Lesson 3
Cannabis is more than just one compound or effect. At the heart of its therapeutic potential are two key families of compounds: cannabinoids and terpenes. These natural substances work in harmony to produce the wide range of effects that cannabis is known for.
Cannabinoids are active compounds that interact with the body’s endocannabinoid system, a complex network of receptors that helps regulate pain, mood, inflammation, appetite, sleep, and more. While THC is the most well-known cannabinoid, it’s just one piece of the puzzle. Cannabis contains over 100 different cannabinoids, many of which are non-intoxicating but still profoundly therapeutic. These compounds don’t work in isolation. Thanks to what’s known as the entourage effect, cannabinoids like CBD can actually soften or enhance the effects of THC. For example, CBD may reduce the anxiety or paranoia sometimes caused by THC, while CBN can deepen its calming effects.
Terpenes are the aromatic oils that give cannabis its unique smell and flavor, but their role goes far beyond aroma. These plant compounds are biologically active, influencing how cannabinoids are absorbed and how they feel in the body. In fact, some terpenes, like beta-caryophyllene, can act like cannabinoids themselves. Terpenes can enhance absorption, reduce side effects, and even help target cannabinoids to specific areas of the brain or body. Together, cannabinoids and terpenes create a therapeutic synergy that’s greater than the sum of its parts.
THC is the primary intoxicating compound in cannabis—the one responsible for the "high." But it does much more than create euphoria. THC has powerful potential as a pain reliever, sleep aid, anti-inflammatory, and anti-nausea agent. It may also reduce muscle spasms, improve appetite, and protect the brain. Individual responses to THC can vary widely, which is why starting with a low dose and gradually increasing is often recommended.
CBD is non-intoxicating and widely known for its calming and therapeutic effects. It can reduce anxiety, inflammation, and seizures, and may help with mood disorders, pain, and even bone growth. Unlike THC, CBD does not build tolerance—in fact, some patients respond better to lower doses over time. It’s psychoactive in the sense that it affects the brain and mood, but it won’t make you feel "high".
CBG is often referred to as the “mother cannabinoid” because it’s the precursor to THC and CBD. Though typically found in smaller amounts, CBG is a potent compound with antibacterial, antidepressant, and neuroprotective properties. It’s shown promise in treating inflammation, skin disorders, and digestive issues, and is often described as alerting or energizing, rather than sedating.
CBN forms as THC breaks down over time, which is why it’s often found in aged cannabis. Though mildly psychoactive, it’s not especially intoxicating on its own. CBN is believed to enhance THC’s sedative effects, making it a popular compound in sleep formulas. It also has potential for pain relief, appetite stimulation, and neuroprotection.
THCA is the raw, unheated form of THC. It’s abundant in fresh cannabis and converts to THC when exposed to heat (a process called decarboxylation). THCA is non-intoxicating and difficult to study due to its instability, but early research suggests it may have anti-inflammatory, anti-nausea, and neuroprotective effects.
A note about THCA:
Because most cannabis laws only restrict delta-9 THC, many hemp companies have begun selling THCA-rich flower that falls below the federal limit of 0.3% delta-9 THC. This legal gray area has enabled the sale of potent products in states where cannabis remains illegal. While THCA remains federally legal under current definitions, some states have started regulating or banning THCA by including all forms of THC forms—both active and potential—in their laws.
The acidic precursor to CBD, CBDA is found in raw cannabis flower and converts to CBD when heated. Once thought to be inactive, it’s now being recognized for its anti-anxiety, anti-inflammatory, and anti-nausea properties—especially in raw or juiced cannabis preparations.
A non-intoxicating cannabinoid related to CBD, CBDV is gaining attention for its anticonvulsant properties. Early animal studies suggest it could help with epilepsy and nerve pain, especially when used alongside CBD.
THCV is structurally similar to THC and may suppress appetite, improve blood sugar regulation, and reduce seizures. It’s also being studied for its potential in neurodegenerative diseases like Parkinson’s. Some research suggests it can reduce THC’s psychoactive effects, offering a more balanced experience.
