Medicine Meant for You: Integrating Medical Cannabis and Personalized Medicine is the Future of Healthcare

The Promise of Personalized Medicine

The term “personalized medicine” carries the promise of a progressive and holistic approach to healthcare, tailoring treatments to individual patients instead of pathologies. Healthcare providers are now beginning to develop patient tailored treatments based on “clinical, genomic, and environmental information” unique to every individual.1

Where does this information come from and how can we use it to personalize medicine? And how does cannabis fit into the picture?

The answers forecast the future of healthcare and are the basis of exploration in this unique review investigating the integration of medical cannabis with personalized medicine.

“It is more important to know what sort of person has a disease than to know what sort of disease a person has.”
– Hippocrates

P4 Medicine: The Healthcare Revolution

Pioneered by Dr. Leroy Hood, P4 medicine is a revolutionary new perspective on medical practice founded on four pillars: Predictive, Preventive, Personalized & Participatory.2 Rather than seeing a doctor when patients get sick, this new approach advocates for basing treatment heavily on the use of technology, family history and genetics to prevent disease.

By understanding a patient’s family history and genome sequence, better predictions can be made about what conditions to watch out for with a known genetic component (e.g. addiction, depression, heart failure, high blood pressure, etc.)1

As the study of medicine continues, it’s becoming more evident that virtually all diseases have a genetic component in one way or another; the question is, to what degree?3 By asking the right questions, we can start taking the right precautions now to avoid disease later on in life.

Tell Me and I’ll Forget, Show Me and I’ll Understand

The advent of personalized medicine is all about the individual patient, not the disease. This new system can only function optimally when patients are involved in their treatment, too (something that will be discussed later). Thus, the authors thought it would be helpful to the reader if we used an example to help illustrate these new concepts so that readers and future patients can better understand their role in achieving good health.

The Mary Jane Doe Scenario: A Fictional Case Study to Better Understand the Future of Healthcare

Mary Jane Doe is an 18-year old female of average height and weight, and is generally healthy. Mary is going to help us understand what the future of medicine could look like, and how medical cannabis plays a vital role in making the healthcare revolution a reality.

What the Patient Can Expect

rawpixel 577480 unsplashMary Jane is hoping to change the world alongside her free-spirited peers. Before heading off to Colorado State to fulfill her dream of designing the newest hemp-based bio-fuel, she goes to her doctor to get a physical. She follows the usual routine—standing on the scale, sucking on a thermometer and getting strapped to a blood pressure cuff. While this is all fairly straightforward, personalized medicine needs more; it needs to know Mary Jane, the person.

The Family History: Same Questions, Better Reasons for Asking

The physician asks Mary for her family history. She reports that alcoholism, Alzheimer’s disease (AD), and irritable bowel syndrome (IBS), all run in the family. While these questions are normal, it’s how we make better use of the data that makes all the difference.

Genetic Testing: A Simple but Powerful Step

The doctor then orders genetic testing for Mary, which she can easily do inside the office, after her appointment. Mary is given two long Q-tips and swabs the insides of both her cheeks, puts the sample in a sterile bag, seals it and places it in the care of medical staff at her physician’s practice. The staff carefully finishes packaging the sample and will mail it off for testing and await the results.martin adams 701400 unsplash 1

Knowing Where to Look: An Honest & Detailed Family History Helps

The Q-tips contain Mary’s DNA, which can be extracted, sequenced and screened for those particular genetic markers that we know predispose a person to a host of diseases. Using the family history obtained by the physician, the doctor will know what to look for when evaluating the results from Mary’s genetic testing.

Disease, Genetics & P4 Medicine: Putting the Pieces Together

Research into the genetic factors that contribute to the pathogenesis of various diseases has evolved significantly over the years with virtually all diseases being known to have some degree of genetic etiology.3 When patients report a family history of disease, there’s an extremely high likelihood it is at least somewhat genetically rooted, giving doctors an idea of what to look for when screening a patient’s DNA.

