Exploring the World of Alt Cannabinoids: The Sleepy Cannabinoid
The world of cannabis is a vast and intricate landscape, filled with an array of compounds and strains that offer distinct effects and benefits. While THC and CBD have garnered significant recognition and popularity, there are other lesser-known cannabinoids that are equally deserving of exploration. One promising cannabinoid is CBN, or cannabinol, which is gaining attention for its potential sleep-promoting properties.
CBN is a minor cannabinoid that is produced as THC, the psychoactive compound in cannabis, degrades over time. When THC is exposed to air and light, it undergoes a process called oxidation, which converts it into CBN. This is why older cannabis tends to have higher levels of CBN than fresher cannabis and it is also why the brown nugs from bud left out have a very different effect when smoked.
The Sleepy Molecule
Unlike THC, CBN is not very psychoactive, meaning it does not produce the “high” associated with cannabis use. Some studies report a slightly psychoactive effect, typically less than 30% of THC, but most users report not feeling anything in the way of a “high”. Instead, it is known for its sedative and relaxing effects.
Many users report that CBN helps them fall asleep faster and stay asleep longer, making it a popular choice for those suffering from insomnia or other sleep disorders. Studies have shown that CBN can help to prolong sleep duration and improve sleep quality. In one study, researchers found that rats given CBN had longer periods of REM sleep and less wakefulness during the night, making it a viable alternative to more popular sleep remedies such as melatonin, which have several side effects such as drowsiness, headache, nausea, dry mouth, daytime sleepiness, mood changes and hyper-vivid dreams. For cannabis smokers, this is sometimes a frightening return to the world of dreams since THC is widely known to reduce or entirely eliminate memorable dreaming.
CBN and melatonin are both compounds that have been found to promote sleep, but they work in different ways. CBN is a cannabinoid that interacts with the endocannabinoid system (ECS), a complex network of receptors and signaling molecules that helps regulate various physiological processes, including sleep. Because CBN works through the endocannabinoid system rather than directly on the brain, it may help to promote sleep by reducing wakefulness and increasing the duration of sleep. In contrast, melatonin is a hormone that is produced naturally by the body in response to darkness. It helps regulate the sleep-wake cycle by signaling to the body that it is time to sleep. Melatonin works by binding to specific receptors in the brain, which can help to reduce the time it takes to fall asleep, increase the duration of sleep, and improve sleep quality. While both CBN and melatonin have been found to promote sleep, they work through different mechanisms and may have different effects on the body. Additionally, melatonin is a hormone that is produced naturally by the body, in response to specific environmental cues, while CBN is a compound that is found in cannabis plants and works through the complex ECS.
How does CBN even work?
The endocannabinoid system (ECS) helps regulate various functions such as sleep, appetite, mood, and pain. The ECS has receptors throughout the body that interact with cannabinoids, which are compounds found in cannabis plants and others like chocolate, as well as endocannabinoids, which are naturally produced by the body.
One of the receptors in the ECS is the CB1 receptor, which is primarily found in the brain and central nervous system. THC, the psychoactive compound in cannabis, binds to the CB1 receptor, producing the “high” associated with cannabis use. CBN, on the other hand, interacts with the CB1 receptor differently.
At low doses, CBN has a weak affinity for the CB1 receptor and does not produce any psychoactive effects. However, at higher doses, CBN can act as a CB1 receptor agonist, meaning it binds to the receptor and activates it, producing sedative effects. According to a recent study, CBN has been found to be effective in reducing wake after sleep onset minutes in participants with insomnia disorder. The study, which was a randomized, double-blind, placebo-controlled, found that a single fixed oral liquid dose of 30 mg CBN reduced wake after sleep onset minutes compared to placebo. Additionally, CBN has been found to increase the duration of sleep in rats, suggesting that it may have sedative properties.
Among the minor cannabinoids found in Cannabis sativa, cannabinol (CBN) has shown particular promise for its antimicrobial properties. A study conducted by Appendino et al. (2008) demonstrated that CBN, along with other cannabinoids, exhibited potent activity against methicillin-resistant Staphylococcus aureus (MRSA), a bacterium that is highly resistant to antibiotics and poses a significant threat to public health. The study found that CBN was effective at inhibiting the growth of MRSA, suggesting that it may have potential as an alternative treatment for antibiotic-resistant infections. The mechanism by which CBN exerts its antimicrobial effects is not fully understood, but it is thought to involve disruption of the bacterial cell membrane and inhibition of biofilm formation. Further research is needed to fully understand the potential of CBN as an antimicrobial agent and to determine its safety and efficacy in clinical settings. Nevertheless, these findings suggest that CBN, like other minor cannabinoids, may have significant therapeutic potential beyond its sleep-promoting effects.
CBN also interacts with other receptors in the body, such as the CB2 receptor, which is primarily found in the immune system. By activating the CB2 receptor, CBN may help to reduce inflammation and pain, making it a potential treatment for conditions such as arthritis.
In addition to its effects on the ECS, CBN has also been shown to interact with other systems in the body, such as the serotonin system, which is involved in regulating mood and sleep. By activating the 5-HT1A receptor, CBN may produce an antidepressant effect, making it a potential treatment for conditions such as depression and anxiety.
A Bright Green Future
Because of the explosion of cannabis research due to the relaxation of prohibitive laws and regulations, we are just beginning to understand the full potential of cannabinoids like CBN. As more studies are conducted and our understanding of CBN deepens, it is likely that we will see an increase in demand for this unique cannabinoid. With its potential sleep-promoting properties, antimicrobial effects, and other therapeutic benefits, CBN may become an important player in the world of cannabis and alternative medicine. As the cannabis industry continues to evolve, we can look forward to a future where the full potential of cannabinoids like CBN is realized.
