On this page, we talk about cannabinoids and more specifically what is CBD.
Products that are high in CBD but not THC do not cause intoxication at all. Instead of intoxication, CBD relaxes the body and reduces e.g. pain and anxiety (1).
The potency of cannabis is based on the cannabinoids and terpenes it contains. Cannabinoids can be classified into external cannabinoids, ie phytocannabinoids, internal cannabinoids, ie endocannabinoids, and synthetic laboratory-produced cannabinoids. More than 100 cannabinoids and more than 200 terpenes have been found in hemp. The best-known active ingredients in hemp are delta-9-tetrahydrocannabinol (THC), cannabidiol (CBD), and cannabinol (CBN) (1).
The medicinal as well as intoxicating effects of hemp were discovered thousands of years ago. There is a heated debate today on the legality of hemp and cannabis. Previously, the cultivation of both oil and fiber hemp was completely banned in Finland for decades, and hemp-related research was stopped elsewhere in the world.
Legal cannabis products usually report CBD and THC levels as a percentage. If there is little or no CBD, then THC can be thought of as a measure of its strength in much the same way as the percentage of alcohol in beverages. CBD works almost in the opposite direction and partially reverses the intoxicating effects of THC (1).
WHAT IS CBD?
CBD, or cannabidiol, has become known for its medicinal effects. CBD is currently used to treat various diseases and e.g. recovery from sports and recovery from various stressful situations such as concussion (2, 4).
The cannabidiol present in raw hemp is still mostly in its natural acid form, cannabidiol acid (CBD-A), which is converted to CBD by time and heat (3). CBD products are often made from industrial useful hemp that does not contain narcotic amounts of THC.
CBD mitigates the psychoactive effects of THC in hemp. Products that are high in CBD but not THC do not cause intoxication at all. Instead of intoxication, CBD relaxes the body and reduces e.g. pain and anxiety (1).
“CBD is classified as an antipsychotic and neuroprotective cannabinoid, meaning it relieves anxiety and calms. Studies have shown that CBD is beneficial in the treatment of muscle spasticity, MS, epilepsy and insomnia. ” (Vanha-Majamaa, 2018, p.23)
It is precisely CBD that is used by people with epilepsy or MS because it has been shown to reduce obsessive-compulsive disorder, muscle stiffness, and seizures (1).
CBD has been found to relieve pain, reduce inflammation, be a more effective antioxidant than vitamin C or E, and have anti-nausea, antipsychotic, and antiepileptic effects through 5-HT1A, GPR55, GPR18, TRPV1, and other TRP receptors, among others. , (5, 6 and 7).
WHAT ARE THE EFFECTS OF CBD?
CBD has been found to slow the natural breakdown of anandamide and thus increase the amount of endocannabinoids in brain synapses. This increase in endocannabinoids may be a significant factor in the neuroprotective and other health effects of CBD (8).
In addition, CBD has been studied to increase the amount of the neurotransmitter adenosine, which regulates the activity of adenosine receptors. A1A and A2A receptors play an important role in the cardiovascular system, regulating myocardial oxygen uptake and blood flow in the coronary artery. These receptors also have broad anti-inflammatory effects in the body (9).
CBD increases the aminobutyric acid binding capacity of the natural agonist of the GABA-A receptor. Aminobutyric acid is one of the most important neurotransmitters in mammals. This increased butyric acid binding has sedative and anxiolytic effects (10). CBD also has a similar negative effect on the CB1 receptor, which reduces the psychoactive effects of THC (11).
CBD is associated with the TRPV1 receptor, which is known to affect pain, inflammation, and body temperature (12).
According to some studies, CBD affects the so-called as an agonist that blocks or inactivates the GPR55 receptor. The GPR55 receptor is found especially in the cerebellum. It is involved in the regulation of blood pressure, bone density, etc. physiological processes. When it is overactive, osteoporosis occurs, which can potentially be treated with CBD. It has also been found to have antiproliferative effects, i.e., to reduce the proliferation of cancer cells. The GPR55 receptor causes the proliferation of cancer cells and is manifested in several types of cancer (13).
CBD also potentially creates cancer-reducing effects by activating PPA receptors that are expressed in the nuclei of cells. Studies have shown that PPA receptor activation has anti-proliferative effects as well as the ability to regress on cancer (14, 15). In addition, its activation has been found to degrade amyloid-beta plaque, which is a major cause of Alzheimer’s. Therefore, the PPA receptor agonist CBD may be useful in Alzheimer’s patients (16). PPA receptors also regulate genes involved in energy homeostasis, lipid uptake, insulin sensitivity, and other metabolic processes. Thus, CBD may also potentially help in the treatment of diabetes (17, 18)
SUMMARY OF BENEFITS OF THE CBD
- reduce pain
- reduces inflammation
- improves appetite
- improves digestion
- improve metabolism
- to help you fall asleep
- enhances the immune system
- balances homeostasis
- prevents the growth of cancer cells
- relieve anxiety
- Protects cells, tissues and organs from oxidation
DOES THE CBD HAVE SIDE EFFECTS?
According to a WHO report, the use of CBD is safe and there is no dependence or risk of abuse. Read the full report on the WHO website.
According to some studies, high levels of CBD may affect the efficacy as well as the absorption of certain drugs. Thus, CBD may have undesirable interactions with certain drugs, so we always recommend that you identify potential risks before use.
CBD works in the body through cannabinoid receptors and is excreted mainly by the liver. The cytochrome p450 enzyme plays a key role in the metabolism of CBD and CBD can increase the activity of these enzymes (19). These CYP enzymes are found especially in the liver, but also everywhere else. CYP enzymes play a key role in drug metabolism. CBD and certain drugs may increase or decrease the effectiveness of the drug in a dangerous way
