THC gets all the attention, but there are over 100 cannabinoids in the cannabis plant. Each one interacts with your body differently.
Walk into our La Mesa location on any given Tuesday, and you'll hear the same questions. "What's the THC percentage?" "Does this have CBD?" "Why does this strain cost more if it's only 18% THC?" These aren't bad questions — they're just incomplete ones.
Here's what 30 years in cannabis has taught us: chasing THC numbers is like judging wine by alcohol content alone. You're missing the whole story.
The Entourage Effect: Why Numbers Don't Tell Everything
The entourage effect is the idea that cannabinoids and terpenes work together rather than in isolation. It is widely discussed, though the research on it is still developing. A 32% THC strain can feel weaker than a 24% strain, and the entourage idea is one explanation people offer for that.
Our Insane OG consistently tests between 28-32% THC, but customers at our Fresno store don't just buy it for the numbers. They come back because of how it feels — and that's where the other cannabinoids come in.
THC: The Heavyweight Champion
Delta-9-tetrahydrocannabinol. The cannabinoid that launched a thousand prohibition laws and just as many late-night convenience store runs.
THC binds directly to CB1 receptors in your brain and CB2 receptors throughout your body. It's responsible for cannabis's psychoactive effects — that elevated feeling that's kept people coming back for centuries.
But here's where it gets interesting. THC percentages don't tell you everything about potency. A 20% THC strain with a myrcene-heavy profile can feel quite different from a 28% THC strain with a limonene-heavy one.
At our Canoga Park location, we've noticed customers are getting smarter about this. They're not just asking for "the strongest stuff" anymore. They're asking about terpene profiles and effects.
THCA vs THC: The Raw Truth
Most lab reports show THCA, not THC. THCA is the non-psychoactive precursor that converts to THC when heated. Raw cannabis won't get you high — it needs decarboxylation through smoking, vaping, or cooking.
The conversion isn't perfect. When labs report 25% THCA, you're looking at roughly 22% THC after decarboxylation. Those numbers matter when you're calculating dosages for edibles or tinctures.
CBD: The Balancing Act
Cannabidiol changed everything. Before CBD hit mainstream awareness around 2014, cannabis was either "medical" or "recreational." CBD blurred those lines permanently.
CBD doesn't bind directly to cannabinoid receptors like THC does. Instead, it works more subtly — influencing how other compounds interact with your endocannabinoid system.
Our budtenders at the Orcutt store report that customers often ask for "high CBD strains" without understanding ratios. A 1:1 THC:CBD strain (like our Harlequin cut that tests around 8% THC and 9% CBD) feels completely different from a 20:1 CBD strain.
The CBD Market Reality
Here's something CBD marketing doesn't always make clear: many hemp-derived CBD products are isolates, containing CBD and little else. Cannabis-derived CBD products are more likely to carry other cannabinoids and terpenes alongside it.
The label usually tells you which kind you are holding: isolate, broad spectrum or full spectrum.
CBG: The Mother Cannabinoid
Cannabigerol doesn't get headlines, but it should. CBG is the precursor to THC, CBD, and CBC. In young cannabis plants, most cannabinoids exist as CBGA (CBG acid). As the plant matures, enzymes convert CBGA into other cannabinoids.
Most strains contain less than 1% CBG because it's been converted to other compounds. But some phenotypes — particularly certain White Widow and Jack Herer lines — maintain higher CBG levels even at harvest.
We carry a few CBG-dominant strains that test between 8-12% CBG with minimal THC.
The Minor League All-Stars
CBC (Cannabichromene)
CBC doesn't bind well to CB1 or CB2 receptors, but it interacts with other receptor systems. It's often found alongside CBD in balanced strains. Our Cannatonic phenotype typically shows 2-4% CBC alongside its 6% CBD and 4% THC profile.
CBN (Cannabinol)
CBN forms when THC degrades over time. Aged cannabis, improperly stored flower, or certain curing techniques increase CBN levels.
That is why CBN is used as a marker of age: flower that has sat longer tends to test higher in it. We cover what the storage research found in does weed go bad?
THCV (Tetrahydrocannabivarin)
THCV is found in higher concentrations in African landrace strains like Durban Poison. It's structurally similar to THC but may produce different effects, especially at lower doses.
Some Durban Poison phenotypes we've carried at our La Mesa store test around 2-3% THCV alongside 18-22% THC. THCV is less studied than THC or CBD, and what it does in people is still an open research question.
Terpenes: The Supporting Cast That Steals the Show
Terpenes aren't cannabinoids, but they work so closely together that separating them doesn't make sense. Every time someone walks into our Canoga Park location and says a strain "smells like lemons" or "tastes like pine," they're talking about terpenes.
Myrcene: The Most Common Terpene
Myrcene is the most common terpene in cannabis, with an earthy, musky aroma also found in mangoes and hops.
Limonene: Citrus Clarity
Limonene gives strains like Sour Diesel their characteristic citrus aroma. It's found in lemon peels, orange rinds, and certain cannabis chemotypes.
Our Insane OG shows significant limonene content — usually 0.6-0.9% — combined with caryophyllene around 0.4-0.7%. That combination creates the strain's distinctive profile that keeps customers coming back.
Caryophyllene: The Spicy Exception
Caryophyllene is unique among terpenes because it also acts as a cannabinoid, binding to CB2 receptors. It's found in black pepper, cloves, and many OG Kush lineage strains.
Strains with high caryophyllene content (above 0.5%) often have that spicy, peppery finish that experienced smokers recognize immediately.
Reading Lab Reports: What Actually Matters
A Certificate of Analysis (COA) is the lab report behind a product's label. Here's what to look for:
Total Active Cannabinoids: This includes THC, CBD, CBG, CBC, CBN, and others. A strain with 25% THC and 2% other cannabinoids hits differently than one with 25% THC and no supporting cast.
Terpene Profile: Look for strains with total terpene content above 1%. The individual terpenes matter more than the total, but strong terpene profiles generally indicate quality cultivation and processing.
Harvest Date: Cannabinoids and terpenes degrade over time. Flower harvested 3-4 months ago will have different profiles than the same genetics harvested 10 months ago.
The Future: What's Coming Next
Research into minor cannabinoids is accelerating. THCP, discovered in 2019, appears to bind to CB1 receptors more effectively than THC. Delta-8 THC offers a different experience than traditional delta-9 THC.
But here's the thing — cannabis worked for thousands of years before we knew what cannabinoids were. The plant developed these compounds through evolution, not market research.
Beyond the Buzz: Practical Applications
Understanding cannabinoids helps you compare products on more than one number. The THC percentage, the THC:CBD ratio and the terpene profile are all on the COA, and together they tell you far more than any single figure.
Our customers at the Orcutt location have caught on to this. They're asking for specific terpene profiles and cannabinoid ratios, not just "your strongest indica."
The Dr. Greenthumb's Difference
After 30 years, we've learned that great cannabis isn't about one number — it's about the symphony. Our Insane OG works because THC, terpenes, and minor cannabinoids create something greater than the sum of their parts.
When B-Real started growing in 1988, he wasn't chasing THC percentages. He was chasing the perfect high.
The cannabis plant produced over 100 cannabinoids for a reason. We're just beginning to understand why.
