Opioid receptors are the key targets of pharmaceutical pain killers and drugs of abuse such as morphine, heroin, and fentanyl. 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.
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. Professor Roger Pertwee, an English pharmacologist renowned for his research on cannabinoids, spoke with Leafly about this aspect of CBD biology.
Given that these possibilities come mainly from animal studies, more research will be needed before we can think seriously about human applications. But that complexity may be the key to its promise as a therapeutic agent. Motivational disorders like addiction and anxiety are themselves highly complex; they arise from incompletely understood causes that span multiple receptor systems and neural networks in the brain.
An incredibly detailed and authoritative article on CBD. Looking forward to reading more articles for CBD Week.
CBD Week is a great idea and I hope you explore other topics in a similar fashion. No Hoosier should have to leave their home, their family, their friends to obtain a life changing medication. Try to stick with taking a dose, then waiting to be genuinely mindful of the effect before taking more — this will prevent you from raising your tolerance and will allow you to figure out what the right dose for you is.
For example, homemade edibles often have an uneven distribution, due to the handmade nature of home baking. Some dispensaries even in states where cannabis is only medically legal mostly are aimed at recreational users.
At medical places, employees will be knowledgeable about dosages, the menu will be very clear about dosages and usages, there will be a wide range of CBD products, and some will even offer additional medical or educational services such as workshops or visits with cannabis-friendly herbalists.
I feel much more peaceful, able to sleep more soundly and be among people without anxiety. Focus is more centered in the present moment. This is the story of our 5 year old Charlotte Figi. Charlotte suffered from Dravet Syndrome, a severe form of epilepsy found in children.
From the time she was 2 she was having over seizures a week which drastically affected her ability to learn, speak or even walk. She was unable to keep up with her twin sister. She was catatonic and nothing the doctors could do for her helped. Some of them almost killing her. After exhausting all other treatments, her we turned to the internet to see what alternative treatments may be available. So we made the decision to give cannabis oil to Charlotte and from the first dose we noticed results.
Jaqie Angel Warrior is my two-year old who has suffered from multiple types of seizures since she was five months old. Dozens of medications, including Depakote and klonopin, failed to control the thousands of seizures and caused terrible side effects. Most children need some significant quantity of THC to see transformational results. Get to him via his number I suffer from general anxiety, so it really helps me settle down and just focus on the design problems I have in front of me.
I am 48 years young and I have epileptic seizures. I will do everything within my power to educate people about CBD. Recommend this firm to anyone looking at Cannabis for help!!
For anybody interested in vaping CBD. I ordered a vape pen and tried it for the first time. CDB has helped me keep my stress levels down and has helped me tremendously with dealing with my anxiety. Best thing is that CBD is legal in all 50 States and I can vape my great tasting odorless pen anywhere! You should check out http: CBD has really helped me reduce my anxiety and difficulty to focus while studying. I used to fidget quite a bit when i was sitting for a long time although i never had learning disabilities of any sort.
It has been demonstrated that THC exposure leads to the significant increase in the 4T1 carcinoma growth and metastasis due to the inhibition of the specific antitumor immune response Observed effects were mediated by CB2 receptors It is possible that tumors originating from tissues of low CB receptors expression would be significantly less sensitive to cannabinoids anticancer action and, eventually, due to THC immunosuppressive properties, such tumors may find a favorable environment for growth and development.
It is also possible that anticancer properties of cannabinoids may be compensated by their immunosuppressive action, finally leading to promotion of the tumor growth. Chronic inflammation has been associated with the development of neoplasia; therefore, reducing inflammation may, to some extent, contribute to the prevention of carcinogenesis.
Viability of noncancerous cells seems to remain unchanged or sometimes even elevated by cannabinoids 34 , 35 , 36 , 39 , On the other hand, cannabinoids can trigger apoptotic cell death in some types of nontransformed cells, especially those of high proliferative properties such as endothelial cells The cellular response to cannabinoids relies on different mechanisms in cancerous and noncancerous cells. It has been demonstrated in vitro that cannabinoids can exhibit a stimulatory activity in nanomolar concentration and an inhibitory activity in micromolar concentration biphasic response , which significantly exceeds concentrations usually detected in blood of marijuana smokers Concentration of THC used in described experiment corresponded to its serum concentration obtained by smoking or oral administration of THC Besides the above described proapoptotic effect in cancer cells, cannabinoids exhibit some other important and potentially valuable properties.
