Cannabinoid receptors CB1 and CB2 are the definitive and best-known targets of endogenous and plant-derived cannabinoids, but they’re far from the only ones.

Several phytocannabinoids, including cannabidiol (CBD), for example, and the two primary endocannabinoids — anandamide and 2-AG — have been shown to interact with peroxisome proliferator-activated receptors, or PPARs1 (pronounced pee-parrs), which are found on the surface of the cell’s nucleus. This may help to explain how CBD, which has little affinity for either CB1 or CB2, can do so much.

Get to Know the PPARs

PPARs are a group of nuclear receptors that play important roles in regulating metabolism, inflammation, and gene expression. Triggered by hormones, endocannabinoids, and other fatty acid derivatives, and various nutritional compounds,2 PPARs are expressed in different parts of the body:

PPAR-a (PPAR-alpha) is found in the liver, kidney, heart, and skeletal muscle, as well as adipose (fat) tissue and the intestinal tract;PPAR-b (PPAR-delta) is expressed in adipose tissue, skeletal muscle, heart, and liver; andPPAR-y (PPAR-gamma), which comes in two forms, is expressed in almost all tissues of the body including the colon, the cardiovascular system, and immune cells.

The first evidence of an endocannabinoid interacting with PPARs came in 2002, when a research team in Tennessee showed that a metabolite of 2-AG activated PPAR-a.3 Since then many more breakthroughs have been made, and peroxisome proliferator-activated receptors are now viewed as an extension of the classic endocannabinoid system (ECS).

PPARs are now viewed as an extension of the classic endocannabinoid system.

Hemp and cannabis are two varieties of the same plant species, Cannabis sativa. However, they differ in their chemical composition, cultivation, and usage. Hemp is typically grown for industrial use and contains very low levels of THC (tetrahydrocannabinol), the psychoactive compound that produces the "high" associated with cannabis use. In fact, i...

It has long been known that resinous cannabis flower tops are infused with robust therapeutic properties. But there are also pharmacologically active components in other parts of the plant that shouldn’t be ignored when assessing the health benefits of cannabis.

The earliest reference to the therapeutic use of cannabis dates back to 2700 BC in ancient China, “the land of hemp and mulberry.” Cannabis (“Ma”) was subsequently included in the Shennong Ben Cao Jing, humankind’s first pharmacopeia, which had been assembled by Emperor Shen Nung, the legendary father of traditional Chinese medicine, who is credited with introducing the custom of drinking tea. Ma was recommended for more than a hundred ailments, including gout, rheumatism, malaria, constipation, beri-beri, and absent-mindedness.

The Shennong Ben Cao Jing called Ma one of the “Supreme Elixirs of Immortality.” It was said to confer longevity and good health. If consumed over a long period of time, Ma could “enable one to communicate with the spirit light and make the body light. It mainly supplements the center and boosts the qi [chi]. Protracted taking may make one fat, strong, and never senile.”1

When consumed in excess, however, “it may make one behold ghosts and frenetically run about.”

Seeds of Health

In traditional Chinese medicine, protein-rich cannabis seeds figured prominently both as a food source and a remedy — apparently more so than resinous cannabis flower tops. The seeds don’t contain CBD, THC, or any other cannabinoids. But modern science confirms that cannabis seeds are an excellent source of omega 3 fatty acids, which are indispensable biochemical building blocks for a healthy endocannabinoid system.

Plastic Pollution in California

Inspired by Project CBD’s exposé, “Bag the Tags” (June 29, 2022), California state senator Ben Allen has introduced a bill to end the onerous requirement to apply a plastic tag to every cannabis plant grown by licensed cultivators, as is currently mandated under the state’s track-and-trace program. Sponsored by CannaCraft, Inc., a major cannabis producer (and longtime friend of Project CBD), and supported by several organizations including the National Product Stewardship Council and the California Cannabis Industry Association, Senate Bill 622 seeks to mitigate unnecessary labor and operational costs for cannabis cultivators, while eliminating the creation of millions of pounds of plastic waste that can’t be recycled.

