What Are Cannabinoids?
Share
Although cannabis has been used for thousands of years, the scientific understanding of cannabinoids began in the 1960s when THC was first identified. This discovery led to a deeper exploration of other cannabinoids, such as CBD, and the eventual recognition of the endocannabinoid system within the human body. Researchers found that cannabinoids don’t just exist in the cannabis plant—endocannabinoids, which are naturally produced by the human body, perform similar functions.
Since then, scientists have identified over 100 different cannabinoids in cannabis, each with its own unique properties. The discovery of how these compounds work has transformed cannabis from a misunderstood plant into a focal point of medical and wellness research.
The Most Common Cannabinoids Explained
Today, many cannabinoids have become popular for their specific effects. Here’s a breakdown of the most common cannabinoids found in the cannabis plant:
✦ THC (Tetrahydrocannabinol):
The most famous cannabinoid, Delta-9 THC is responsible for the psychoactive high associated with cannabis. It binds directly to CB1 receptors in the brain, producing effects like euphoria, relaxation, and enhanced sensory perception.
✦ Delta-8 THC:
A less potent cousin of Delta-9 THC, Delta-8 produces a more mild, clear-headed high. Its effects are often described as more manageable and less likely to induce anxiety compared to Delta-9.
✦ THCa (Tetrahydrocannabinolic Acid):
THCa is the raw, non-psychoactive form of THC found in fresh cannabis. When exposed to heat, it converts to Delta-9 THC through a process called decarboxylation, unlocking its psychoactive potential.
✦ CBD (Cannabidiol):
CBD is known for its non-psychoactive effects, promoting relaxation, reducing anxiety, and potentially easing inflammation and pain. It doesn’t bind directly to cannabinoid receptors but modulates their activity, influencing the ECS in more subtle ways.
✦ CBN (Cannabinol):
A derivative of THC, CBN is often associated with sedative effects, making it popular for those looking to improve their sleep. CBN forms as THC degrades, which is why aged cannabis tends to have higher CBN levels.
✦ CBG (Cannabigerol):
Known as the “mother of cannabinoids,” CBG is the precursor from which other cannabinoids like THC and CBD develop. Though less abundant, CBG is thought to have anti-inflammatory and neuroprotective properties.
✦ THCV (Tetrahydrocannabivarin):
Often called the “diet weed,” THCV has been reported to act as an appetite suppressant and can provide a stimulating, energizing high without the munchies typically associated with cannabis.
✦ CBC (Cannabichromene):
Though non-psychoactive, CBC is believed to work synergistically with other cannabinoids, enhancing their overall effects through the entourage effect.
✦ HHC (Hexahydrocannabinol):
A hydrogenated form of THC, HHC is thought to produce similar psychoactive effects to THC but with a slightly different potency. Its long-term effects and properties are still under study.
What Are Terpenes?
In addition to cannabinoids, terpenes play a crucial role in cannabis’s effects. These aromatic compounds give cannabis its distinct flavors and scents, from fruity and citrusy to earthy and spicy. Terpenes are found in many plants, including lavender, pine, and citrus fruits.
But terpenes do more than just smell good. They can influence the effects of cannabinoids through the entourage effect. For example, myrcene, a terpene often found in Indica strains, may enhance relaxation, while limonene, common in Sativa strains, may elevate mood and energy levels.
How Do Cannabinoids and Terpenes Work Together?
The beauty of cannabis lies in the interaction between its compounds. Cannabinoids and terpenes work together in what’s called the entourage effect, where the combined effects of these compounds are greater than their individual effects. This is why full-spectrum cannabis products, which contain a variety of cannabinoids and terpenes, are often preferred for both recreational and medicinal use.
For instance, consuming a THC-rich strain with high levels of myrcene may enhance the relaxing effects of THC, creating a more sedative experience. Meanwhile, a Sativa strain with high limonene content may boost energy while THC provides the euphoric high.
Cannabinoids and Drug Testing: What You Need to Know
Cannabinoids, particularly THC and THCa, can show up on drug tests, especially if you're consuming products high in these compounds. Even though CBD itself typically doesn’t result in a positive test, some CBD products may contain trace amounts of THC that could trigger a result.
How long cannabinoids stay in your system varies depending on several factors, including:
- Type of cannabinoid: THC is detectable longer than CBD.
- Consumption method: Smoking or vaping may result in faster detection, while edibles take longer to clear.
- Frequency of use: Regular users tend to retain cannabinoids longer.
- Body composition: Individuals with higher body fat percentages may store THC for longer periods.
Cannabinoids can generally be detected in saliva for up to 24 hours, blood for 1-2 days, urine for 3-30 days, and hair for up to 90 days. These are just estimates, and detection times can vary greatly depending on individual factors.
Conclusion
Cannabinoids are the backbone of the cannabis plant’s therapeutic and recreational effects. Whether you’re seeking the euphoric high of THC, the calming effects of CBD, or the sleep-promoting benefits of CBN, understanding how these compounds work can help you make informed choices about your cannabis use.
As research continues to uncover the diverse range of cannabinoids, their interactions with terpenes, and their potential health benefits, one thing is clear: the world of cannabinoids is vast, complex, and full of possibilities.
