Dr. Adán de Salas Quiroga PhD is a neuroscientist and cannabis researcher with a background within the biology of the endocannabinoid system and the potential of medicinal cannabis. He did his PhD at Complutense College of Madrid the place he spent 10 years researching the therapeutic software of cannabinoids on most cancers, neurodegenerative issues and mind growth.
Dr. de Salas is especially serious about creating frameworks for top of the range training and assist for the medical group in a broad vary of features associated to the sector of medicinal cannabis. He sees the gradual uptake of cannabis remedy by docs as a disservice to the 1000’s of sufferers the plant may also help. He’s at present devoted to sharing his information in a manner that contributes to the event of a protected and reliable medical cannabis group.
QUESTION: You labored as a cannabis researcher for a few years. How would describe what you do at present, and the way it can profit the trade?
I very a lot loved my work as a researcher however after a while I noticed how divorced our work was from the appliance of the remedy. In actual fact, I discovered working in a laboratory to be fairly isolating. I wished to get out into the sector and be concerned within the software of the therapies. Right this moment, I largely work in a consultancy function for medical cannabis firms advising on medical translation, which implies the creation of considerable medical trials to show efficacy. However really, the aim is similar: to advance the medical analysis and software of medicinal cannabis.
What we now have proper now are polar extremes, insofar as individuals are both tremendous pro-cannabis or completely towards it. And for my part, those that say that cannabis is a cure-all and can be utilized for all the things are simply as unhealthy because the individuals who criticize it. There’s no query that cannabis is probably an incredible device however we even have to think about what’s reasonable, and what are the contexts during which the usage of cannabis is advisable. I see cannabis being a catalyst for a change within the medical paradigm, pushing open the door to customized medication, which is the alternative of the standard allopathic medical observe.
QUESTION: Proper now, docs are gradual to prescribe cannabis to sufferers. What mannequin do you see in place sooner or later that helps docs overcome this reluctance to work with cannabis?
What’s wanted now are details, info and training. Already in international locations just like the U.S., Mexico, Uruguay and Argentina, there are licensed medical cannabis packages obtainable to the medical group. One thing related is required in Europe. I wish to see the creation of a program devoted to docs, a program that’s shorter than a Masters and kinds a part of their persevering with medical training. That manner, it might be included in a credit score system that’s acknowledged by an official medical establishment.
QUESTION: With regards to cannabis, how can docs navigate the road between advocating for remedy and the sufferers who particularly request medical cannabis remedy?
I imagine this can be a blended determination between the physician and the affected person. I see this with different medication. For instance, there are some medication that solely a health care provider can prescribe, so the affected person goes to the physician that may prescribe that drug. There’s all the time the chance that folks will take a prescription drug towards the recommendation of their physician, and even the opposite manner round. In my view, cannabis needs to be one other device for each sufferers and docs. To have change, each communities will need to have sufficient training concerning the potential of it and in addition the best way to make use of it. The factor about cannabis is that there isn’t any single dose that’s going to work for everybody, not even for a similar indication. The dose is the decided by the affected person. Plus, medical cannabis comes with its personal set of negative effects, and we even have to have the ability to take these into consideration.

Tis the season to get good and stoned. Responsibly.
QUESTION: Let’s get medical. What’s the endocannabinoid system (ECS) and what operate does it serve within the physique?
The very first thing to know is that the ECS is current, in various features, in all animals except for bugs. It’s the principle molecular goal of phytocannabinoids, the cannabinoids discovered within the cannabis plant. However most necessary, it’s a molecular system that helps to translate info from the outer a part of the cell to the cell. Principally, it’s a communication system however the kind of info that it will probably transmit is kind of completely different relying on the kind of cell it’s speaking with, for instance an endocrine cell versus a neuron. And it’ll have a special impact on the cell relying on which cell it’s speaking with. So, it’s very dynamic relying on the mobile context.
The entire system is advanced however we now have recognized 4 teams of molecules, the primary of which incorporates endocannabinoids akin to anandamide and 2-arachidonyl glycerol (2-AG). Subsequent are the cannabinoid receptors CB1 and CB2, however the expression of those receptors modifications very a lot relying on the mobile context, the tissue and the physiopathological state. A sure kind of tissue might categorical a small quantity of cannabinoid receptor however in a physiopathological state might categorical a really completely different quantity of receptors. Once more, it’s very dynamic. Subsequent are the metabolic enzymes, that are mandatory for the biosynthesis and degradation of the endocannabinoids, and play a significant function within the general system.
