Hemp or CBD Oil: What it is and What it is Not

Have you been following the hemp/CBD oil conversation? “Medical marijuana”, “vaping”, “low (or high) THC levels”... these words, phrases and abbreviations are getting thrown around a lot these days. Are you one of the many befuddled by the whole conversation? 

I definitely was. Even in light of the supposed health benefits that are being publicized, does the concept of taking a street drug for medical purposes set you on high alert (no pun intended)?

If it doesn't, maybe it should… but that's beside the point. *wink*

Are you as ready as I am for some clarification?

Some History

Let’s start by talking specifically about the hemp plant. Hemp, although from the same family, is a separate plant from marijuana (more on that later) and it is this specific plant that is referred to in ancient records. Used for centuries (as far back as 2737 BC) as a pain-reliever and treatment for multiple conditions including seizures, stomach disorders, migraines, inflammation, depression, lack of appetite and asthma – hemp has been included in medical practice by almost every culture around the world. We have sources from India, China, England, the Middle East and the doctors who founded the healthcare of early America, all singing the praise of this versatile leafy plant (which, by the way, can also be used for other purposes - construction, food, and even to make plastics and automobiles). Ancient medical revolutionists such as Pliny the Elder (circa 77 AD), Disocorides (70 AD) and Galen (200 AD) all included hemp in their practices, recording outstanding results. And much more recently, four pharmacopoeias written in the 19th century, “The New England Dispensatory” and “Edinburgh New Dispensatory” among them, list hemp as a treatment for pain, skin inflammation, gout, neuralgia and convulsions. W. B. O’Shaughnessy, an Irish surgeon and professor at the Medical College of Calcutta in the 1800s, is credited with establishing its use in the western world and performing several studies to test its efficacy. Research in the same vein was continued until the end of the 1800's by Dr. J. R. Reynolds.[1] 

The historical proof of its value notwithstanding, hemp slowly disappeared from U.S. pharmacies and home use in the 1900's as opiates came onto the scene as a new option for pain-relief. And finally, in 1970, it was unintentionally lumped into the set of drugs outlawed by the Controlled Substances Act. How did this happen? Well, as we mentioned earlier, hemp - like marijuana - is from the cannabis family. This caused some confusion!

Hemp vs. Marijuana: Two Plants with Similar Chemical Structure but Very Distinct Effects

What was apparently not clarified prior to the government's banning of hemp is the scientific fact that hemp and marijuana, although in the same plant family, are set apart by their physical appearance, growth requirements, and most importantly, active chemical constituents and uses.

All plants from the cannabis family contain phytocannabinoids – chemical compounds that make up somewhere around 40% of the plants’ extracts. Of the 113 identified cannabinoids, those that are most prevalent and which exert the most action upon the human body are CBD (cannabidiol) and THC (tetrahydrocannabinol). These chemicals act upon the endocannabanoid system - a complex system recent medical research has confirmed plays an essential role in preserving homeostasis, promoting proper immune system function, and regulating inflammatory processes in the body[2] – by interacting with specific membrane-bound receptors, termed CB1 and CB2. Research suggests there may be other receptors as well[3]. While THC binds primarily to receptor sites in the brain (causing psychoactive effects), CBD has a more widespread effect, particularly acting on the immune system, intestines and stomach among other areas, and is actually antipsychotic.[4]

As far as other characteristics go, marijuana (Cannabis indica) plants grow best indoors and are short, densely branched and have wide leaves. Their high THC content (5-35%) - which THC, bear in mind, is the chemical that affects the brain - is responsible for the buzz or "high" (and accompanying detrimental effects) experienced by marijuana users. Although THC is beneficial in the sense that it confers relaxation, appetite-stimulation and creativity-enhancement to the user, it is also responsible for sedation, disorientation, dizziness, tachycardia (increased heart rate), anxiety, paranoia and greater likelihood of developing psychological disorders and suicidal tendencies[5].

Hemp (Cannabis sativa) plants, on the other hand, are typically grown outdoors, and in appearance are tall (reaching up to 20 feet), loosely branched and have narrow leaves. They generally require very little care, growing well without cultivation. In multiple studies conducted over the past two decades, CBD has specifically been shown to help regulate stomach acids, protect the endothelial lining of the gut from damage or repair damage already done, provide substantial pain relief due to its ability to reduce inflammation, and ease nausea and vomiting[1] (among many other possible uses that will be listed later). And here's the real kicker (drum roll, please): 

Sativa (hemp) plants, contrary to their sister strain of indica (marijuana), have a HIGH concentration of CBD and a very LOW amount of THC (less than 0.3%).  In fact, CBD has an antagonistic effect on THC[1]. This renders THC’s psychoactive effects, in hemp, pretty much nil. 

This means that while marijuana does indeed have some medicinal effects, it also confers to the user psychoactive consequences that may be unwanted - while hemp, alternatively, has a much greater medicinal effect and basically none of the potentially dangerous effects on the brain. This also explains why the very popular CBD products so many are using these days are made from CBD extracted from hemp plants.

They are plants from the same family, with a similar chemical makeup, but very distinct effects.

Hemp as Modern Medicine

Although temporarily forgotten, hemp is becoming popular again. The research is ongoing, but the last two decades of investigation has suggested a growing number of possible applications including using CBD for managing multiple sclerosis[6], anxiety[7], autoimmune and inflammatory diseases such as RA[8], cancer[9], chronic pain, liver injury [7], fibromyalgia, PTSD, Crohn's disease and similar digestive disorders[10]and treatment-resistant epileptic seizures[11]. In fact, the FDA has already approved a new pharmaceutical made of hemp, called Sativex, for the management of multiple sclerosis[12], and other similar hemp-derived drugs are in the works.

A quick search on PubMed, one of the most respected online medical study databases, lists 26,696 results in response to the key word "hemp" and 11,034 for "CBD". What is evident is that research on CBD is happening, and this in itself is a very good indication that herbal practitioners throughout history and today’s scientific minds are agreed: hemp is a gift to mankind.

As well-stated by the Baltimore Post Examiner, "there is no doubt as to the excitement over the possibilities."[13]
