Cannabidiol—CBD—is a cannabis compound that has significant medical benefits, but does not make people feel “stoned” and can actually counteract the psychoactivity of THC. The fact that CBD-rich cannabis is non-psychoactive or less psychoactive than THC-dominant strains makes it an appealing option for patients looking for relief from inflammation, pain, anxiety, psychosis, seizures, spasms, and other conditions without disconcerting feelings of lethargy or dysphoria.
Scientific and clinical research—much of it sponsored by the US government—underscores CBD’s potential as a treatment for a wide range of conditions, including arthritis, diabetes, alcoholism, MS, chronic pain, schizophrenia, PTSD, depression, antibiotic-resistant infections, epilepsy, and other neurological disorders. CBD has demonstrable neuroprotective and neurogenic effects, and its anti-cancer properties are currently being investigated at several academic research centers in the United States and elsewhere.
Project CBD responds to inquiries from all over the world. Almost everyone wants to know where to get CBD-rich products and how to use them for maximum benefit. After decades in which only high-THC cannabis was available in North America and beyond, CBD-rich strains and products are now available to medical users.
“CBD-rich” versus “CBD dominant:” By “CBD-rich,” we mean a cannabis strain or product that has equal amounts of CBD and THC, or more CBD than THC (usually at least 4 percent CBD by dry weight.). By “CBD-dominant,” we mean strains or products that are CBD-rich but have very little THC content.

A Beginner’s Guide to Cannabidiol & Cannabis Therapeutics
In 2009, a handful of CBD-rich cannabis strains were discovered serendipitously in Northern California, America’s cannabis breadbasket, where certified patients could access medical marijuana legally. Thus began a great laboratory experiment in democracy involving CBD-rich cannabis therapeutics. The advent of whole plant CBD-rich oil as a grassroots therapeutic option has changed the national conversation about cannabis. It’s no longer a question of whether medical marijuana works – today the key question is how to use cannabis for maximum therapeutic benefit. But most health professionals have little experience in this area. So Project CBD has created a CBD User’s Manual for patients that addresses key questions about cannabidiol and cannabis therapeutics.
What is CBD?
Cannabidiol or CBD is a non-intoxicating component of the cannabis plant with enormous therapeutic potential. Although CBD doesn’t make people feel high like THC does, it’s causing quite a buzz among scientists, health professionals, and medical marijuana patients who are using CBD-rich products to treat a wide range of conditions – chronic pain, cancer, Crohn’s, diabetes, rheumatoid arthritis, PTSD, cardiovascular disease, anxiety, antibiotic-resistant infections, multiple sclerosis, schizophrenia, and more. Academic research centers in the United States and elsewhere are currently studying the effects of CBD on these and other ailments. Scientists refer to CBD as a “promiscuous” compound because it confers therapeutic benefits in many different ways while tapping into how we function physiologically and biologically on a deep level. Extensive preclinical research and some clinical studies have shown that CBD has strong anti-oxidant, anti-inflammatory, anticonvulsant, anti-depressant, anti-psychotic, anti-tumoral, and neuroprotective qualities. Cannabidiol can change gene expression and remove beta amyloid plaque, the hallmark of Alzheimer’s, from brain cells.
Which is better CBD or THC? Cannabidiol and THC (The High Causer) are the power couple of cannabis therapeutics; they work best together. CBD and THC interact synergistically to potentiate each other’s curative qualities. CBD enhances THC’s painkilling and anticancer properties, while lessening THC’s psychoactivity. CBD can also mitigate adverse effects caused by too much THC, such as anxiety and rapid heartbeat. When both compounds are present in sufficient amounts in the same cannabis strain or product, CBD will lower the ceiling on the THC high while prolonging its duration. (“Relaxing but not intoxicating” is how one patient described CBD-rich cannabis.) CBD broadens the range of conditions treatable with cannabis, such as liver, cardiovascular and metabolic disorders, which may be less responsive to THC-dominant remedies. CBD and THC both stimulate neurogenesis, the creation of new brain cells, in adult mammals.
What’s the best way to take CBD? The most appropriate delivery system for CBD-rich cannabis is one that provides an optimal dose for a desired duration with few unwanted side effects. CBD-rich cannabis flower varietals for smoking or vaping are available in many medical marijuana dispensaries, but most CBD patients prefer non-inhalable products made with cannabis oil concentrates. Although banned by federal law, measurable doses of potent CBD-rich cannabis remedies are available in many non-smokable forms and can be utilized in various ways. The time of onset and duration of effect vary depending on the method of administration. CBD-rich cannabis oil products can be taken sublingually, orally (as edibles, lozenges, beverages, tinctures, and gel caps), or applied topically. Concentrated cannabis oil extracts can also be heated and inhaled with a vape pen. Inhalation is good for treating acute symptoms that require immediate attention; the effects can be felt within a minute or two and typically last for a couple of hours. The effects of orally administered CBD-rich cannabis oil can last for four hours or more, but the onset of effects is much slower (30-90 minutes) than inhalation.

