I spent 3 years working full-time for PlusCBD before I launched my consulting business so I know from the inside about their commitment to making quality CBD products. But that’s not the most special thing about them. What they do better than any other company in the industry is create a wide range of products.
Nobody else has this much…
The Reserve Collection! Oils, capsules & gummies containing 2.5 mg of THC per serving (I’m constantly being asked how people in non-medical can get THC-rich products & this is always what I recommend to them. Especially because it’s an easy-to-use standard serving size that’s just the right amount for people new to THC)
Excellent pet products in a range of flavors
3 very special formulations with other ingredients:
Sleep gummies: Includes 3 mg of melatonin + extract of lemon balm & magnolia bark (two old plants for inducing sleep)
Calm gummies: Includes 5-HTP (the serotonin precursor) & L-theanine (from tea)
Relief capsules [I can’t find a link to just this item – only the wellness blend bundle]: Includes PEA + CBDA (see the Living Glossary below for why I think these are the ingredients of the future for immune health & gut health)
That’s why I recommend PlusCBD to so many of the clients I consult with: they offer an array of products like no other.

In patients with severe mental health issues, the frequency of their cannabis use was significantly linked to more violent behavior
Is There a Dose-Response Relationship Between Cannabis Use and Violence? A Longitudinal Study in Individuals with Severe Mental Disorders
Nobody wants to hear this, but like most entheogenic drugs, cannabis brings out what's already there. In people predisposed to violence or who want to use it for violence, cannabis enhances that feeling. We see this in rat studies from the 50s, in the use by the Sikhs & other people groups in warfare & in all the kids during the Reefer Madness campaign who smoked a joint before a fight because they were told it would give them berserker abilities.

CBD & CBN have different effects on the membranes of cells
Cannabidiol and cannabinol have distinct effects on membrane structure
This speaks to the old debate in the cannabinoid science world of the ‘80s. Everyone wondered whether cannabis caused its effects by distinct cannabinoid receptors or whether the plant’s cannabinoids altered the entire structure of the cellular membranes & that's why they caused such a wide array of effects.
With the discovery of the cannabinoid receptors in the early 90s, Team Receptor thought they had won. But as is usually the case in science, when the question is either/or, the answer is yes/and.
Now, we learn more every year about how the very presence of cannabinoids alters the structure of the membrane, hence leading to a wide array of downstream effects.

An evergreen note on reading restricted paper:
First stop for seeing if there’s a free version of a paper, use the Google Scholar Chrome extension (Mac version), Google Scholar itself or try ResearchGate.
3 other helpful browser extensions are: Unpaywall, Open Access Button & PaperPanda
For the infamous backdoor, use Sci-Hub – the pirated papers repository (Chrome extension here). This works better for older paper than the stuff that just came out.
For Twitter users, send a Tweet of the paper’s title with the hashtag #icanhazpdf. It works because people are beautiful(ish).
Finally, email the author. They’re almost always happy to oblige because, thanks to the predatory academic publishing system, they don’t make a dollar off of their papers.