Non-intoxicating and often overlooked, CBC contributes to cannabis’s anti-inflammatory and mood-enhancing effects. When paired with THC or CBN, CBC may enhance pain relief and even elevate THC levels in the brain. It also shows promise for acne, fungal infections, and cancer-related research.
A close chemical cousin to THC, delta-8 provides similar benefits with a gentler, less intoxicating effect—making it attractive to patients who want symptom relief without feeling overly high. It’s known for reducing pain, stimulating appetite, and easing nausea.

Beta-myrcene is one of the most abundant terpenes in cannabis and is known for its earthy, musky aroma with hints of ripe fruit. Often associated with deeply relaxing and sedating effects, myrcene is frequently found in strains used for pain relief, stress, and sleep. It also has anti-inflammatory, antioxidant, and muscle-relaxant properties. Some researchers believe its presence may be key in promoting the classic “couch-lock” sensation.
Limonene gives cannabis its bright citrus scent and is also found in the rinds of lemons, oranges, and other fruits. Known for its uplifting and mood-enhancing effects, limonene may help reduce stress, anxiety, and depression. It also has antifungal, antibacterial, and potential anticancer properties. Limonene is often found in strains associated with mental clarity, energy, and a sense of well-being.
Beta-caryophyllene stands out from other terpenes because it can directly bind to CB2 receptors in the endocannabinoid system, giving it cannabinoid-like effects. It has a peppery, spicy aroma and is commonly found in black pepper, cloves, and oregano. Known for its strong anti-inflammatory and pain-relieving properties, beta-caryophyllene may also support immune function and has shown promise in managing anxiety and addiction.
Alpha-pinene has a sharp, pine-like aroma and is one of the most common terpenes in nature, found in pine needles, rosemary, and basil. It’s known for promoting alertness and supporting memory function. In addition to its cognitive benefits, alpha-pinene has bronchodilating, antimicrobial, and anti-inflammatory properties. It’s often found in strains associated with focus, creativity, and clear-headed effects.
Beta-pinene shares its sharp, pine-like aroma with its sibling alpha-pinene but tends to have a slightly more herbal, woody scent. It’s found in many of the same plants—like rosemary, parsley, and basil—and is often present in cannabis alongside alpha-pinene. Beta-pinene has strong antimicrobial properties and may also support cognitive function and memory. It’s believed to help offset some of the short-term memory loss associated with high-THC cannabis strains and is a useful terpene for those seeking mental clarity and focus.
Linalool carries a soft, floral scent reminiscent of lavender and is well-known for its calming and sedative effects. Found in lavender, mint, and rosewood, linalool is often used for stress, anxiety, and sleep support. It also shows anticonvulsant and anti-inflammatory potential and may help modulate the body’s response to pain. Strains with linalool are often sought after for relaxation and emotional balance.
Humulene has an earthy, woody aroma that’s often associated with hops—the same plant used to flavor beer. Found in cannabis, cloves, and basil, humulene is known for its anti-inflammatory and antibacterial effects. It may also suppress appetite, making it an interesting contrast to other cannabis compounds that increase hunger. Humulene is often found in strains that promote a calm body without strong sedation.
Ocimene is a sweet, herbaceous terpene found in basil, mint, and mango. Often linked to uplifting and energizing effects, ocimene may help enhance creativity or focus. Although research is still emerging, ocimene has demonstrated antiviral, antifungal, and anticonvulsant activity in essential oil studies. It also contributes to a plant’s natural defense system, helping repel pests.
Terpinolene is a terpene with a complex aroma—a mix of pine, citrus, and floral notes. Unlike more sedative terpenes, terpinolene is often associated with alertness or mental clarity in people, despite showing calming effects in animal models. It has antioxidant, antibacterial, and antifungal properties, and early studies suggest potential anticancer activity. It’s commonly found in "sativa-dominant" cannabis.