It has been demonstrated that they can inhibit angiogenesis by blocking an activation of the vascular endothelial growth factor VEGF pathway. Cannabinoids have also been shown to reduce spontaneous and induced metastases in animal models and to inhibit an invasiveness of cancer cells in vitro breast, lung, cervical cancer, and glioma 86 , 87 , 88 , 89 , These effects are partially connected with a modulation of the activity of extracellular proteases and their inhibitors 86 , The pharmacological inhibition of ceramide biosynthesis and the expression of p8 protein lead to the prevention of the mentioned effects The studies conducted to date indicate that antiangiogenic and antimetastatic characteristics of CB receptor agonists, similar to their antiproliferative effects, rely on the stimulation of ceramide biosynthesis and a modulation of pathways involving p8 protein.
Cannabinoids that are not agonists of CB receptors CBD , have also been shown to exhibit such properties. Increased levels of FAAH substrates e. Data collected to date regarding anticancer effects of cannabinoids are almost completely limited to preclinical studies conducted on cell lines and animal models. The first experiment that was conducted on human subjects was a pilot clinical study on nine terminal patients with recurrent glioblastoma who were resistant to the standard therapy Patients received THC intratumorally.
This way of administration was safe and patients did not exhibit any overt psychoactive effects. In some patients the tumor growth rate decreased. Changes observed upon THC administration in two patients can be connected with anticancer effect of THC according to previous preclinical studies decreased cell proliferation, occurrence of apoptosis Despite these interesting observations, it is not possible to draw significant conclusions from the study on a group of nine.
This shows a need for further clinical trials, which could help to assess the dosage and the potential interaction of cannabinoids with other substances. These studies are currently ongoing or have ended recently, but the results have not been published to date. Cannabis plants produce a substantial amount of cannabinoids and other secondary metabolites. It has been demonstrated that extracts of Cannabis exhibit stronger effects on the subjects with spasticity than pure THC Some cannabinoids have been demonstrated to attenuate psychoactive effects of THC or smoked marijuana 13 , Pure cannabinoids are more convenient for study and to a subsequent standardization as a medical preparation, but still Cannabis extracts with specified amounts of cannabinoids seem to be valuable aim for further studies, also as potential anticancer agents.
An interesting idea is a combination of cannabinoids with conventional anticancer drugs, which can exhibit synergistic potential. The promising results from studies on animal models of glioblastoma treated with THC and temozolomide have led to, mentioned above, clinical trial of this chemotherapeutic agent and Sativex 94 , Similar observations from the study on pancreatic adenocarcinoma showed that gemcitabine administered with cannabinoids synergistically inhibited cancer cell growth To date, Cannabis or its preparations have found an application in a palliative medicine due to its analgesic and antiemetic effects, an attenuation of the side effects of chemotherapy or a capacity to treat spasticity in multiple sclerosis.
We are still initial stages of incorporating Cannabis products in the clinical care. There is still a lack of profound safety and efficacy clinical trials and it is very difficult or even impossible to assess the potential benefits and risk of using cannabinoids in many cases. Many aspects wait for an elucidation: The most common way of using recreational marijuana is smoking, which is unsuitable way of an administration from a medical point of view.
Another important issue is the lack of easy accessible biomarkers showing the responsiveness of patients to a cannabinoid treatment. Moreover, antitumor effects of cannabinoids have to overcome their known immunosuppressive effects which can be potentially protumorigenic.
The interactions between cannabinoids and classical cytotoxic agents have to be precisely defined. These observations lead us to the conclusion, that further profound studies are doubtlessly needed to verify the idea of introducing cannabinoids into the cancer treatment.

Abstract To date, cannabinoids have been allowed in the palliative medicine due to their analgesic and antiemetic effects, but increasing number of preclinical studies indicates their anticancer properties. Introduction Nowadays, we observe an increasing public and scientific interest in the medical applications of Cannabis plants. Endocannabinoid system and cancer Despite numerous studies conducted during the last decade, there are still inconsistent data regarding the exact role of cannabinoid system in cancer development.
Open in a separate window. Cannabinoids and the immune system The mechanism of the immunomodulatory effects of cannabinoids is still not fully elucidated. Selectivity and stimulation of viability Viability of noncancerous cells seems to remain unchanged or sometimes even elevated by cannabinoids 34 , 35 , 36 , 39 , Inhibition of angiogenesis and metastasis Besides the above described proapoptotic effect in cancer cells, cannabinoids exhibit some other important and potentially valuable properties.
