The Terpenes of Cannabis, Their Aromas, and Effects
THC activates the CB2 receptor, which regulates immune function and the peripheral nervous system. But this is not the reason people feel stoned when they smoke marijuana; instead, what causes the high is THC binding to the CB1 receptor, which is concentrated in the brain and the central nervous system. Stimulating the CB2 receptor doesn’t have a psychoactive effect because CB2 receptors are localized predominantly outside the brain and central nervous system. CB2 receptors are present in the gut, spleen, liver, heart, kidneys, bones, blood vessels, lymph cells, endocrine glands, and reproductive organs. Marijuana is such a versatile medicinal substance because it acts everywhere, not just in the brain.
In 2008, the Swiss scientist Jürg Gertsch documented beta-caryophyllene’s binding affinity for the CB2 receptor and described it as “a dietary cannabinoid.” It is the only terpenoid known to directly activate a cannabinoid receptor (which is one of the reasons why green, leafy vegetables are very healthy for people to eat). The dual status of beta-caryophyllene as a terpenoid and a CB2 activator underscores the synergistic interplay between various components of the cannabis plant. There are many, many chemical compounds in marijuana, including cannabinoids, terpenoids and flavonoids (which give fruit skin its color). Each has specific medicinal attributes, which combine to create a holistic “entourage effect,” so that the therapeutic impact of the whole plant is greater than the sum of its parts. Certain terpenoids dilate capillaries in the lungs, enabling smoked or vaporized THC to enter the bloodstream more easily. Nerolidol, a sedative terpenoid, is a skin penetrant that increases permeability and potentially facilitates cannabinoid absorption when applied topically for pain or skin conditions. Terpenoids and cannabinoids both increase blood flow, enhance cortical activity and kill respiratory pathogens – including MSRA, the antibiotic-resistant bacteria that in recent years has claimed the lives of tens of thousands of Americans. Dr. Russo’s article reports that cannabinoid-terpenoid interactions “could produce synergy with respect to treatment of pain, inflammation, depression, anxiety, addiction, epilepsy, cancer, fungal, and bacterial infections.”
Marijuana’s bouquet of terpenes – that “riot of perfumes,” as the poet (and hashish eater) Arthur Rimbaud once said – plays another important role: Terpenes buffer THC’s psychoactivity. Cannabinoid and Terpenoid interactions can amplify the beneficial effects of cannabis while reducing THC-induced anxiety. Some people can’t handle THC dominant marijuana, while others enjoy the relaxed intensity of the cannabis high. However, Most everyone would prefer organically grown bud with its tangy, antioxidant-rich mixture of cannabinoids, terpenoids and flavonoids, as opposed to Marinol, the pure synthetic-THC pill. For nearly everyone who has tried both, the experience of THC alone compares poorly to that of THC combined with terpenes and other components of the cannabis plant.
According to several sources, eating a good ripe mango 45 minutes before smoking cannabis increases the effect of the herb. This could be explained by the presence of Myrcene in mangos, which acts in synergy with the THC. However, you should select a very good variety of mango, because only a few have essential oil rich in myrcene (Cavalo 57.1%, Rose 52.4%, Sword 37.2% and Paulista 30.3%) Also, if the mango is not very ripe the myrcene level will be too low to notice its interaction.
THC and the other cannabinoids have no odor, so the cannabis fragrance depends on which terpenes predominate. Thus far, focus has only been placed in one area or another... first THC, now CBD. I believe this is foolish as I intend to show that many many compounds contribute to the healing properties of the plant. To focus on only one aspect is a waste of time. Chemically extracting or isolating the healing properties from single compounds simply cannot be done with cannabis due to the various terpene mixes and the fact that most terpenes have healing properties that also follow the "entourage effect".
It's not just about THC or CBD. Cannabis is a mix of many different compounds. Most of them fall into three categories: cannabinoids, terpenoids, and flavanoids. Each of these compounds can significantly modify the therapeutic benefits of the plant. There are hundreds of different chemical combinations each producing a different effect. Meschler and Howlett (1999) discussed several mechanisms by which terpenoids modulate THC activity. For instance, some terpenoids bind to cannabinoid receptors sequestering THC by perturbing annular lipids surrounding the receptor, or by increasing the fluidity of neuronal membranes, and increasing cell wall permeability. Other terpenoids alter the signal by remodeling G-proteins. And then there are terpenoids that alter the pharmacokinetics of THC itself. Terpenoids may also act on other receptors and neurotransmitters. Some terpenoids act as serotonin uptake inhibitors (as does Prozac), some enhance norepinephrine activity (as do tricyclic antidepressants), some increase dopamine activity (as do monoamine oxidase inhibitors and bupropion), and some augment GABA (as do baclofen and the benzodiazepines).