Alpha-bisabolol, also found in chamomile, has a delicate floral aroma and is well known for its soothing properties. It’s commonly used in skincare for its anti-inflammatory, antimicrobial, and wound-healing benefits. In cannabis, alpha-bisabolol is associated with gentle, calming effects and may help reduce irritation, inflammation, or discomfort when used in topicals or tinctures.
Eucalyptol has a fresh, minty scent and is the main terpene found in eucalyptus trees. Though present in small amounts in cannabis, it offers big benefits. Eucalyptol is known for its antimicrobial, anti-inflammatory, and pain-relieving properties. It may also support memory and cognitive function, and is being studied for potential roles in treating Alzheimer’s disease. You’ll find it in strains with crisp, cooling aromas.
Nerolidol has a soft floral and citrusy aroma and is found in jasmine, lemongrass, and tea tree. This terpene is known for its relaxing, sedative effects and is often used to support sleep or stress relief. It also shows promise as an antifungal, antioxidant, and antimicrobial compound. Nerolidol may enhance skin absorption, making it useful in topical formulations and transdermal cannabis products.
Beta-caryophyllene oxide is the oxidized version of beta-caryophyllene and carries a spicy, herbal scent with earthy undertones. It's found in lemon balm, cloves, and eucalyptus, and is notably one of the compounds that drug-sniffing dogs are trained to detect. Like its precursor, it shows anti-inflammatory and antifungal activity—particularly in treating fungal nail infections. Recent studies suggest it may act as a strong CB2 receptor agonist and be even more effective than beta-caryophyllene in reducing alcohol consumption in animal models, pointing to potential in addiction treatment and immune regulation.
Delta-3-carene has a sweet, cedar-like aroma and is found in rosemary, basil, and pine. This terpene is being studied for its role in bone health and inflammation, particularly in conditions like arthritis and osteoporosis. It may also support memory retention and cognitive function, with potential applications in neurodegenerative disorders. Though more research is needed, carene shows exciting promise for both body and mind.
Camphene smells like fir needles and damp woodlands. It’s commonly used in traditional medicine for its antioxidant and anti-inflammatory effects, especially when paired with vitamin C. Camphene has shown potential for supporting cardiovascular health by lowering cholesterol and triglyceride levels. It’s also used topically to ease skin issues like eczema and psoriasis, offering soothing and protective benefits.
Borneol has a cool, minty-herbal aroma and is found in plants like mint, rosemary, and camphor. Traditionally used in Chinese medicine, it has natural insect-repellent properties and is currently being studied for its anticancer effects. Borneol may also help other compounds cross the blood-brain barrier, potentially enhancing the effectiveness of cannabinoids and other plant compounds.
Terpineol has a floral, lilac-like aroma with subtle citrus and mint notes. Known for its relaxing effects, this terpene is thought to contribute to the "couch-lock" sensation in some cannabis strains. Terpineol also has antioxidant, antimicrobial, and anti-inflammatory properties. It’s widely used in perfumes and cosmetics for both its scent and skin-friendly benefits.
Valencene brings a sweet, citrusy scent to the cannabis aroma profile and is named after Valencia oranges. Known for its mood-lifting and energizing effects, valencene also acts as a natural insect repellent. It may have anti-inflammatory and skin-protective properties as well. It’s a popular terpene in strains that feel bright, uplifting, or summery.
Geraniol smells like roses, peaches, and plums. It’s found in lemongrass, tobacco, and many fragrant herbs. In addition to its sweet, floral fragrance, geraniol may offer antioxidant and neuroprotective effects. It’s commonly used in aromatherapy, bath products, and lotions, and may help fight oxidative stress and support brain health.
Phytol has a mild, grassy scent and is more abundant in green tea than cannabis, though it appears in trace amounts in some strains. It’s used industrially in the production of vitamins E and K1 and has shown potential as an anti-inflammatory, antioxidant, and antitumor agent. Phytol may also help reduce anxiety and act as a gentle sedative, supporting relaxation and stress relief.