The Living Glossary of Cannabinoid Terms
This is a running glossary of the basic cannabinoid terms. It will also function as the legend for the ‘neural ocean’ metaphor that I’m using in my graphic novel series on the endocannabinoid system based on Moby-Dick. You can watch a lecture laying out the full idea here - but the basics are that we treat the human brain like the ocean: deep, mysterious & chockablock with fish, molecules & feedback systems that we don’t understand.
Endocannabinoids are whales. Phytocannabinoids are elephants (because what is an elephant but a whale of the land?) and neurons are complex underwater cities where hundreds of fish interact.
The cannabinoids found inside all mammals & almost every other form of life besides insects
The Endocannabinoids System (ECS)
One of the most widespread signaling systems in the human body & brain - but only first discovered in the early ‘90s. Unlike most of the classical neurotransmitters, endocannabinoid are lipids, or fats. This makes them slippery, hard to study & a supremely sensitive signaling system because of the ability of cells to detect minute changes in lipid levels & act accordingly. Intimately connected to the immune system, the neuronal system & the hormonal system, as one old scientist said to me in his cups, “If you told me that the endocannabinoid system is where the body meets the soul, I’d believe you.”
Anandamide (AEA) [Our Great White Whale]
The first endocannabinoid neurotransmitter ever discovered. Widespread in the human brain & produced ‘on-demand’ when needed. Appears quickly, broken down quickly. Often called the neurotransmitter of balance.
[in our neural ocean metaphor, the sperm whale]
The second endocannabinoid neurotransmitter discovered. Only 2-AG & AEA have been well studied (thousands of research papers)
The first endocannabinoid receptor discovered. Mediates the psychoactivity (getting high feeling of THC). Most importantly, it’s the most widespread receptor of its class in the human brain.
[the bar in the membrane wall of the neuronal city where endocannabinoid whales meet with messenger fish to pass on their messages into the interior of the cellular city]
The second endocannabinoid receptor discovered. Found in almost every organ of the body & closely connected to our immune system. The CB2 occurs at low levels in the brain where it responds to neural insults.
[a gay bar in the membrane wall of the neuronal city]
FAAH (fatty acid amide hydrolase)
The enzyme that breaks down anandamide & a frequent target of drug discovery for modulating the endocannabinoid system. If you inhibit the FAAH enzyme, it does less breaking down of AEA, and your AEA levels rise. More balance.
[the giant squid that slices sperm whales in half]
Diacylglycerol lipase (DAGL or DGL)
The enzyme responsible for producing 2-AG.
MGL (monoacylglycerol lipase - also sometimes abbreviated as MAGL)
The enzyme that breaks down 2-AG. Another frequent target of drug discovery because inhibiting MGL raises 2-AG levels
[a giant octopus that eats blue whales]
An endogenous fatty acid amide whose only reason for not being labeled as a classic endocannabinoid is because it doesn’t bind to the CB1 or CB2 receptor - but it’s a hugely important neurotransmitter found in every cell of the body. A long body of work stretching back to World War 2 has found it to be an amazingly safe & effective drug for a number of things related to the immune system. Available as a dietary supplement, this is one of the best-studied cannabinoids in humans. Highly recommended.
[North Atlantic Right whale of course. Just look at that grin…]
NAAA (N-acylethanolamine acid amidase)
The enzyme for breaking down PEA, with a special function as a messenger for pain & inflammation as well as in the control of obesity.
[a giant Giant Pacific octopus that eats Right whales]
An endocannabinoid related to sleep. They discovered it by keeping cats awake for 3 days & then analyzing their spinal fluid. You can buy it on Amazon. 2 scoops helps you to sleep while 6 scoops is a very pleasant psychoactive experience (Hamilton Morris has called it his favorite way to get high - which is saying something). It’s also worth considering for cancer treatment.
[Humpback whale, because it sings hippies to sleep]
Oleoylethanolamide (unfortunately, also abbreviated as OEA sometimes)
An analog of anandamide, this lipid acts via the peroxisome proliferator-activated receptor alpha (PPAR-α) receptors on the cell’s nucleus. These alter genetic transcription, a powerful method of cellular control. In animal models, oleoylethanolamide causes them to eat less food & drink less alcohol. In roundworms, it causes them to live longer. For the orphaned GPR119 receptor (a receptor that might one day be officially designated as a cannabinoid receptor), it may be the native ligand (the thing that binds to it). It’s already identified as the native ligand for hypoxia-inducible factor 3α (HIF-3α). OEA also interacts with our histamines.
[Pygmy sperm whale. Not well known, a smaller cousin to the sperm whale]
Fatty acid-binding proteins (FABPs)
These transport proteins move fatty lipids such as the endocannabinoids around the body. While still mysterious, they’re thought to move anandamide between membranes as well as transporting it to be broken down by the enzyme FAAH. Several types of FABPs exist in humans. THC & CBD bind to some of them. This may explain why endocannabinoid levels tend to increase after consuming cannabinoids. As the brain ages, the levels of FABPs decrease.
The cannabinoids produced by the cannabis plant.
THC (delta-9-tetrahydrocannabinol or Δ9-THC)
The well-known & well-studied molecule in cannabis that gets you high - and helps in a number of other fascinating ways.
[African elephant. Powerful, unpredictable, beautiful]
The cousin of THC that does not get you high but does a lot of the heavy lifting in why hemp has been such a staple of medicine since before recorded history. In most plants outside those bred for the recreational market, CBD is the most common cannabinoid. It binds to a wide swathe of receptors outside the endocannabinoid system including three serotonin receptors, two opioid receptors, a dopamine receptor as well as glutamate & GABA (the two most widespread neurotransmitters, the basic neuronal signals for excitation & inhibition, respectively)
[Indian elephant. sweet, gentle, you can work with it]
Known as the “mother cannabinoid”, CBG is the chemical precursor to THC, CBD, and the other cannabinoids in the plant. CBG occurs only at low levels in cannabis because it tends to be quickly converted to other cannabinoids. Binding slightly to the CB1 and CB2 receptor, it also inhibits the enzymes that break down anandamide and 2-AG, hence raising the levels of those endocannabinoids. CBG interacts with an adrenaline receptor (α-2 adrenoceptor) & a serotonin receptor (5-HT1A Receptor) as well as modulating the expression of glutamate, GABA, and dopamine via the PPAR receptors on the nucleus, controllers of genetic transcription. CBG is also active at the TRP channels involved in the sensations of temperature, pressure, pH, smell, taste, vision, and pain perception whose dysfunction are linked to neuropathic pain, inflammation, and respiratory disorders.
Surveys show patients reporting help for anxiety, chronic pain, depression, and disturbed sleep. In preclinical trials, it's been studied for eye pressure, gut problems, appetite modulation, blood pressure lowering, bladder control, oral care, muscle spasms, airway inflammation, arthritis, painkilling, and most notably for brain health and neuroinflammation. In adult neural stem cells, CBG increased their viability. The breakdown products of CBG have been shown to reduce inflammation via the brain’s immune cells.
[since it’s the first cannabinoid produced, it must be the wooly mammoth]
The third most common cannabinoid in the plant, it’s not well studied in humans despite a number of intriguing preclinical studies, especially as an anti-inflammatory and for pain. Nonpsychoactive, it interferes with the breakdown of AEA & 2-AG (leading to a rise in their levels) as well as interacting with the vanilloid receptors.
[Sri Lankan elephant. Little, sweet, not as well known as it should be]
CBDV is like CBD with a shortened tail (side chain). Also nonpsychoactive, it tends to occur at low levels in most cannabis cultivars. It’s known to be an anticonvulsant & is suggested for treating autism in humans & in animal models. The cannabinoid pharmaceutical company GW has it in their developmental pipeline as GWP42006.

