Quick picks if you are deciding right now
Most people walk in asking about potency. Terpenes rarely come up until the first inhale, and that is backwards. Here is how I sort it for someone who wants a fast answer.
cannabinoids list for medical use
1. THC flower with a printed terpene panel (best all-rounder)
If I had to point one direction, it is this. You get the cannabinoid profile you came for and you can read the terpene numbers before you pay. Ask to see the COA. A label that lists myrcene, limonene, and caryophyllene percentages is doing more for you than a big THC number alone.

2. Live resin or live rosin (best for flavor chasers)
Flash-frozen plant material keeps volatile terpenes that drying and curing can burn off. If taste is the point, this is the category. The cannabinoid content is still front and center, usually high, but the aroma is the reason to buy.

3. CBD or CBG dominant product (best if you want no high)
Here the cannabinoid matters far more than the terpenes. CBD does not bind CB1 the way THC does, so the intoxicating effect is not there. Terpenes add a nice smell and little else at typical retail concentrations.
4. Full-spectrum tincture (best for steady, repeatable dosing)
Oils hold both cannabinoids and terpenes, and you can measure a dose with a dropper. Good for people who want consistency instead of a spike.
Cannabinoids vs terpenes: the short answer
Cannabinoids are the compounds that bind your body's receptors and shape how you feel. THC, CBD, CBG, CBN, and THCA are the names you see most. Terpenes are the aromatic oils that decide how the flower smells and tastes. They exist in citrus, pine, hops, lavender, and black pepper too, which is why a cannabis strain can remind you of all four. Terpenes are not intoxicating on their own. Cannabinoids are. That single line settles most of the confusion.
What cannabinoids actually do
THC binds CB1 receptors in the brain and produces the high. CBD does not bind CB1 directly. It acts as a negative allosteric modulator, which is a technical way of saying it can soften or shift how THC behaves at the receptor. CBG and CBN show up in smaller amounts and get studied for their own activity. THCA is the acidic form found in raw plant material, and it does not get you high until heat converts it to THC. That conversion is why decarboxylation matters in edibles.
Potency labels report these as percentages of weight. Twenty percent THC flower means roughly 200 mg of THC per gram, though combustion destroys some of it.
What terpenes actually do
Terpenes are volatile. They evaporate at relatively low temperatures, which is why a jar left open in a warm car smells like nothing a week later. Myrcene, limonene, pinene, linalool, terpinolene, and beta-caryophyllene are the ones printed on most panels. Each has a distinct scent and its own boiling point, which is the whole logic behind low-temperature dabbing and vaporizing.
Do they change the experience beyond smell? That is the entourage effect, and it is still a hypothesis rather than a settled fact. Some research suggests terpenes can modulate cannabinoid activity or ease certain side effects. I treat that as promising, not proven, and I tell customers the same thing. What is certain: they control aroma, flavor, and how harsh the smoke feels.
Side by side
- Function: cannabinoids bind receptors, terpenes carry scent and flavor.
- Intoxication: THC does, terpenes do not.
- Concentration: cannabinoids run 10 to 30 percent in flower, terpenes usually sit under 3 percent.
- Stability: cannabinoids hold up in storage, terpenes degrade with heat, light, and air.
- Testing: both appear on a COA, on separate panels.
How to shop it
- Decide the cannabinoid first. THC for effect, CBD or CBG for no high, a mix if you want a gentler ride.
- Then pick the terpene direction. Limonene and pinene for a bright, alert feel. Myrcene and linalool for something heavier and quieter.
- Check the harvest date. Old flower loses terpenes long before it loses THC.
- Store it in glass, in the dark, sealed. That protects the terpenes you paid for.
Bottom line
Cannabinoids decide what happens. Terpenes decide what it tastes and smells like, and they may nudge the rest. Buy for the cannabinoid profile you need, then use terpenes to fine-tune the experience. A COA that shows both is worth more than a marketing name every time.