What To Look For In Mary’s Genetic Testing Resultssara bakhshi 1080214 unsplash

In Mary’s case, one of the first markers her doctor looked for were those known to encourage the formation of AD by promoting the formation of “plaques” or “tangles” in Mary’s brain.4

Other important markers to look for will be those relating to GI issues such as IBS (reported in Mary’s family history), but also Crohn’s and UC, since IBS is so poorly understood and the utility of genetic testing in developing preventative treatments and testing the potential efficacy of medication is still evolving in the field of gastroenterology.5

Finally, the physician would be wise to investigate whether Miss Jane is genetically predisposed to addiction and overall mental illness (as the two often go hand in hand), as this could affect the type of treatment she could receive, as well as information for Mary to be mindful of.6,7

Once it becomes known that the patient has both a family history of the disease and has the genetic predisposition, preventative approaches can be taken that are specific to preventing disease in the first place. In Mary’s case, genetic markers were identified for all three conditions: AD, IBS/GI issues and Alcoholism/Addiction. How should her physician proceed with this information, and how can cannabis help Mary? This is where things get curiously exciting.

Attacking Alzheimer’s Disease with P4 Medicine

jeremy wong 298986 unsplashThanks to immense sequencing studies and genetic research into Alzheimer’s, almost two dozen distinct and unique genetic biomarkers have been identified as risk factors for both early and late onset AD.8 As such, Mary’s physician has a lot of different genetic markers to look for to assess Mary’s risk for developing AD in her later years.

The neuropathology of AD is characterized by the formation of β-amyloid (Aβ) protein plaques, neuron loss and neurofibrillary tangles comprised mainly of “hyperphosphorylated tau protein”.4 Phenotypically, AD classically presents with chronic and progressive dementia that reaches levels so severe that patients forget the identity of close family members, spouses and eventually, simple tasks such as brushing their own teeth and the meaning of certain words.9

Therefore, preventative treatment should focus on retaining the integrity of Mary’s memory and cognitive functions. There are a host of treatments, including active chemicals in botanicals such as cannabis, that are known to be neuroprotective and neuro-regenerative that will help Mary in this process.

Active Chemicals in Botanicals Target Certain Disease Pathways

There is currently intensive research underway to identify botanicals that have clinically significant physiological effects. For instance, Mary should be advised to include the spice turmeric in her diet, which contains the active ingredient circumin, as it’s known to be clinically effective against AD and even cancer formation.10 The exploration of therapeutic botanicals is also where cannabis finally fits into the picture.

Cannabinoid Therapy & Battling Diseaselexscope 1153352 unsplash

Natural cannabinoids and terpenoids from the cannabis plant have been shown efficacious in treating a wide variety of illnesses and disease. In the instance of Mary, using naboximols (brand name: Sativex; a specific 1:1 whole plant formulation of cannabis by GW Pharma) should help to reduce plaque formation in her brain, reduce oxidative stress, reduce anxiety and even improve dopamine transmission (thus helping reduce Parkinson’s development as well). 11,12

It has even been shown that the terpene’s limonene and alpha-pinene preventm “alpha synuclein fibrillar formation in PD, amyloid fibrillization in AD, and biofilm formation…”, all of which are crucial in the prevention of Alzheimer’s.12–15 Thanks to the implementation of personalized medicine, Mary Jane Doe might be able to avoid the disease that has plagued her family’s genetics.

Preventative Medicine: A Radically Different Approach to Health

This is a completely different approach to medicine than the one that has been in practice for decades. The old dogma—where patients only go to the doctor once they’re already sick—is being abandoned. Preventative medicine is the crux of personalizing healthcare in the future. To really understand the role cannabis plays, we must dig deeper into the science behind personalized medicine and how it works.

Being Proactive in the Treatment of Painrawpixel 974573 unsplash

Part of P4 medicine is the element of participation by all members of a treatment team, including the patient. Having an open and honest dialogue between both the physician and patient is crucial so that important information that might affect the quality of treatment, or even pose a threat to the patient’s health, is not overlooked. For example, patients with a history of drug or alcohol abuse, or those who have a family history of addiction, should be encouraged to share this information honestly with their physicians.