As I discussed, the ECS is a system that interprets info, and to ensure that this info to transmit a coherent message, it must be very tightly managed in time and house. That is achieved by means of tight management of biosynthesis and degradation of the endocannabinoids. That is the job of the enzymes, and their motion ensures the consequences of endocannabinoids are localized in a selected space. There are completely different enzymes for every group of endocannabinoids. After which the fourth group of molecules is known as allosteric modulators, that are lipid compounds that up and down-regulate the signaling of cannabinoid receptors. All of those 4 components working collectively are what we name the endocannabinoid system.
It controls an in depth checklist of features due to the presence of some ingredient of the ECS in each organ tissue within the physique. Although its features are various, we will say usually its job is to keep up homeostasis, the steadiness of the physiological system in concord with the interior and exterior atmosphere, which is continually altering. Throughout the central nervous system, the principle function of the ECS, particularly, CB1, is as a retrograde neuromodulator to manage homeostasis, which has quite a few results on the remainder of the physique. In the end, the ECS controls many features akin to metabolism and ache, and lots of extra.
QUESTION: What’s the function of Fatty Acid Amide Hydrolase (FAAH) in metabolism of endocannabinoids?
The primary job of this enzyme is the degradation of anandamide with a view to keep homeostasis. As I stated, this can be a communication system, and it really works by transmitting a sign to at least one place however not one other with a view to modify the physiology of a cell, which might trigger it to supply extra of a sure issue, to begin migrating, to supply extra protein or launch cytokines. So, FAAH is conditioning sure physiological mechanisms. For instance, there’s a excessive degree of FAAH within the uterus the place its function is to manage ranges of anandamide with a view to guarantee profitable implantation of an embryo.
QUESTION: Are you able to clarify the metabolism of endocannabinoids and the way it differs from metabolism of THC?
Endocannabinoids are primarily degraded by enzymes, for instance, anandamide is degraded by FAAH and 2-AG is degraded by monoacylglycerol lipase (MAGL). Nevertheless, once we discuss phytocannabinoids, the cannabinoids that come from the cannabis plant akin to THC and CBD, they’re largely metabolized by a bunch of enzymes known as cytochrome P450, an enormous household of enzymes discovered within the liver. These enzymes are liable for metabolizing and degrading all medication and toxins that folks take. Basically, endocannabinoids are fat which can be metabolized regionally, whereas phytocannabinoids are terpenophenols.
QUESTION: Are you able to clarify why the medical functions of THC and CBD differ?
Whereas they share some traits, they act by means of completely different mechanisms relying on their molecular targets. The pharmacology of those compounds is advanced however, for instance within the case of THC, we will say that a lot of the motion of this compound will depend on its binding to cannabinoid receptors. THC is known as a partial agonist of the cannabinoid receptor, which implies it will probably bind to the orthosteric pocket of the receptor, in impact becoming into it the identical manner a key suits into the keyhole of a lock.
Nevertheless, CBD can not do that as a result of its molecular construction has no affinity to this “keyhole,” and due to this fact can not bind to the receptor the identical manner THC does. However CBD is ready to enter the “keyhole” of different receptors akin to PPAR-gamma and TPRVI, and it has an oblique impact on the ECS. Some research counsel that CBD can be capable of inhibit FAAH, which signifies that CBD might up-regulate the ECS. So, THC and CBD have completely different pathways. For example, the psychotropic results are attributable to the activation of CB1 receptors within the mind. As CBD is just not capable of activate these receptors, it’s not psychotropic. Nevertheless it does work on cells within the immune system, which is why it’s anti-inflammatory.
QUESTION: You probably did your analysis on most cancers, neurodegenerative issues and mind growth. How can cannabis remedy assist these circumstances?
Given the significance of the endocannabinoid system for the event of the mind, it’s doable {that a} dysfunction within the ECS might be concerned within the growth of sure pathologies akin to epilepsy and autism. It’s believed that these pathologies are established throughout embryonic growth although they manifest in later years for each kids and adults. If we will establish the underlying dysfunction within the embryonic stage, it might be very fascinating for future remedy programs. However this can be a very advanced course of, and plenty of work must be carried out earlier than any functions are doable.
We all know much more about neurodegenerative issues, and I imagine there’s a particular software for controlling the development of the illness and treating circumstances akin to Huntington’s illness, which is what we research in our lab. When it comes to most cancers, until now we all know that cannabinoids are useful in palliative care, serving to sufferers handle urge for food and ache. Nevertheless, we now have researched the antitumoral properties of cannabinoids, and that is one thing that reveals nice promise for the long run. What’s wanted now could be medical research on the antitumoral motion of cannabinoids on various kinds of most cancers.
