What is Cannabinol (CBN)?
Cannabinol (CBN) is one of over 100 identified cannabinoids found in the cannabis plant. Unlike the major psychoactive cannabinoid tetrahydrocannabinol (THC), CBN does not produce the “high” associated with cannabis.
CBN forms over time as THC is exposed to heat and oxygen. It is considered a minor cannabinoid in fresh cannabis plants but becomes more concentrated as cannabis ages.
While research is still emerging, early studies suggest CBN may have unique effects.
However, most research has been limited to preclinical studies on cells and animals so far. Large, high-quality human trials are still needed.
CBN’s Potential Mechanisms of Action
The exact mechanisms behind CBN’s potential therapeutic effects remain unclear. However, initial studies point to some ways CBN may act in the body:
Interaction with the Endocannabinoid System
Like THC, CBN can bind to cannabinoid receptors CB1 and CB2. These receptors are part of the endocannabinoid system, which helps regulate various functions like sleep, appetite, pain and more.
Early studies show CBN has a lower affinity for CB1 than THC, meaning it binds less strongly. This may contribute to its lack of intoxicating effects.
Enhanced Signaling of Endocannabinoids
Research indicates CBN can inhibit the enzymes that break down endocannabinoids like anandamide. This allows endocannabinoids to remain active longer.
Modulation of TRPV1 Receptors
The TRPV1 receptor is involved in regulating pain, inflammation and temperature sensation. Some research suggests CBN can deactivate TRPV1, which may lead to analgesic and anti-inflammatory effects.
Interaction with 5-HT Receptors
The serotonin system is involved in pain, sleep, anxiety and more. CBN may interact with certain serotonin receptor subtypes, which could contribute to its potential therapeutic effects.
However, its mechanisms of action are complex and require more study.
Factors Influencing CBN’s Duration of Action
When evaluating how long CBN’s effects last, research has looked at its:
These factors determine how quickly CBN is processed and eliminated from the body, which affects its duration of action.
Metabolism of CBN
Like THC, CBN is metabolized in the liver by cytochrome P450 enzymes. There is some evidence that CBN may inhibit cyp34A, an enzyme that helps break down medications. This could potentially lead to negative drug interactions by causing other drugs to accumulate to higher levels in the body.
However, more research is needed on the metabolism of CBN and how it interacts with other drugs and supplements.
Excretion of CBN
Limited studies have looked at how CBN is excreted from the body. Research on THC indicates it can be detected in urine for several weeks after use because it accumulates in fat tissue. This may also be true of CBN, but more studies on excretion rates are needed.
The half-life of a drug refers to the time it takes for its concentration in the blood to be reduced by half through metabolism and excretion.
Studies measuring CBN’s half-life show a high degree of variability. One study found CBN’s half-life ranged from 2.1 - 5.4 hours. Another study showed a broader range of 1.6 - 12 hours.
This wide variation is likely due to differences in factors like measurement methods, individual metabolism, CBN source, and dose. More pharmacokinetic studies are required to establish CBN’s half-life more definitively.
In general, existing data suggests CBN may have a relatively shorter half-life and duration of action compared to THC. But more clinical pharmacology studies in humans are needed.
Duration of CBN Effects Based on Method of Administration
Like other cannabinoids, CBN can be taken through various methods which may impact its onset and duration.
Inhaling CBN through smoking or vaping leads to the fastest onset of action, within 2 to 10 minutes. However, the effects may only last for around 2 to 4 hours.
When CBN is ingested through oils, capsules, gummies or edibles, absorption into the bloodstream is slower. Effects may take 1 to 2 hours to onset. But they typically remain active for a longer duration of 4 to 8 hours.
Applying CBN topically may produce localized effects by interacting with CB receptors in the skin. However, only a small portion may penetrate systemically. The limited data available indicates onset within 30 to 90 minutes and duration up to 6 hours.
