Myrcene is the most abundant terpene in modern cannabis, found in over 40% of strains. It's associated with deeply relaxing, sedating 'couch-lock' effects and is believed to enhance THC's ability to cross the blood-brain barrier, potentially intensifying its psychoactive effects. Myrcene-dominant strains are typically indica-leaning and favored for evening use, pain relief, and sleep support. The folk remedy of eating a mango before consuming cannabis is based on myrcene's presence in mangoes.

Limonene is associated with mood elevation, stress relief, and anti-anxiety effects. It's the terpene responsible for the uplifting, energetic qualities of many sativa and sativa-dominant hybrid strains. Research suggests limonene may improve absorption of other terpenes and chemicals through the skin and digestive tract, making it a key player in the entourage effect. It also shows potential antifungal and antibacterial properties.

Caryophyllene is unique among terpenes because it directly binds to CB2 cannabinoid receptors in the immune system, making it the only terpene that acts as a functional cannabinoid. This gives it potent anti-inflammatory properties without psychoactive effects. It's one of the most therapeutically promising terpenes, with studies showing potential for anxiety reduction, pain relief, and even alcohol craving reduction.

Linalool is the terpene responsible for lavender's calming reputation. In cannabis, it contributes to relaxing, anti-anxiety effects and is often prominent in strains used for stress relief and sleep. Research has shown linalool may have anticonvulsant, anti-inflammatory, and analgesic properties. It's also being studied for potential neuroprotective effects against Alzheimer's disease.

Pinene is the most widely occurring terpene in nature and is responsible for the classic 'pine' aroma in many cannabis strains. It's associated with alertness, memory retention, and mental clarity — potentially counteracting some of THC's short-term memory effects. Pinene acts as a bronchodilator, opening airways, which may explain why certain strains feel 'easier to breathe' than others. It also has notable anti-inflammatory properties.

Humulene gives beer its signature hoppy character and contributes earthy, woody notes to cannabis. Unlike most cannabinoids and many terpenes, humulene is associated with appetite suppression rather than stimulation, making it notable for consumers who want to avoid the 'munchies.' It also shows anti-inflammatory and antibacterial properties in research, and works synergistically with caryophyllene to enhance pain-relieving effects.

Terpinolene is the least common of the major cannabis terpenes but produces distinctive effects when it's the dominant terpene. Strains high in terpinolene tend to be uplifting and energetic, often associated with sativa-dominant varieties. Despite its energizing reputation, high doses may have sedative effects. Terpinolene also shows antioxidant and potential antifungal properties in research.

Ocimene is a sweet, herbaceous terpene that contributes to the complex aroma profiles of many cannabis strains. It's been studied for antifungal, antiviral, and anti-inflammatory properties. In cannabis, ocimene tends to appear in uplifting, sativa-leaning strains and contributes to the 'sweet' aromatic notes often described in tropical and fruity strain profiles.
