Cannabis Terpenes Guide: What They Are and Why They Matter
If you've ever noticed that some cannabis strains smell like citrus while others smell like pine or diesel, you've experienced terpenes. These aromatic compounds do far more than create pleasant scents—they influence how cannabis makes you feel and may explain why different strains produce different effects.
Understanding terpenes is the key to moving beyond basic THC percentages and finding cannabis that truly works for you.
Quick Answer
Terpenes are aromatic compounds found in cannabis and many other plants that create distinctive smells and flavors. More importantly, they interact with cannabinoids to influence your high—a phenomenon called the "entourage effect." Common terpenes include myrcene (earthy, sedating), limonene (citrus, uplifting), pinene (pine, alerting), and linalool (floral, calming). Knowing your preferred terpenes helps you choose strains that match your desired effects.

What Are Terpenes?
Terpenes are organic compounds produced by plants, including cannabis. They're responsible for the characteristic aromas of many plants—the scent of lavender, the zing of citrus, the freshness of pine.
Not Just Cannabis
Terpenes exist throughout nature:
- Limonene: Lemons, oranges
- Pinene: Pine needles, rosemary
- Linalool: Lavender
- Myrcene: Mangoes, hops
- Caryophyllene: Black pepper, cloves
When you smell these plants, you're experiencing the same terpenes found in cannabis.
Why Plants Produce Terpenes
In nature, terpenes serve plants by:
- Attracting pollinators
- Repelling pests
- Protecting against environmental stress
- Fighting bacteria and fungi
Terpenes in Cannabis
Cannabis produces over 200 different terpenes, though most strains contain only a handful in significant amounts. The specific combination creates each strain's unique aroma profile—and potentially its distinctive effects.
The Entourage Effect
The "entourage effect" describes how cannabis compounds work together synergistically, with terpenes enhancing or modifying cannabinoid effects.
How It Works
Rather than acting independently:
- Terpenes may enhance THC absorption
- Some terpenes interact with the same receptors as cannabinoids
- Combinations create effects different from isolated compounds
Research Evidence
Studies suggest:
- Myrcene may increase THC's sedating effects
- Limonene may boost mood and reduce anxiety
- Pinene may counteract THC-induced memory impairment
- Linalool may enhance calming properties
Why Full-Spectrum Matters
This is why many users prefer full-spectrum cannabis products over isolates. The complete terpene profile works with cannabinoids to create the full experience.

Terpenes vs THC: What Matters More?
The THC Myth
Many consumers focus exclusively on THC percentage, but research and anecdotal evidence suggest terpene profiles may be equally important for predicting effects.
Why Terpenes Deserve Attention
- Two 25% THC strains can feel completely different based on terpene content
- Terpenes influence whether you feel energized or sedated
- Your individual response to specific terpenes is personal
- Flavor and aroma come entirely from terpenes
Finding Your Profile
Instead of chasing THC numbers:
1. Note strains you've enjoyed
2. Research their terpene profiles
3. Look for common terpenes across favorites
4. Seek new strains with similar profiles
How to Use Terpene Information
At the Dispensary
Ask about terpenes:
- Request lab testing results showing terpene content
- Ask budtenders about dominant terpenes in strains
- Use the smell test—your nose knows what appeals to you
Match terpenes to goals:
- Energy/focus: Limonene, pinene, terpinolene
- Relaxation/sleep: Myrcene, linalool
- Mood lift: Limonene, caryophyllene
- Pain/inflammation: Caryophyllene, myrcene, linalool
Reading Lab Results
Terpene testing shows percentage by weight:
- 0.1-0.5%: Low presence
- 0.5-1%: Moderate presence
- 1%+: High presence (dominant terpene)
Look for strains where your preferred terpene is in the top 3.
The Nose Test
Don't underestimate your instincts. If a strain smells appealing to you, your body may be drawn to those terpenes. If it smells off-putting, trust that reaction.
Preserving Terpenes
Terpenes are volatile—they evaporate easily. Here's how to keep them:
Storage
- Temperature: Store cool (60-70°F), away from heat
- Light: Keep in dark or opaque containers
- Air: Use airtight containers
- Humidity: Maintain 58-62% RH
Consumption Method
Different methods preserve terpenes differently:
Optimal Vaping Temperatures
Each terpene has a different boiling point:
- Pinene: 311°F (155°C)
- Myrcene: 332°F (167°C)
- Limonene: 348°F (176°C)
- Linalool: 388°F (198°C)
- Caryophyllene: 266°F (130°C)
Lower temperature vaping preserves more terpenes while still activating THC.
Pro Tips
1. Keep a strain journal noting effects and look up terpenes afterward
2. Smell before you buy when possible—trust your nose
3. Lower vape temperatures preserve more terpene flavor and effects
4. Fresh is better—old cannabis loses terpenes first
5. Look at total terpene percentage, not just individual terpenes
6. Terpene entourage matters—how they combine affects experience
7. Don't dismiss low-THC strains if they have compelling terpene profiles
8. Similar names don't mean similar terpenes—always check
9. Myrcene dominance often indicates relaxing effects regardless of strain name
10. Medical benefits of terpenes may differ from recreational effects
FAQ
Do terpenes get you high?
Not directly. Terpenes don't bind strongly to CB1 receptors like THC. However, they may modify how THC affects you, potentially enhancing or moderating the high.
Can I buy terpene supplements?
Yes, terpene isolates and blends are available. Some people add them to cannabis or use them in aromatherapy. However, they work best with the natural cannabinoid content of whole-plant cannabis.
Why do some strains smell like diesel or skunk?
These smells come from terpenes (and related compounds called thiols). Diesel smells often come from combinations of myrcene, caryophyllene, and limonene. Skunk aromas involve sulfur compounds.
Are terpenes safe?
Yes, terpenes are generally recognized as safe. They're present in countless foods and products. However, concentrated terpene isolates should be used carefully.
Do indica and sativa actually differ in terpenes?
Research suggests terpene profiles matter more than indica/sativa classification. Many "indicas" are high in myrcene, while many "sativas" are high in limonene or terpinolene—which may explain their different effects.
How can I taste terpenes better?
Use clean glassware, vaporize at lower temperatures, and try the first hit after cleaning your device. Smoke and residue mask delicate terpene flavors.
Do edibles have terpenes?
Most terpenes are lost during decarboxylation and cooking. Some manufacturers add terpenes back to edibles, but they may not affect you the same way as inhaled terpenes.
Conclusion
Terpenes are the hidden key to understanding why different cannabis strains feel different. Moving beyond THC percentages to consider terpene profiles can help you find strains that truly match your needs—whether you're seeking energy, relaxation, focus, or mood elevation.
Start by noting the aromas of strains you enjoy, research their terpene content, and look for patterns. Over time, you'll develop a personal terpene profile that guides better cannabis choices.