The method of taking CBN can impact both how quickly benefits are felt and how long they persist. More human studies are still needed to clarify differences in CBN pharmacokinetics with various administration routes.
CBN Dosage and Duration Considerations
Currently, there are no standardized dosing guidelines for CBN. Research indicates potential benefits with doses ranging from 2.5mg to 20mg. However, more studies are needed to determine optimal therapeutic dosing.
Higher CBN doses do not necessarily result in longer-lasting effects. One study found duration was prolonged with a 10mg dose compared to 20mg. This may indicate that there is a peak threshold dose beyond which effects do not increase.
Individual factors like body chemistry, age, and prior cannabis experience can also influence appropriate CBN dosing and duration. Under medical guidance, methods like starting low and gradually increasing can help find the most effective dose.
CBN Duration Compared to CBD and THC
The duration of CBN also differs compared to the major cannabinoids THC and CBD:
- CBN vs THC: Research indicates THC’s effects can last anywhere from 2 to 6 hours when inhaled and 6 to 12 hours when ingested. Therefore, THC generally has a more prolonged duration than CBN.
- CBN vs CBD: Studies show CBD’s effects may persist for 2 to 6 hours when inhaled and up to 6 hours when consumed orally. This is fairly comparable to CBN’s duration.
However, CBD does not cause the same sedating effects. For sleep support specifically, CBN may have longer-lasting benefits.
Overall current evidence suggests CBN has a relatively shorter duration than THC but a similar duration to CBD. Combining CBN with these other cannabinoids may provide complementary synergistic effects. More clinical studies are still needed.
Factors that May Impact CBN Effects
Several factors can influence how long CBN effects last:
- Dose – Higher doses may prolong duration but only up to a certain threshold.
- Frequency of Use – With regular use, tolerance may develop leading to shorter effects.
- Delivery Method – Inhalation provides faster but shorter effects compared to ingestion.
- Individual Differences – Metabolism, weight, age and more affect CBN action.
- Interactions – Other substances like medications may alter CBN metabolism.
- Time of Day – Sedative effects may be enhanced at night due to circadian rhythms.
These factors can vary the pharmacokinetics and effects of CBN. Monitoring individual response can help determine the ideal regimen.
Developing Tolerances to CBN’s Effects
With sustained use of CBN, some studies suggest users may develop a tolerance and need higher doses to achieve the same effects. More research is still needed on the long-term effects of CBN use.
It’s unclear exactly how tolerance develops. For THC, regular activation of CB1 receptors is believed to play a role. If CBN works through similar mechanisms, taking breaks may help prevent tolerance buildup.
Rotating between different cannabinoids and using targeted “drug holidays” may help mitigate tolerance. However, each individual may respond differently.
Safety and Side Effects of CBN
Current evidence suggests CBN has a relatively low risk of side effects and is well tolerated. Reported adverse effects are minimal and mild. Some potential side effects may include:
- Difficulty concentrating
- Dry mouth
- Reduced blood pressure
Notably, CBN does not appear to cause impairment, anxiety, or paranoia like THC. However, combining CBN with alcohol or other sedatives can increase drowsiness and sedation.
Start with low doses of CBN and monitor individual response. Consult a doctor before use if taking other medications or supplements to check for possible interactions.
While considered safe based on initial research, the long-term effects of CBN need further investigation. It remains unregulated and more studies are required to confirm its safety profile with chronic use.
The Future of CBN Research
Research into the therapeutic potential of CBN is still in early stages. Some areas future studies may provide more insight on include:
- CBN’s mechanisms of action and how it interacts with the endocannabinoid system.
- CBN’s metabolism including breakdown, excretion rates, and half-life determination.
- Optimal dosing regimens for different delivery methods and health conditions.
- Long-term effects and safety with sustained use.
- Development of tolerance and potential drug interactions.
- Clinical trials comparing CBN to placebo and other cannabinoids.
As research continues, a clearer picture will emerge on CBN’s pharmacology, duration of benefits, and proper therapeutic use.