In the future, if a patient with fibromyalgia has a history of alcoholism or drug addiction, along with genetic markers that indicate the same, physicians may be advised to try cannabinoid therapy before the more traditional, yet highly addictive, opioid-based painkillers to treat their pain. Cannabis has been shown to be extremely effective in the treatment of neuropathic pain, as well as a successful adjuvant and alternative to opioid pain medication.16,17

Integrating Cannabis into the Future of Personalized Medicine

The future of personalized medicine has already started to integrate itself into the burgeoning medical cannabis industry. Cannabis Sativa is a rich tapestry of over sixty known phytocannabinoids and over four hundred terpenoids, all working harmoniously in diverse cellular signaling cascades and biological processes across the human body.18,19louis hansel 768769 unsplash

The same genetic screening technology used to sequence the human genome was used to identify the genome of the Cannabis Sativa plant. As we better understand our own biology, as well as that of cannabis, we are able to use science and research to connect the dots and cultivate the best cannabinoid-based therapy regiment for each individual patient.

How Medical Cannabis & P4 Medicine Work Together

Medical cannabis fits into the P4 model in a powerful way. There are virtually limitless combinations of active chemicals in each of the thousands of cannabis strains. Add to that the incredible diversity of switches and levers in the human body that these phyocannabinoinds and terpenoids act upon, adding yet another dimension of complexity and diversity.

Now consider the fact that our body creates its own endogenous cannabinoids, or “endocannabinoids” (2-AG & anandamide being the most well-known), that also modulate the same switches and levers. When cannabis is used and the active chemicals flood into the body, they work in tandem with the bodies intrinsically produced endocannabinoids.

Diversity as a Double-Edged Sword: Complex, Versatile & Confusing

The sophistication of cannabis pharmacology, while being the foundation underscoring its ability to treat such a wide variety of conditions, also makes finding the optimal cannabinoid therapy regiment for a patient very challenging.

Cannabis has co-evolved with humanity over centuries, sharing a bond through the uncommon levels of intra-species diversity exhibited by both humans and C. Sativa. While it is this incredible diversity of the cannabis plant that makes it a powerfully versatile medicine, it also makes choosing the right medicine to reach personal treatment goals a daunting task for patients.

In the blossoming world of medical cannabis, how does one choose the right products to help them achieve the health and happiness they have been seeking for so long?

Everyone Responds to Medical Cannabis Differentlydavid clode 483981 unsplash 1

As medicine evolves, cannabis continues to show promise in the treatment of an expanding list of conditions in a wider variety of patients. Every human being is different, but so are the nuances in their pathophysiology of disease, even if two patients present with the same condition.

Understanding the different biomarkers through genetic and high-throughput testing, as well as the identification of particular genes, proteins and physiological systems in the patient, is crucial to tailoring efficacious cannabinoid therapy. The complexity of cannabinoid pathways, as well as the “individual genetic predispositions” that modulate how different individuals process cannabinoids, ultimately leads to a wide variety of different “body responses” to cannabinoid therapy.20

This can make predicting the effects of a strain or cannabis product difficult, as it cannot simply be extrapolated to represent the entire population. To combat this challenge, researchers are attempting to determine an optimal cannabinoid therapy by looking for the expression of certain genes that we know affect the way cannabis works in the body.

Pharmacogenetics of Cannabisjustin aikin 655509 unsplash

The early days of human genome sequencing were slow and expensive. The Human Genome Project (HGP) began with a $3.5 billion dollar investment and a 15-year expedition before the entire human genome was sequenced.21 Eventually, first-generation sequencing evolved to second-generation sequencing, and today, with the rapid evolution of science and medicine, we are on the cusp of third-generation sequencing, which will offer the opportunity to delineate all of the unique genetic variability in humans and other organisms.21

Polymorphisms are Genetic Signatures of Natural Selection

So how can we translate information and advancements in technology (e.g. genetic testing) to better educate patients and clinicians in selecting the right product from a patient’s dispensary? Patients sometimes express slight genetic variations known as genetic polymorphisms: multiple forms of a single gene that are present in a population.20,22

What may have been an “accidental mutation” at one point in time for an organism may have actually conferred it a survival advantage (e.g. a mutation giving early giraffes a longer neck). Thus, polymorphisms are literally signatures of natural selection—the process caught in action.

nikolay tchaouchev 784485 unsplash

Small, subtle changes in the coding of a gene can have profound impacts in the pathology of disease and the efficacy/toxicity of medications.23 Polymorphisms can cause a partial or complete knockout in the production of crucial proteins needed to metabolize drugs or fight disease.

