What is CBD

What is CBD?



Cannabidiol (CBD) is one of many cannabinoid molecules produced by Cannabis, second only to THC in abundance. These plant-derived cannabinoids, or phytocannabinoids, are characterized by their ability to act on the cannabinoid receptors that are part of our endocannabinoid system.
While THC is the principal psychoactive component of Cannabis and has certain medical uses, CBD stands out because it is both non-psychoactive and displays a broad range of potential medical applications. 
Perhaps the most remarkable thing about CBD is the sheer number and variety of its potential therapeutic applications. It is important to recognize that each application may be supported by different levels of evidence. These range from ongoing clinical trials evaluating its efficacy in the treatment of human disorders, to animal studies investigating its behavioral and physiological effects.
"The fact that CBD-rich cannabis is non-psychoactive or less psychoactive than THC-dominant strains makes it an appealing option for patients looking for relief from inflammation, pain, anxiety, psychosis, seizures, spasms, and other conditions without disconcerting feelings of lethargy or dysphoria."

What is CBD and How does the Body Use it?

The brain contains large numbers of highly specialized cells called neurons. Each neuron connects to many others through structures called synapses. These are sites where one neuron communicates to another by releasing chemical messengers known as neurotransmitters.
All neurons contain multiple neurotransmitter receptors, allowing them to respond to some neurotransmitters but not others.



Brain receptors are not only sensitive to neurotransmitters produced naturally within the brain, like dopamine or serotonin, but also chemical messengers produced outside the body, such as plant cannabinoids like THC or CBD. So when you ingest an edible or inhale some vapor, you’re allowing compounds originally produced by a plant to enter your body, travel through your bloodstream, and enter your brain. Once they arrive, these plant-derived compounds can influence brain activity by interacting with receptors on neurons. But they don’t interact with all neurons, just the ones that have the appropriate receptors.



Scientific and clinical research—much of it sponsored by the US government—underscores CBD’s potential as a treatment for a wide range of conditions, including arthritis, diabetes, alcoholism, MS, chronic pain, schizophrenia, PTSD, depression, antibiotic-resistant infections, epilepsy, and other neurological disorders. CBD has demonstrable neuroprotective and neurogenic effects, and its anti-cancer properties are currently being investigated at several academic research centers in the United States and elsewhere. Further evidence suggests that CBD is safe even at high doses. Some researchers say low does are good for the day to help keep you awake, and higher doses are better at night to help you sleep. Although this cannabis medicine may affect patients differently.



What are Cannabinoid Receptors?

Although it is a cannabinoid, CBD does not directly interact with the two classical cannabinoid receptors (CB1 and CB2).  Instead, it affects signaling through CB1 and CB2 receptors indirectly. In addition to its indirect influence on the CB1 and CB2 receptors, CBD can increase levels of the body’s own naturally-produced cannabinoids (known as endocannabinoids) by inhibiting the enzymes that break them down.

Even more intriguing: CBD also influences many non-cannabinoid receptor systems in the brain, interacting with receptors sensitive to a variety of drugs and neurotransmitters. These include opioid receptors, known for their role in pain regulation. CBD can also interact with dopamine receptors, which play a crucial role in regulating many aspects of behavior and cognition, including motivation and reward-seeking behavior.

This raises the intriguing possibility that CBD’s ability to influence either the opioid or dopamine receptors may underlie its ability to dampen drug cravings and withdrawal symptoms, effects directly relevant to the treatment of addiction.

At this point more research on CBD’s interactions with the opioid and dopamine receptor systems is still needed.
CBD’s therapeutic potential with respect to addiction also extends to the serotonin system. Animal studies have demonstrated that CBD directly activates multiple serotonin receptors in the brain. These interactions have been implicated in its ability to reduce drug-seeking behavior. CBD’s influence on the serotonin system may also account in part for its anti-anxiety properties, which have been robustly demonstrated across both human and animal studies.



CBD and Epilepsy


CBD is famous for the promise it holds for treating treatment-resistant forms of childhood epilepsy. A number of clinical trials, testing the efficacy of CBD in human epilepsy patients, are currently underway. But there is also evidence, mainly from animal studies and in vitro experiments, that CBD may have neuroprotective, anti-inflammatory and analgesic (pain-relieving) properties, and potential therapeutic value in the treatment of motivational disorders like depression, anxiety, and addiction.
What’s the biological basis for this wide range of potential medical uses? A key part of the answer lies in CBD’s promiscuous pharmacology—its ability to influence a wide range of receptor systems in the brain and body, including not only cannabinoid receptors but a host of others.