AEA (Anandamide) is an often missed endocannabinoid found in the human body. Anandamide is the brain's own THC (just like "endorphin" is the brain's own morphine). Anandamide has only been found in two plants - Cacao (chocolate) and Cannabis. The name Anandamide is taken from the Sanskrit word (and Hinduistic religious term) ananda, which means "joy, bliss, delight", and amide.
Anandamide regulates the functions of our central nervous system and our immune system. AEA regulates appetite, memory, sensations of pleasure and pain, our immune system, and sleep patterns. It also inhibits certain cancers, such as breast cancer in humans. It is used in the drug therapy of hypertension and cerebrovascular spasms, as myocardial protective agents, and in the relaxation of uterine spasms. Research suggests that anandamide plays a role in the making and breaking of short-term connections between nerve cells, and this is related to learning and memory. Animal studies suggest that too much anandamide induces forgetfulness. This suggests that if substances could be developed that keep anandamide from binding to its receptor, these substances might be used to treat memory loss or even to enhance existing memory.
THC and the other cannabinoids have no odor.
Terpenes
Buchbauer et al. (1993) assayed the sedative effects of over 40 terpenoids upon inhalation by mice; linalool was the most powerful, reducing mouse motility 73% after 1 hour of inhalation. The study demonstrated that other terpenoids found in cannabis, such as citronellol and α-terpineol, are also deeply sedating upon inhalation, even in low concentrations. Furthermore, combinations of these terpenoids are synergistic in their sedative effects. These terpenoids may mitigate the anxiety provoked by pure THC. Inhalation of such terpenoids also provides antidepressant effects (Komori et al. 1995).
β-Myrcene has an odor that is variously described as an aroma of hops, clove like, earthy, green-vegatative, citrus, fruity with tropical, mango and minty nuances. The various odors are the result of slight differences in the overall makeup. All of these flavors and odors are commonly used to describe Cannabis.
β-Myrcene is the most prevalent terpene found in most varieties of marijuana but it is not found in hemp. It is present in significant concentrations in cannabis resin itself. It is also found in mango, hops, lemon grass, East Indian bay tree, and verbena. Because of its appealing fragrance, myrcene is used extensively in the perfume industry. Myrcene has antimicrobial, antiseptic, analgesic, antioxidant, anticarcinogen (It blocks the actions of cytochrome, aflatoxin B and other pro-mutagens that are implicated in carcinogenesis.) and anti-inflammatory properties. It has shown some promise when used as an antidepressant, or as an additive to other antidepressant drugs and is also used in massage therapy as a muscle relaxer.
Myrcene is a synergist of THC: A combination of the two molecules creates a stronger experience than THC alone. Myrcene affects the permeability of the cell membranes, thus it allows more THC to reach brain cells and increase the absorption of other terpenes. This terpene contributes strongly to the infamous “couch-lock” experience.

Capsaicin in its pure form is odorless. It is an irritant for mammals, known for the sensation it provokes when inhaled, eaten, or applied to the skin. In this sense, it is similar to menthol (which stimulates the bodys sensors without causing an actual change in temperature). Capsaicin is used as an analgesic in topical ointments and dermal patches to relieve pain and as an anti-inflammatory.
Δ-3-Carene has a medium strength, sweet, pungent citrus odor. It is a constituent of pine and cedar resin but is found in many other plants including rosemary. In aroma therapy, cypress oil, high in D-3-Carene, is used to dry excess fluids, tears, running noses, excess menstrual flow and perspiration. It is thought to be at least partially responsible for the dry mouth and eye problems that are common side effects experienced by some cannabis users.

β-Caryophyllene has a sweet, woody and dry clove odor and tastes pepper spicy with camphor and astringent citrus backgrounds. It is a major terpene found in black pepper, clove and cotton. It is found in smaller %'s in many other green, leafy vegetables, herbs, and spices. Caryophylene contributes to black pepper's spiciness. Caryophylene oil is also used industrially to enhance tobacco flavor.
Caryophylene, given in high amounts, is a calcium and potassium ion channel blocker. As a result, it impedes the pressure excerted by heart muscles. As a topical it is analgesic and is one of the active constituents that makes clove oil, a preferred treatment for toothache. It does not seem to be involved in mood change, however caryophyllene shows great promise in a salve or lotion as a therapeutic compound for inflammatory conditions and autoimmune disorders because of its ability to bind directly to the peripheral cannabinoid receptor CB2.