P450 Genotyping to Determine How an Individual May Respond to Drugs

The genes related to the expression of the P450 family of cytochromes are fundamental to the metabolism of a large variety of drugs (particularly psychiatric and psychotropic drugs) and thus, any variation in their expression will be helpful to know.24

Identifying these polymorphisms is crucial in tailoring the best drug treatment, as well as avoiding any preventable complications. Let’s take a look to see if Mary has any known genetic polymorphisms.

Mary’s P450 Genotyping Reveals P450 CYP2D6 Polymorphism

Mary’s results show she is homozygous recessive for the CYP2D6 cytochrome, meaning she is a “poor-metabolizer” that makes no copies of this protein.22 This doesn’t mean she can’t metabolize the drugs that normally use this pathway at all, she may just need to adjust her dosage. However, it isn’t always so simple, as such a polymorphism can have much greater ramifications for the future treatment of pain, the possibility of addiction, contraindications to certain medications and other important factors yet to consider.

The DXM Dilemma: How Polymorphisms Can Make Therapy Toxicdxm doses

DXM (dextromethorpan), is a popular over-the-counter cough suppressant that is recognized to be in a family of compounds called NMDA-antagonists. The NMDA antagonists Ketamine and PCP act as anesthetics at higher doses; however, both are classically known for their dissociating, hallucinogenic-like qualities at sub-anesthetic doses.25 The recommended therapeutic dosage of DXM is 10-30mg, however, supratherapuetic (very-high) doses of DXM can produce powerful dissociation that is similar to Ketamine and PCP, colloquially referred to as “robo-tripping”.25,23

What’s more intriguing is the metabolism of DXM requires CYP2D6, a cytochrome Mary is unable to produce. This is the perfect example of how genetic testing and personalized medicine could have a powerful and positive impact by way of preventative and strategic medicine.

CYP2D6 Polymorphism Magnifies Psychoactivity of DXM

While the recommended therapeutic dosage of cough medicine containing DXM containing cough medicine is normally far below those what is required to achieve these dissociative effects, there is a small percentage of the population, like Mary, with homozygous deficiency in the gene that encodes the cytochrome CYP2D6 (CYP450 2D6) responsible for metabolizing DXM to into it’s active metabolite, Dextorphan.22

Mary Should Be Wary with Products Containing DXM

Researchers identified a group of patients with this polymorphism who were found to be “poor metabolizers” of DXM who could barely tolerate 3mg/kg doses, while “extensive metabolizers” had no issues with doses between 3-6mg/k.22 However, while poor-metabolizers need far less of the drug to feels its psychoactive effects, patients who were “poor-metabolizers” reported greater sedation and dysphoria (the opposite of “euphoria”; they didn’t like it).22,23kelly sikkema 516850 unsplash

Nonetheless, since DXM is a drug of abuse and so little of it is needed to produce a potentially dissociative or hallucinogenic experience, Mary’s physician would ideally warn her to try other cough suppressants, or to dose DXM-containing products very carefully. While the general consensus from poor metabolizers was that they didn’t like the way DXM made them feel, this doesn’t mean some poor-metabolizers may exploit the fact they don’t need high doses to produce recreational effects.

*The authors strongly advise against the dangerous, harmful and potentially fatal practice of “robo-tripping”. However, since the authors acknowledge humans have free-will, we feel it wise to provide these guidelines to the user that intends to consume DXM in the form of cough medicine:
Some forms of cough-medicine contain other active ingredients besides DXM that are toxic when consumed in the doses necessary to produce dissociation. It is crucial to ensure that the only active chemical listed is dextromethorphan! The medicine should contain NO (1) Guanefesin, (2) Asprin/Acetomenaphin, (3) Antihistamines. High amounts of these chemicals can cause acute liver toxicity,heart-attack, stroke and death.