As Project CBD reported last year: “With over 2,000 acres licensed to grow cannabis, California cannabis farmers put between 30 and 55 million plants in the ground every year. The tags are the definition of ‘single use’ – they can only be used on one plant and never re-used during subsequent growing seasons. That’s a lot of plastic tags for an industry with green pretensions.”

The ostensible purpose of imposing the tag rule was to monitor cannabis grown in California to make sure that it would not end up in the illicit market within or outside the state. But the factsheet summarizing SB 622 emphasizes that “individual plant tags are completely ineffective in preventing diversion.” Why? Because cannabis can’t be diverted until the plants are harvested! And the tags are removed and discarded after they are pulled from the ground.

The SB 622 factsheet asserts: “In a state that prides itself on championing environmentally sensitive initiatives designed to stop climate change and improve the environment, it is antithetical and irresponsible to continue to mandate plastic plant tagging, which does nothing to prevent diversion.”

In the first part of this series, we reviewed recent research into the role of the CB2 cannabinoid receptor in cancer proliferation. This week we turn our attention to another fascinating aspect of CB2 function: its impact on psychiatric and mood disorders despite not being concentrated in the central nervous system (CNS).

After all, the CNS is the domain of its sibling, the CB1 cannabinoid receptor — the primary target of THC and the mediator of cannabis’ intoxicating effects. CB2, by contrast, is more prominently expressed in the peripheral nervous system, where it regulates inflammation, pain, and neuroprotection. CB2 is found to a much lesser extent in the brain, where it modulates dopamine signaling, neuroinflammation, and neurogenesis.

The CB2 receptor was of particular interest to visionary cannabinoid scientist Raphael Mechoulam. In the year prior to his recent passing at age 92, Mechoulam was still actively involved in research investigating CB2 in a variety of disease models. Here we look at a couple of his final papers on CB2 and mental health, as well as two related reviews published in the same timeframe.

CB2 & Schizophrenia

First comes a paper on CB2’s role in schizophrenia, a condition related to psychosis whose symptoms include hallucinations, delusions, disorganized thinking, social withdrawal, decreased emotional expression, and apathy. Coauthored by Brazilian scientists affiliated with the University of São Paulo, it appeared in the journal Progress in Neuro-Psychopharmacology & Biological Psychiatry1 in July 2022.

“The CB2 receptor modulates dopaminergic neurotransmission, which is abnormally enhanced in schizophrenia patients,” the authors explain. That much is clear. Given this, they wanted to know, how might “HU-910,” a synthetic research compound that selectively activates the CB2 receptor, affect behavior in a rodent model of the disease?

CBD, or cannabidiol, has been shown to have potential benefits for relieving nausea and vomiting in some people. Nausea can be caused by a variety of factors, including chemotherapy, motion sickness, anxiety, and certain medical conditions. Research has shown that CBD can interact with the body's endocannabinoid system, which plays a role in regula...

The cannabinoid receptor CB1, primary target of THC in the brain, is known for mediating the cannabis high. And its counterpart CB2, mainly expressed in immune cells throughout the body, is understood to play an important role in inflammatory processes. These abstractions are accurate as far as they go, but as with anything related to the endocannabinoid system, reality is far more complex.

Project CBD’s recent article on the passing of Raphael Mechoulam noted that the esteemed scientist believed CB2 should be a focus of future cannabinoid science. The CB2 receptor interacts with THC, CBD, endocannabinoids, and other compounds in a multitude of organs including skin and bone.

Recent research — including papers co-authored by Mechoulam well into his 80s — has confirmed that aberrant CB2 signaling is implicated in a raft of autoimmune, neurodegenerative, metabolic, and psychiatric disorders. CB2 is also an increasingly hot topic in cancer research.

In this two-part series, Project CBD will explore some of the latest studies and what they reveal about what we know — and still don’t know — about this ubiquitous, somewhat mysterious cell receptor.

This week: cancer. Next week: cognitive and mood disorders, including some of Mechoulam’s final work before his death in March at the age of 92.