Limonene is found in high amounts in cannabis resin as well as tropical fruit rinds and many other fruits and flowers. Everyone is familiar with the odor of citrus resins. They explode into the air when a fruit is peeled. The exact odor is determined by the structure of the terpene. Plants use Limonene to repulse predators. For instance, flies have a group of receptors similar in function to the taste buds on our tongues. One of them detects noxious chemicals, and responds to Limonene as if it were toxic. This is hard wired into the flies brain. Limonene is a potent antibacterial, antifungal and anticancer agent. Limonene has been used clinically to dissolve gallstones, improve mood and relieve heartburn and gastrointestinal reflux. Limonene has been shown to destroy breast-cancer cells in lab experiments, and its powerful antimicrobial action can kill pathogenic bacteria. Limonene sprays are also used to treat depression.
Limonene is the second, third or fourth most prevalent terpene in almost all cannabis resins and it is a precursor to the synthesis of other cannabinoids. Limonene is highly absorbed by inhalation and quickly appears in the bloodstream. Since Limonene is known to affect the permeability of the cell membranes, it allows more THC to reach brain cells and increases the absorption of other terpenes. Limonene's design facilitates a direct response by quickly permeating the blood-brain barrier. The result is increased systolic blood pressure. One test, reported subjective alertness and restlessness.
Linalool has a floral scent reminiscent of spring flowers such as lily of the valley, but with spicy overtones. It is a terpenoid prominent in lavender. It is refined from lavender, neroli, and other essential oils. Humans can detect its odor at rates as low as one part per million in the air.
Linalool is being tested now for treatment of several types of cancer. It is also a component of several sedating essential oils including lavender oil which is believed to possess antianxiety and sedative properties. In tests on humans who inhaled it, it caused severe sedation. In tests on lab rats it reduced their activity by almost 75%. In addition to being a compound that counters anxiety and mediates stress, linalool is a strong anticonvulsant, and it also amplifies serotonin-receptor transmission, conferring an antidepressant effect.

α-Pinene is the familiar odor associated with pine trees and their resins. It is the major component in turpentine and is found in many other plant essential oils in noticeable amounts including rosemary, sage, eucalyptus and many others. Pinene is used medically as an expectorant, and topical antiseptic. It easily crosses the blood-brain barrier where it acts as a acetylcholinesterase inhibitor; that is, it inhibits activity of a chemical that destroys an information transfer molecule. This results in better memory. Pinene also promotes alertness and memory retention. Largely due to the presence of pinene, rosemary and sage are both considered "memory plants." Concoctions made from their leaves have been used for thousands of years in traditional medicine to retain and restore memory. It is also a bronchodilator. A pharmacokinetics study of inhaled α-pinene in humans demonstrated 60% uptake, and a relative bronchodilation effect. The smoke seems to expand in your lungs and the high comes on very quickly since a high percentage of the substance will pass into the bloodstream and brain. It also increases focus, self satisfaction and energy, which generally counteracts with the presence of Terpineol. α-Pinene has inhibited acetylcholinesterase suggesting utility in the clinical treatment of Alzheimer’s disease.

Pulegone has a minty-camphor odor and flavor that is used in the candy industry. It is implicated in liver damage in very high dosages. Pulegone is an acetylcholinesterase inhibitor. Thus, it stops the action of the protein that destroys acetylcholine, which is used by the brain to store memories. It may counteract THC's activity, which leads to low acetylcholine levels. The result is that you would forget more on THC alone than you would on THC accompanied by Pulegone.

α-Terpineol has a lilac, citrus or apple blossom to lime odor. It is used extensively in the perfume industry. Terpineol however, is often found in cannabis with high pinene levels. Therefore, its odor is very often masked by the pungent aromas of pinene. It is a minor constituent of many plant essential oils. It is also used in soaps for fragrance. It reduces the capability for movement by 45% in lab rat tests. It was also shown to be deeply sedating upon inhalation. This may partially account for the couchlock effects of some cannabis although it is not usually associated with body highs.

The main differences between terpene profiles of evaluated strains belonging to the two principal biotypes are:
‘mostly indica’ strains were characterized by dominancy of β-myrcene, present in high relative contents, with limonene or α-pinene as second most abundant terpenoid
‘mostly sativa’ strains were characterized by more complex terpene profiles, with some strains having α-terpinolene or α-pinene as dominant terpenoid, and some strains having β-myrcene as dominant terpenoid with α-terpinolene or trans-β-ocimene as second most abundant terpenoid.
Breeding for specific terpenoids in plants is a fascinating research topic. In fact, the various biological activities of these compounds make the analysis of terpenoids a valuable tool for improving a considerable number of traits in cultivars of Cannabis.
Testing for these terpines is like making a recipe-book for a Chef. They tell you what the ingredients are in the dish, and in which quantities.
The “Entourage effect” of Cannabis.
The clinical contribution of cannabinoids different than THC, terpenoids and flavonoids to clinical cannabis effects has been espoused as an “entourage effect” (Mechoulam and Ben-Shabat 1999). While THC remains the most psychoactive compound found in Cannabis, all other substances present in the plant (in particular cannabinoids, terpenoids and flavonoids) also have unique properties that will ultimately influence the effects that Cannabis has on us.
Many times patients using Cannabis as medicine have reported that a specific plant genetic seems to have better therapeutic properties on them than other ones available. When compared, those Cannabis varieties had similar cannabinoid profile (content of cannabinoids such as THC and CBD). So if the difference is not in the cannabinoid content, it must lie in the “entourage” of other substances present in the plant in order to explain the difference perceived by various patients.