What is the right CBD:THC ratio for me? Cannabis therapeutics is personalized medicine. There is no single ratio or strain or product that’s right for everyone. Optimize your therapeutic use of cannabis by finding the proper combination of CBD and THC that works best for you. A person’s sensitivity to THC is a key factor in determining the appropriate ratio and dosage of CBD-rich medicine. Many people enjoy the cannabis high and can consume reasonable amounts of any cannabis product without feeling too high or dysphoric. Others find THC unpleasant. CBD can lessen or neutralize the intoxicating effects of THC. So a greater ratio of CBD-to- THC means less of a high. In some states with medical marijuana laws, cannabis oil concentrates and other products with varying ratios of CBD:THC are available so users can adjust or minimize psychoactive effects to suit their needs and sensitivities. Those who don’t like THC have the option of healing without the high by using a CBD-rich remedy with only a small amount of THC. But a low THC remedy, while not intoxicating, is not always the most effective treatment option. In essence, the goal is to administer consistent, measurable doses of a CBD-rich remedy that includes as much THC as a person is comfortable with.
Are specific CBD:THC ratios better for different conditions? Some patterns are beginning to emerge. For anxiety, depression, spasms, psychosis, and seizure disorders, many people report they do well starting with a small dose of a CBD-rich remedy with little THC. For cancer, autism, and many other diseases, some say they benefit more from a balanced ratio of CBD and THC. Extensive clinical trials conducted outside the United States have shown that a 1:1 CBD:THC ratio can be effective for neuropathic pain. Some people use cannabis products with different CBD:THC ratios at different times of the day (more CBD for sunlight hours, more THC at night). Almost any cannabis strain or product theoretically could benefit a wide range of autoimmune and inflammatory disorders because THC and other cannabis components activate the CB2 cannabinoid receptor, which regulates immune function. Note: The CBD:THC ratio in not an indication of how much CBD or THC is present in a given cannabis product or strain.
What is the optimal dosage of CBD? An effective dosage can range from as little as a few milligrams of CBD-enriched cannabis oil to a gram or more. Begin with a small dose of high CBD/low THC oil, especially if you have little or no experience with cannabis. Take a few small doses over the course of the day rather than one big dose. Use the same dose and ratio for several days. Observe the effects and if necessary adjust the ratio or amount. Don’t overdo it. Cannabis compounds have biphasic properties, which means that low and high doses of the same substance can produce opposite effects. Small doses of cannabis tend to stimulate; large doses sedate. Too much THC, while not lethal, can amplify anxiety and mood disorders. CBD has no known adverse side effects, but an excessive amount of CBD could be less effective therapeutically than a moderate dose. “Less is more” is often the case with respect to cannabis therapy.

What should one look for when choosing a CBD-rich product? Look for products with clear labels showing the quantity and ratio of CBD and THC per dose, a manufacturing date, and a batch number (for quality control). Select products with quality ingredients: No corn syrup, transfats, GMOs, artificial additives, thinning agents or preservatives. CBD-rich products should be lab tested for consistency and verified as being free of mold, bacteria, pesticides, solvent residues, and other contaminants. Best to avoid products extracted with toxic solvents like BHO, propane, hexane or other hydrocarbons. Opt for products that utilize safer extraction methods such as supercritical CO2 or food-grade ethanol.

If CBD is so good, won’t pure CBD be even better? Single-molecule CBD will inevitably become a federally approved Big Pharma medicine. Products infused with a crystalline CBD isolate, derived and extensively refined from industrial hemp, are already being marketed by unregulated internet storefronts. But single-molecule CBD is less effective therapeutically than whole plant CBD-rich oil extract. Scientific studies have established that synthetic, single-molecule CBD has a very narrow therapeutic window and requires precise, high doses for efficacy, whereas lower dose, whole-plant, CBD-rich treatment regimens are already showing efficacy for many conditions among patients in medical marijuana states. Whether synthesized in a Big Pharma lab or derived from industrial hemp, single-molecule CBD lacks critical secondary cannabinoids and other medicinal compounds found in high-resin cannabis strains. These compounds interact with CBD and THC to enhance their therapeutic benefits. Scientists call this the “entourage effect.” Numerous cannabis compounds have medicinal attributes, but the therapeutic impact of whole plant cannabis is greater than the sum of its parts.

