Cannabis has long been of interest to scientists, especially its two main components, Cannabidiol (CBD) and Tetrahydrocannabinol (THC) . Although these substances work very differently, recent research reveals their subtle interactions. The latest findings suggest that CBD may help reduce the side effects of THC, such as addiction and memory loss, while enhancing its beneficial properties.
CBD is one of more than 200 naturally occurring cannabinoids found in the cannabis plant. Unlike THC, it does not cause a psychoactive effect, meaning it does not make you feel high. Its popularity skyrocketed after the 2018 Farm Bill legalized industrial hemp in the United States.
THC, on the other hand, is the main psychoactive component of cannabis. It actively interacts with cannabinoid receptors in the brain, causing a euphoric state, but can also cause unwanted effects, including anxiety, memory loss, and addiction. With long-term use of high doses of THC, the likelihood of mental disorders such as anxiety and depression increases.
Recent research published in ACS Neuroscience suggests that CBD may modulate the receptors that THC interacts with, which could help mitigate the negative effects of THC use, such as anxiety and short-term memory problems.
Scientists have found that CBD acts as a kind of "switch" for receptor activity, allowing the effects of THC to be regulated. For example, if THC activates a receptor and causes euphoria, CBD can partially block or weaken this action, helping to avoid an excessive psychoactive effect. This effect may be useful for those who use cannabis for medical purposes but do not want to experience a pronounced change in consciousness.
This discovery has important implications for medicine. If we can precisely regulate the interaction of CBD and THC, we could develop safer cannabis-based drugs, for example, to treat chronic pain, multiple sclerosis, epilepsy, and even some mental disorders.
Current research is exploring the possibility of developing drugs in which the ratio of CBD to THC is strictly controlled. This could allow patients to receive the maximum benefit from cannabinoid therapy while minimizing the risk of unwanted effects.
Scientists are also considering the possibility of creating synthetic CBD, which could modulate the work of receptors even more effectively and reduce the unwanted effects of THC. This could open a new page in the pharmacology of cannabinoids. In the future, it will be possible to develop drugs containing artificially synthesized molecules that more specifically affect certain receptors in the body.
One of the most promising areas of research is the use of CBD to reduce opioid addiction. Some evidence suggests that CBD may reduce cravings for drugs and help patients suffering from addiction .
However, it is important to consider that CBD itself can also interact with various receptors in the body. Researchers are studying how exactly it affects opioid receptors and whether this can cause unwanted effects when taken simultaneously with, for example, morphine. In addition, research is ongoing into the effects of CBD on other systems in the body, including the effect on cortisol levels and the stress response.
Since August 16, 2024, the use of medical cannabis has been officially legalized in Ukraine . The law aims to expand patient access to treatment for chronic diseases, including cancer and post-traumatic stress disorder (PTSD). According to estimates by the Ministry of Health of Ukraine, about 6 million citizens could benefit from medical cannabis. However, it can only be purchased with a doctor's prescription, and recreational use remains prohibited.
Ukrainian lawmakers are also considering adding PTSD to the list of medical conditions for which cannabis treatment is permitted. This is especially important for war veterans suffering from the after-effects of combat. In the coming years, training programs for doctors are planned to ensure proper prescription and monitoring of medical cannabis use.
This applies exclusively to medical cannabis with controlled THC and CBD content. Isolated forms of CBD are also completely legal and available, which are not subject to strict restrictions and can be used in a number of therapeutic cases.
The interaction of CBD and THC is the key to safer and more effective use of cannabis in medicine. The ability to control their effects will help create new drugs that can change the lives of millions of people. Understanding the mechanisms of these substances will help integrate them into official medicine and create safe drugs based on them.
Before using any cannabinoid products, it is important to consult with a medical professional to determine their safety and appropriateness in each individual case. It is also important to monitor legislative changes in the field of medical cannabinoid use, as regulations and restrictions may vary by region.
