strains.
CBG — The Stem Cell Cannabinoid
Cannabigerol (CBG) is called the "mother" or "stem cell" cannabinoid because all other cannabinoids start as CBG. As the cannabis plant matures, CBG is converted by specific enzymes into THC, CBD, and CBC. Plants harvested earlier contain more CBG.
Medical uses: Anti-inflammatory, antibacterial, neuroprotective, appetite stimulation. CBG is being researched for glaucoma and inflammatory bowel disease.
Key fact: CBG is typically found in very low concentrations (under 1%) in most mature cannabis. High-CBG strains are rare but being actively developed by breeders for their unique therapeutic profile.
CBN — The Sleep Cannabinoid
Cannabinol (CBN) is formed when THC is exposed to oxygen over time — it's the degradation product of THC. Aged cannabis that has been stored for long periods naturally develops higher CBN levels. CBN is mildly psychoactive (about 10% as potent as THC) and is best known for its sedative effects.
Medical uses: Sleep aid, mild pain relief, appetite stimulation. Often found in aged cannabis or specifically bred for nighttime use.
Key fact: The "sleepy weed" effect often attributed to indicas may actually be linked to higher CBN levels from aged cannabis rather than the strain's genetics directly. Fresh indica and sativa both have minimal CBN — it develops over time.
THCV, CBC, and Beyond
THCV (Tetrahydrocannabivarin) is a minor cannabinoid gaining attention for its appetite-suppressing and energy-boosting effects. Structurally similar to THC but produces a very different experience. Found in higher concentrations in certain African and Asian landraces like Durban Poison.
CBC (Cannabichromene) interacts with pain and inflammation pathways without psychoactive effects. Often found alongside CBD in hemp-type cannabis.
CBDV (Cannabidivarin) is structurally similar to CBD and is being researched for epilepsy and autism spectrum disorders.
Choosing by Cannabinoid Profile
When selecting a strain, consider the full cannabinoid profile, not just THC percentage. A strain with 20% THC and 2% CBD may feel very different from one with 20% THC and no CBD. Tools like this archive's strain profiles include THC and CBD data where available — use them to make informed choices. The future of cannabis selection is chemotype-driven, not just strain-name-driven.
Featured Strains in This Guide
Explore the verified genetics, lineage, and terpene profiles of strains analyzed in this article:
ACDC
ACDC, AC/DCThe most famous high-CBD strain in modern cannabis. A Cannatonic phenotype with an extraordinary 20:1 CBD-to-THC ratio, ACDC revolutionized medical cannabis by delivering therapeutic effects without psychoactive intoxication.
Permanent Marker
PM, The Marker(Biscotti × Jealousy) × Jealousy F2. Bred by JBeezy (Seed Junky Genetics) and hunted by Doja Pak, Permanent Marker was crowned Leafly's 2023 Strain of the Year for its unmistakable uncapped Sharpie ink aroma, 26–32% THC, and devastating modern hybrid euphoria.
Godfather OG
Godfather OG, GodfatherAn Alpha OG x XXX OG cross that became the face of the high-THC potency race. Regularly testing above 30% THC, Godfather OG holds the reputation as one of the strongest strains ever created.
Gorilla Glue #4
GG4, Original Glue(Chem's Sister × Sour Dubb) × Chocolate Diesel. The legendary accidental powerhouse created by Joesy Whales and Lone Watty, famous for glue-like resin output, a historic 2014 Cannabis Cup double sweep, and a landmark trademark battle.