Is there a difference between CBD derived from hemp and CBD derived from marijuana? If you live in a state where medical marijuana is legal and available, look for CBD products made from high-resin cannabis (rather than low resin industrial hemp) that are sold in medical marijuana dispensaries. Hemp-derived CBD-infused products of varying quality are also available via dozens of internet storefronts. Compared to whole plant CBD-rich cannabis, industrial hemp is typically low in cannabinoid content. A huge amount of hemp is required to extract a small amount of CBD, thereby raising the risk of contaminants because hemp, a bioaccumulator, draws toxins from the soil. That’s a great feature for restoring a poisoned ecosystem, but it’s not recommended for extracting medicinal oil. Heavily refined CBD paste or terpene-free CBD powder is poor starter material for formulating CBD-rich oil products. The FDA has tested dozens of so-called CBD “hemp oil” products and found that in many cases these products contained little or no CBD. CBD-infused nutraceuticals have not been approved by the FDA as food supplements; nor are these products legal in all 50 U.S. states. By and large, however, interstate CBD commerce is tolerated by federal authorities.
Is it safe to inhale hemp CBD oil fumes from a vape pen? Many cannabis- and hemp-derived CBD vape oil products include a thinning agent, which dilutes the oil that is heated and inhaled by vape pen users. Beware of vape pen oil that contains propylene glycol. When overheated, this chemical additive produces formaldehyde, a carcinogen, as a byproduct, according to a 2015 report in the New England Journal of Medicine. Why do so many vape oil products contain this thinning agent? It’s because of the dubious quality of the extracted material from which these unregulated cannabis oil products are made.

Does CBD have any adverse side effects? What about drug interactions? CBD is a very safe substance, but patients taking other medications should check with their doctor about drug interactions, which are more likely when consuming high doses of single-molecule CBD products. At sufficient dosages, CBD will temporarily deactivate cytochrome P450 enzymes, thereby altering how we metabolize a wide range of compounds, including THC. Cytochrome P450 enzymes metabolize more than 60 percent of Big Pharma meds. CBD is a more potent inhibitor of cytochrome P450 than the grapefruit compound Bergapten, so ask your doctor if grapefruit interacts with your medication. If grapefruit does, then CBD probably does, too. Patients on a CBD-rich treatment regimen should monitor changes in blood levels of prescription medications and, if need be, adjust dosage.
Will big pharmaceutical companies control the CBD market when cannabis is legalized for adult use? Only if we let them. Cannabis is a medicinal herb and it should be regulated as an herb, not as a pharmaceutical or a street drug.

Heal Your Headache – Migraine Diets Support Group
I highly recommend picking up a copy of “Heal Your Headache”. It was a complete game changer for me, and the principles and diet program outlined by Dr. Buchholz are what turned my life around. Cannabis is incredibly helpful, but if you can prevent/reduce the migraines themselves rather than just addressing the pain, you may be able to live your life again. There is an amazing group you can join full of people supporting each other through this type of diet. The admins Eileen and Danielle are in our MigraineBuds discussion group too!

Is CBD Legal?
In Canada, CBD is legal for medical use.
In the United States however, the issue is far more complicated. Most CBD companies will tell you that CBD from Hemp is legal in all 50 states, as long as the THC content is below .3%. It makes sense. CBD is harmless, THC is the boogey monster, right? Well those CBD companies are also selling a product, so they are less likely to inform you that there is some legal grey area here. Just because the government hasn’t begun shutting them down doesn’t make them legal. And that doesn’t make any of it less ridiculous or fair. Still confused? So was I.
- I wrote a letter to Americans for Safe Access in hopes they could clarify my confusion. Click here to read my letter and their response.
- On Projectcbd.org, they address CBD’s legality as being one of the most common misconceptions.https://www.projectcbd.org/article/cbd-misconceptionsPurveyors of imported, CBD-infused hemp oil claim it’s legal to market their wares anywhere in the United States as long as the oil contains less than 0.3 percent THC. Actually, it’s not so simple. Federal law prohibits U.S. farmers from growing hemp as a commercial crop, but the sale of imported, low-THC, industrial hemp products is permitted in the United States as long as these products are derived from the seed or stalk of the plant, not from the leaves and flowers. Here’s the catch: Cannabidiol can’t be pressed or extracted from hempseed. CBD can be extracted from the flower, leaves, and, only to a very minor extent, from the stalk of the hemp plant. Hemp oil start-ups lack credibility when they say their CBD comes from hempseed and stalk. Congress may soon vote to exempt industrial hemp and CBD from the definition of marijuana under the Controlled Substances Act. Such legislation would not be necessary if CBD derived from foreign-grown hemp was already legal throughout the United States.
That blows! Does that mean I can never buy/try it?
Yes, that certainly does blow. It blows hard. But there are at least 16 states with a “CBD Only” law that allows patients and caregivers to possess non-psychoactive CBD Products. There are also many states that have now fully legalized marijuana! Check out this link to learn more about legality specific to your state:
CBD is legal in the following countries, according to http://www.endocafoundation.org :
Argentina, Austria, Belgium, Belize, Brazil, Bulgaria, Canada, Chile, China, Colombia, Costa Rica, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Georgia, Germany, Greece, Guam, Guatemala, Hong Kong, Hungary, Iceland, India, Ireland Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands Antilles, Northern Ireland Norway, Paraguay, Peru, Poland, Portugal, Puerto Rico, Romania, Russia, Slovenia, South Africa, Sweden, Switzerland, U.S. Virgin Islands, Uruguay
