Rationale for Genetically Guided Cannabis Therapy

Rationale for Genetically Guided Cannabis Therapy

By Janna Champagne, BSN, RN

I was first introduced to the topic of epigenetics in 2008 at a business conference in Florida, and as a medical professional I was immediately intrigued. Epigenetics is defined as the environmental impact on gene expression, which explains how genes can be influenced to alter our genetic health expression, like an on/off switch. Depending on exposures, environmental interaction with genes may result in positive or negative impacts on our health. Pretty exciting, since this exemplifies that our overall health is not determined solely based on what our parents contributed. Instead, we as individuals have the ability to positively affect our inherited risk factors for familial diseases (1).

Correctly applied Nutrigenomics (genetically-individualized nutrition) is a positive environmental factor with the potential to improve genetic predisposition to illness, by slowing or halting many contributors to disease (1). This supports what we’ve known for a long time: that given what it needs, the body can balance and heal itself.

Over the years of helping clients optimize their health through nutrigenomics and other alternatives to pharma, I’ve seen some amazing results ie: successful weaning off harmful pharmaceuticals (with physician oversight), and reversals of difficult to treat conditions like cancer and autoimmune. My knowledge of genetics has since crossed over another area of passion: medical cannabis therapy.

Contrary to it’s abhorrent social reputation in the last century, cannabis is proving to be a source of vital nutrients needed to maintain balance in the body, and is therefore a perfect compliment to almost any nutrigenomic regimen. Of course, unique varieties of cannabis exert varying effects on individuals, an issue that may be resolved through a new process allowing for genetic guidance of cannabis therapy.

As you may have already guessed, genetically guided cannabis is very cutting edge, and a bit complex. It’s the overlap of several emerging sciences: the endocannabinoid system, human genetics, cannabis genetics, and botany are all in the mix. If this intrigues you, then you’re definitely a kindred cannabis nerd.

Here’s a little background info: All humans have a master control Endocannabinoid System (ECS), which is so important that it’s widely argued that life would not be possible without its balancing influence (1). The ECS produces endocannabinoids that interact with our body’s receptors, and when activated they promote balance throughout the body systems. (4)

Since the role of the ECS is homeostasis or balance, and the underlying cause of most chronic illness is some sort of imbalance, it makes sense that endocannabinoid deficiency (lacking what’s needed to maintain homeostasis) is linked to chronic illness (5). Since plant derived phytocannabinoids exactly mimic our internally-made endocannabinoids, cannabis supplementation can help fill the EC deficiency gap, and promote the balance necessary to recover health. (3)

This explains how medical cannabis therapy may benefit those suffering chronic illness, and many report cannabis is more effective than pharmaceuticals sans the dangerous side effects. Cannabis is very safe overall, and since it promotes underlying body balance it’s also potentially curative for many diseases. (3) Very few pharmaceuticals exert a curative effect, making cannabis a far superior intervention for chronic illness.

Endocannabinoid deficiency is especially prevalent in today’s society, thanks to nearly a century of cannabis prohibition. This epidemic is the result human ECS pathway mutations/inability to produce ample endocannabinoids, combined with lacking availability/intake of phytocannabinoids. (5)

Every individual has a unique genetic profile, and mutations may reflect predisposition to ECS deficiency, along with many other contributors to imbalance. The cannabis plant contains many medicinal components, including 140+ phytocannabinoids and 200+ terpenes, thereby providing a broad spectrum of the components needed to fill an individual’s ECS deficiency profile (4).

Assessing an individual’s genetics specific to the Endocannabinoid System (including other system pathways that overlap) can help to guide cannabis therapy, which is proving useful to decrease the “trial and error” phase upon starting cannabis, and also provide more consistently positive health outcomes. There are several pathways assessed to determine which cannabis components might best fit an individual’s needs, and genes considered include those from the following pathways (6):

-Serotonin/Dopamine and GABA/Glutamate -Neurotransmitter pathways (cannabinoid profiling, terpene guidance) 9

-Vitamin d3/gcmaf (ECS receptors affected) 10

-Choline pathways (mutation predispose ECS deficiency) 11

-Immune system pathways (for targeted cannabinoid therapy) 12

-AKT1/Schizophrenia predisposition-only known contraindication to THC (13)

-Methylation pathways (addressing mutations mitigates risk factors) 7

and many more…

 

The process of genetic screening is especially important in pediatric applications of cannabis therapy, because methylation pathway mutations predispose neurodevelopmental risks with child/adolescent use of cannabis (7). Methylation mutations are linked to chronic illness, by contributing to harmful systemic inflammation, and dysfunction in both the immune system and detoxification (8). The main reason most seek cannabis therapy for a minor child is chronic illness, making this is a common consideration for children who may benefit from cannabis therapy.

TO BE VERY CLEAR: This doesn’t mean that children and adolescents (even with methylation mutations) shouldn’t use medical cannabis when it’s indicated. Instead this supports that methylation should be optimized with targeted supplementation (nutrigenomics) to mitigate this risk factor.

Genetics are important, but it’s equally imperative to work with a medical professional that understands the basis of an individual’s condition(s), plus other unique cannabis considerations such as medication interactions, etiology of symptoms, and lifespan risk factors. Mitigating as many contributing factors as possible, balancing risk vs benefit, and assessing client goals as a holistic process reinforces optimal medical outcomes. Luckily there are knowledgeable practitioners available to assess genetic cannabis risk factors, and optimize health further through nutrigenomics.

In addition to screening genetics to improve cannabis therapy, full genome assessment and applied nutrigenomics may help address other pathway mutations implicated in chronic illness. My favorite analogy to describe the potential of combining nutrigenomics and cannabis therapy is a sink that’s overflowing with imbalances, thereby causing chronic illness symptoms. Starting cannabis therapy helps the body start balancing, and can be likened to taking the plug out of the drain in this overflowing sink scenario. Applied nutrigenomics can slow or turn off the running faucet. This is a powerful duo for chronic illness indeed.

My hope is to spread knowledge about this very pertinent issue, so that patients and medical professionals alike are aware of the power of using human genetics to guide cannabis therapy. I truly believe this approach represents the future of medical cannabis, and offers a viable option for comprehensive healing of the widespread chronic illness found in our society today.
