Terpenes 101: The Aromatic Compounds Behind How Weed Smells and Feels
If you've ever picked a strain by smell alone, you were already reading terpenes without knowing it. Let's make that instinct a lot more precise.
Terpenes are aromatic compounds produced in the same trichomes that produce THC and CBD. They're not unique to cannabis: limonene is in citrus peels, pinene is in pine needles, and linalool is in lavender. But cannabis produces an unusually wide range of them, and the specific combination is what gives each strain its distinct smell and flavor.
The entourage effect
Terpenes are widely believed to modulate the effects of THC and CBD rather than just contributing smell, working alongside cannabinoids rather than independently. This is often called the "entourage effect." The research here is still developing, but the practical upshot for shoppers is consistent: two strains with similar THC% can feel noticeably different depending on their terpene profile, which is why potency alone is a poor way to choose a strain.
The major terpenes
- Myrcene: earthy, musky, sometimes described as clove-like. Associated with sedation and relaxation; the most common terpene in cannabis overall.
- Limonene: bright and citrusy. Associated with elevated mood and stress relief.
- Caryophyllene: peppery and spicy. The only terpene also known to bind directly to cannabinoid receptors (specifically CB2), which is part of why it's studied for anti-inflammatory effects.
- Pinene: sharp, pine-like. Associated with alertness, and may counteract some of the short-term memory effects of THC.
- Linalool: floral, lavender-like. Associated with calm, and one of the more sedating terpenes outside of myrcene.
Every strain page on Canopy color-codes its terpene profile using this same palette, so once you know what a terpene tends to do, you can scan a strain page and get a real read on how it'll likely feel, not just how strong it is.