Polymorphisms Affecting Cannabis Pharmacogenetics

Studies have shown that variations in several genes have direct effects on the “action, metabolism, and the transport of these substances [cannabinoids] in the organism”.28 Just like the polymorphism that makes a small percentage of the population hypersensitive to DXM-containing cough medicine, there are subtle genetic variations that affect how different people metabolize and interact with cannabis.28

Simple genetic testing can identify which gene variants are present in a patient, and that information can be used to determine which cannabinoid and terpenoid profiles cause therapeutic effects compared to those that cause potential side-effects.19,28esteban lopez 346906 unsplash 1

Currently, it is speculated that the underlying mechanism behind the healing properties of cannabis is largely the result of the “entourage effect”.11 The potential combination of different phytocannabinoids and terpenoid ratios, some of which work synergistically with each other, while others oppose each other, fundamentally characterizes the “entourage effect” and is thought to underscore the versatility of cannabinoid therapy.11,12,15

(For a comprehensive exploration of the “entourage effect”, check out this twopart article.)

Chemical Imbalance Can Mean Illness & Disease

It is well established that an imbalance in our bodies’ endogenous (“endo” = inside) neurotransmitters can result in a host of diseases and illnesses. For instance, the neurotransmitter dopamine can be responsible for many diseases ranging from loss of motor control (e.g. Parkinson’s Disease) to mood disorders like major depressive disorder.

Treating such disorders is possible by supplementing the body and brain with exogenous (“exo” = outside) compounds to make up for the deficit; in the case of major depressive disorder due to dopamine imbalance, ketamine infusion therapy has recently shown immense promise in restoring this balance and rapidly treating depression.29

Endocannabinoid Imbalance & Its Implications in Illnessken treloar 385255 unsplash

Likewise, an imbalance in the body’s naturally produced endocannabinoids (2-AG & anandamide, for instance) has been suggested to play a role in various chronic disorders, as the endocannabinoid receptor system is widespread in the human body and brain.30 The official term for this phenomenon is “clinical endocannabinoid deficiency” and is important to address when discussing cannabis as a personalized medical treatment.

Patients like Mary, who have GI disorders like Crohn’s and IBS must consume different cannabinoids and terpenoids than someone attempting to treat anxiety, migraines or fibromyalgia. The future of personalized medicine as it involves cannabis means determining the pathophysiology of an individual’s condition, their genetic makeup, environmental influences and, hopefully in time, assays to determine exactly where shortages, discrepancies and imbalances may lie within the endocannabinoid system to better address these issues in a targeted and efficacious manner.

Medical Cannabis: The Antithesis to “One-Size-Fits-All” Medicine

Cannabinoid medicine is the antithesis of the modern “one-size-fits-all” pharmacopeia of single-molecule drugs used in medicine today. As we identify more biomarkers of disease, we can take further precautions and eventually develop a treatment protocol that is tailored to seamlessly integrate into a person’s lifestyle.

With proper education, genetic testing and consideration of a patient’s environmental and biological factors impacting their biology, new strides can be expected in successfully treating patients with cannabinoid therapy.laura marques 718032 unsplash 1

Daring to Look Ahead: A Chicago Practice Embracing the Future of Healthcare 

While physician’s are beginning to change their perspective on medical cannabis, the ones who are truly embracing it are few and far between. One Chicago practice that is known for its compassion and cutting-edge treatments is going beyond simply giving patients their cards.

Dr. Rahul Khare of Innovative Express Care, perhaps the most notable cannabis friendly medical practice in Chicago, offers cannabis consultations and telemedicine follow-ups to check up on his medical cannabis patients. Genetic testing is also available at the office. From medical cannabis certifications to ketamine infusion therapy, Dr. Khare and his team of medical professionals aren’t waiting for the future, but actively embracing it!

What to Look Forward to in the Medicine of the Future

The field of personalized medicine is quickly emerging and rapidly evolving. Advances in research and technology are opening up possibilities that were never before available in healthcare. Using technology (e.g. wearable fitness trackers), we can upload our vitals straight to our devices and share them with our healthcare team. Gathering biological data and using it to advance treatment is in and of itself a growing field called bioinformatics and is an important part of this healthcare revolution.andres urena 438714 unsplash

Patients will develop entire lifestyles, diets, supplement/nutrient regiments and, when needed, optimized pharmacological interventions that are designed for them, not their condition, leading to a healthier populace and a greater well-being.
