Researchers from The Salk Institute for Organic Research in California have found how hashish can shield towards Alzheimer’s. Most earlier analysis has targeted on THC and CBD compounds, however little is understood concerning the non-psychoactive compound cannabinol (CBN).
Of their newest analysis, Salk scientists have uncovered how this therapeutic compound may also help stop nerve harm and cell demise. They recommend that CBN may probably deal with neurodegenerative ailments like Alzheimer’s and Parkinson’s. Their findings have been printed within the journal Free Radical Biology and Drugs on January 6, 2022.

“We’ve discovered that cannabinol protects neurons from oxidative stress and cell demise, two of the main contributors to Alzheimer’s,” says senior creator Pamela Maher, a analysis professor and head of Salk’s Mobile Neurobiology Laboratory. “This discovery may someday result in the event of recent therapeutics for treating this illness and different neurodegenerative issues, like Parkinson’s illness.”
Cannabinol comes from the hashish plant and resembles THC molecularly. Nevertheless, it differs because it’s not psychoactive and isn’t as closely regulated by the FDA. Prior analysis by Maher’s lab found that CBN protects the mind, however they weren’t certain how till this examine. Now, they’ve uncovered the mechanism driving CBN to guard mind cells from oxidative harm and demise.
CA Researchers Discover Hashish Might Assist Forestall Parkinson’s and Alzheimer’s
Within the examine, Maher’s colleagues examined the method of oxytosis or ferroptosis. These are cell demise pathways in neuronal cells within the growing older mind. The method begins with the depletion of an antioxidant known as glutathione and leads to the eventual demise of mind cells resulting from lipid oxidation.
This free radical response happens between fatty acids and oxygen within the mind, ravenous cells of oxygen. Mounting proof exhibits that oxytosis could also be a key driver of Alzheimer’s illness.
The crew launched cannabinol to nerve cells within the examine, adopted by a compound to induce oxidative harm. They found that the CBN helped shield our physique’s mitochondria, the “power powerhouse” inside neurons. In cells broken by oxidation, mitochondria curl up in a form that resembles donuts.
Scientists have famous this alteration in dying cells within the brains of these with Alzheimer’s illness. Nevertheless, treating cells with cannabinol stopped the mitochondria from curling up and ensured they continued functioning.
To confirm the therapeutic results of CBN on mitochondria, researchers reproduced the experiment in nerve cells with out mitochondria. In these cells, CBN didn’t have the identical protecting affect.
“We have been in a position to instantly present that upkeep of mitochondrial perform was particularly required for the protecting results of the compound,” Maher stated.
In one other very important discovery, researchers discovered that CBN didn’t set off cannabinoid receptors, which produce a psychoactive impact. So, cannabinol would supply a therapeutic impact with out triggering the “excessive” attributable to THC.
Hashish Presents New Alternatives for Therapeutic
“CBN is just not a managed substance like THC, the psychotropic compound in hashish, and proof has proven that CBN is protected in animals and people. And since CBN works independently of cannabinoid receptors, CBN may additionally work in all kinds of cells with ample therapeutic potential,” says first creator Zhibin Liang, a postdoctoral fellow within the Maher lab.
The findings additionally recommend that cannabinol may shield the mind towards different neurodegenerative ailments corresponding to Parkinson’s. In addition they noticed glutathione depletion with Parkinson’s, however cannabinol would preserve mitochondria intact.
“Mitochondrial dysfunction is implicated in adjustments in numerous tissues, not simply within the mind and growing older, so the truth that this compound is ready to keep mitochondrial perform suggests it may have extra advantages past the context of Alzheimer’s illness,” Maher stated.

Maher notes that the examine reveals the need for additional analysis on how cannabinol interacts with the mind. Additionally, they need to examine different much less widespread cannabinoids to check their therapeutic potential. In whole, the hashish plant incorporates between 80 to 100 completely different cannabinoids.
The following step of the analysis will contain replicating the leads to a preclinical mouse trial. Hopefully, the research will result in higher remedies for Alzheimer’s and Parkinson’s sooner or later.

Different Advantages of Cannabinol
Whereas little analysis exists concerning the therapeutic results of cannabinol, some research reveal its advantages. Listed here are just some methods hashish can heal the mind and physique:
- May present ache aid. A 2019 rat examine found that CBD and CBN relieved myofascial ache in rats. Nevertheless, a mix of CBN and CBD lowered ache greater than both compound by itself. The researchers discovered that each compounds may assist handle ache from fibromyalgia and temporomandibular issues.
- Might delay symptom onset of amyotrophic lateral sclerosis (ALS). A 2005 examine on rats found that CBN delayed illness onset by greater than two weeks and didn’t have an effect on the rats’ survival. Since ALS is a neurodegenerative illness, CBN seemingly works in the identical areas of the mind that trigger Alzheimer’s and Parkinson’s.
- It may have anti-inflammatory advantages. One other 2016 rat examine revealed that cannabinol may decrease arthritis-related irritation. Nevertheless, no research have been carried out in people to date.
Cannabinol may have a number of therapeutic functions and presumably stop neurodegenerative ailments from creating. This examine additionally proves that nature is the perfect drugs, so we should always use our efforts to guard it.
Closing Ideas on Examine Displaying that Hashish Protects In opposition to Alzheimer’s
Many research have confirmed the protecting results of hashish, however most have targeted on the compounds THC and CBD. Since practically 100 completely different cannabinoids exist in hashish, it’s important to be taught all we are able to about them. Researchers from The Salk Institute in California have lately studied the compound CBN and located that it may stop neurodegenerative ailments.
Whereas extra analysis is required, the preliminary findings present that cannabinol protects nerve cells from oxidative harm, which causes eventual cell demise. Since oxidative harm is a vital contributor to Alzheimer’s and different neurodegenerative ailments, it’s clear that cannabinol will play a job in future remedies.
