Meet Professor Terp, our resident plant chemist. Below: the molecules, the receptors, and the reason two "indicas" can feel completely different.
Your body already makes cannabinoid-like molecules. The ECS is a signaling network that helps keep things in balance — appetite, sleep, mood, pain signaling, immune response. Plant cannabinoids work because they fit the same locks.
The short version: THC binds CB1 directly — that's the intoxication. CBD mostly works indirectly and doesn't produce a high.
| Compound | Intoxicating? | What it's known for |
|---|---|---|
| THC (delta-9-tetrahydrocannabinol) | Yes | The primary psychoactive compound; also the basis of approved anti-nausea medicines. |
| THCA | No (raw) | The acid form in the living plant; heat converts it to THC — that's why decarboxylation matters for edibles. |
| CBD | No | Approved as a purified drug for rare epilepsies; widely sold in wellness products. |
| CBG | No | The precursor other cannabinoids are built from; human research is early. |
| CBN | Mildly | Forms as THC ages; heavily marketed for sleep with thin evidence so far. |
| THCV | Dose-dependent | Structurally similar to THC with different effects at different doses; under study. |
Terpenes are aromatic compounds found across the plant kingdom. They give each cultivar its nose — and many researchers think they shape the experience alongside cannabinoids (the debated "entourage effect").
Citrus peel. Also in lemons and oranges.
Pine needles and rosemary. Sharp and fresh.
Mango and hops; earthy-fruity, the most common cannabis terpene.
Lavender. Floral and soft.
Black pepper; unusual in that it binds CB2 receptors directly.
Hops and sage; woody and herbal.
Every regulated package tells a story if you know the fields. Here's a walkthrough of a typical flower label:
Total THC already accounts for THCA conversion — it's the number that matters, not the raw THCA figure. Total CBD works the same way.
Terpenes fade over months. A recent harvest and packaging date usually means a better-smelling, better-tasting product.
Regulated labs test for pesticides, heavy metals, residual solvents, microbials, and mycotoxins. The label or QR code should link to results.
A "10 mg serving" in a 100 mg package means ten doses, not one snack. Portion deliberately.