Δ8-THC (delta-8-tetrahydrocannabinol or THC8)
A more rare cannabinoid in the plant – but one with psychoactive effects. At the moment, the ability to source Δ8-THC from hemp makes it a ‘legal high’ that’s become a hot seller across the US. Of course, the usual legislative & regulatory backlashes are following. It’s been studied as a treatment for glaucoma, eye injuries & the nausea of chemotherapy. Most people describe it as a nice mellow way to get high.
[The forest species of the African elephant – smaller & more elusive]
A terpene that’s also a cannabinoid.
The terpenes of cannabis give the plant its smell. Also found in oregano, black pepper, lavender & hops, beta-caryophyllene has a spicy sweet woody smell. But unique among terpenes, this one also binds to the CB2 receptor, making it a dietary cannabinoid. It shows a potential for treating inflammation, pain, anxiety & seizures. The FDA has designated it to be GRAS (generally regarded as safe) & thus it can be safely used as a food additive.

Nabiximols (ie Sativex®)
A pharmaceutical 1:1 CBD:THC spray produced by GW Pharmaceuticals. One of the first cannabinoid pharmaceuticals on the market, Sativex is an approved treatment for neuropathic pain, spasticity, overactive bladder & the symptoms of multiple sclerosis.
Epidiolex® (in the UK, Epidyolex®)
An isolated CBD formulation approved for treating the severe seizures of Dravet syndrome, Lennox-Gastaut syndrome, or tuberous sclerosis complex. Produced by GW Pharmaceuticals, the doses tend to be incredibly high – hundreds or thousands of milligrams of CBD every day in young children. But even with that, the side effects tend to only be lethargy & stomach upset.
Dronabinol (ie Marinol® and Syndros®)
A synthetic form of THC for the treatment of anorexia in AIDS patients & the nausea of chemotherapy. These tend to not be popular with patients because it’s a horse dose of THC with no modulation by the other molecules in the cannabis plant like CBD.
A synthetic derivative of THC approved for treating the nausea of chemotherapy patients.
