Cannabicyclol (CBL)

Cannabinoids are the compounds in the cannabis plant that provide health benefits. You can find at least 85 of them in marijuana, one of them being cannabicyclol (CBL).

CBL’s Properties

Cannabicyclol is usually shortened to the acronym CBL. Some folks also call it cannabipinol and shorten the name to CBP. Regardless of what you call it, little research has been conducted on it so far. Most existing studies examine the CBL molecule’s biosynthesis and structure — scientists first discovered the compound in 1964.

When the cannabinoid cannabichromene (CBC) decays from light exposure, it turns into CBL. While both CBC and CBL occur in much smaller amounts than cannabinoids like THC or CBD, a plant usually has more CBC than CBL. As cannabis ages, it begins to have less THC and CBD and more CBC and CBL. A multidisciplinary research team from China found cannabis from the BCE era that had CBC and CBL as its two most prominent cannabinoids. So, even after sitting out for thousands of years, marijuana is still effective!

What Makes CBL Different From Other Cannabinoids?

Cannabicyclol has the molecular formula C21H30O2. Many other cannabinoids — like CBD and THC, the two most studied cannabinoids — have similar formulas. What makes CBL unique is the arrangement of its atoms and the fact that it has no double bonds. The double bonds in the psychoactive cannabinoid THC give the compound its cerebral effects. Since CBL doesn’t have double bonds, it can’t cause psychoactive effects.

You will find CBL in cannabis in much, much smaller amounts than you will other cannabinoids. Since it appears in such small quantities, scientists have had a tough time studying it properly.

The Medical Benefits of CBL

The insignificant amounts that CBL appear in cannabis in have severely limited researchers’ ability to study it, so we don’t know too much about its medical benefits. When it was investigated alongside other cannabinoids for its potential to reduce prostaglandin production, it had little to no impact. Prostaglandins control muscle contractions, so it doesn’t seem to have the ability to help with that symptom.

Health Issues Treatable With CBL

Due to the lack of scientific literature on CBL, we don’t really know what health issues it could relieve. So far, results indicate it has little to no effect. We also know that CBL doesn’t cause any harmful effects. Keep up with our blog updates to learn of any breakthroughs related to CBL as soon as they happen.
