CBD oil is rapidly emerging as one of the most popular natural remedies on the market today. It seems to be literally everywhere, with both alternative and conventional businesses scrambling to cash in on the craze by boldly advertising its health benefits.
I was shocked to see recently that some cafes in my community are advertising CBD on menus as a healthy ingredient in lattes and smoothies! Some “health-oriented” bars are adding it to cocktails.
In some places like New York City, cannabis food trucks sell an assortment of candy and other goodies containing CBD to passersby.
With no age restrictions on its use, some people – even children – are likely consuming CBD on a very frequent basis.
While a growing chorus of voices recommends CBD oil for all manner of ailments with glowing reviews and assurances of its safety, consumers would be wise to think very carefully before jumping on the bandwagon.
This article seeks to pull back the curtain on the CBD story and reveal the very real potential dangers of use by otherwise healthy people so that you can make a truly informed decision for your family.
Please note that I am not disputing the benefits of cannabis in this article. I know it helps a lot of very sick people manage their illness in a comfortable way without the need for pharmaceuticals. What I am presenting is the other side of the story that is usually not discussed – even glossed over in favor of aggressive marketing to otherwise healthy people.
What is CBD Oil?
CBD oil is an alternative remedy for inflammation, pain, seizures and many other conditions. It is gaining widespread popularity over pharmaceutical drugs to treat the same ailments.
Manufacturers make CBD oil by diluting the active ingredient cannabidiol with a carrier fat such as coconut oil. Depending on what carrier oil is used (i.e., saturated fats or vegetable oils), the remedy then appeals to a wider variety of people. In other words, CBD fans can find an oil that fits their particular food philosophy on fats.
Cannabidiol
You might be surprised to learn that cannabidiol is one of over a hundred compounds known as cannabinoids. The buds, flowers, leaves, and stalks (not seeds) of the hemp plant contain them. Other common names for this plant are marijuana or cannabis.
Tetrahydrocannabinol, better known as THC, is another well-known cannabinoid in hemp plant matter. It is best known for its mind-altering effects, which pot smokers experience firsthand. (1)
Fans of CBD oil claim that cannabidiol is safe because it has zero inherent psychoactive properties like THC. However, this is disputable, if not downright false, in light of research on both animals and humans. More on this later.
Hash (Cannabis) Oil vs CBD Oil vs Hemp Seed Oil
It is important to understand the key differences between the three primary oils derived from the hemp or marijuana plant. These characteristics determine whether the oil is used as food or medicine and, in turn, whether it is even legal or not.
CBD oil falls in the gray area, which is why it is so confusing and potentially dangerous for anyone except those who are gravely ill with few other treatment options. Hopefully, the discussion below will help clear things up for you!
Cannabidiol (CBD) Oil
As described above, manufacturers create medicinal CBD oil by blending cannabidiol with a carrier oil. This active ingredient is either isolated or alcohol extracted from whole cannabis plant matter.
CBD was legalized in all 50 states by the 2014 Farm Bill, which served as the springboard for its explosive growth. However, this approval came with an important caveat. The legislation required the extraction of CBD for academic research or under a state pilot program. Since then, a number of states broadened this narrow definition, which legalized other CBD manufacturing processes. (2)
Hemp Seed Oil
CBD oil is vastly different from hemp seed oil, which is a food and not medicine. It is made by cold pressing the seeds on the cannabis plant. The resulting oil is high in inflammatory omega-6 fats. Hemp seeds contain no THC and hence the oil should technically not contain any either.
Some countries require testing for THC in hemp seed oil to verify purity. Typical requirements are that there are no more than 5-10 or even zero parts per million (ppm) detected in the final product.
Hemp Oil (Hash or Cannabis Oil)
In comparison, hash or cannabis oil does contain high inducing THC. It is also misleadingly known as honey oil.
It comes from aerial parts of the marijuana plant except for the seeds. This medicinal or recreational oil can be made from any of the three sub-species of the cannabis plant – Cannabis sativa, Cannabis indica, and more rarely Cannabis ruderalis.
Hash oil is illegal for recreational use in most states but is approved for medicinal use by a growing list of others. It is usually consumed by eating or smoking. It is also sold in cartridges for use in vaping pens.
In summary, while hemp seed oil is widely recognized as safe and available on health food store shelves all across the country, hemp oil is still regulated as a medicinal only drug in some states and completely outlawed in others. CBD oil falls in the gray area somewhere between the two.
The question that remains to be answered is its safety. Does the narrow legalization of CBD in the 2014 Farm Bill guarantee its safety? Or is it actually more risky than consumers have been led to believe?
CBD Oil Risks
The side effects of consuming cannabidiol are very real though commonly glossed over by those selling it.
Drug Contraindications
CBD oil may potentially interact in a negative way with anti-epilepsy drugs. As of now, only in vitro (test tube) observations exist with no living organism testing proving safety. Drugs that may interact include: (3)
- carbamazepine (Tegretol)
- phenytoin (Dilantin)
- phenobarbital (Luminal, Solfoton, Tedral)
- primidone (anti-seizure)
Side Effects
According to a review of existing research by the journal Cannabis and Cannabinoid Research, the most common side effects of consuming CBD or CBD oil include:
- fatigue
- nausea or vomiting
- diarrhea
- dizziness
- anxiety or depression
- changes in appetite/weight
- Psychosis
While there is a well-known link between psychotic disorders and pot, CBD is generally regarded as anti-psychotic. (4)
How can this be if a CBD side effect is psychosis? (5)
Perhaps this common belief is simply not true!
Psychoactive Effects of Cannabinoids
Perhaps cannabinoid oil purveyors tend to ignore the well-established reactions because the side effect profile of CBD is better than pharmaceutical drugs used to treat similar conditions.
In addition, proponents of CBD oil use insist on its safety because cannabidiol is not mind-altering like its cousin cannabinoid THC.
Research from the 1970s seems to confirm that CBD is well tolerated up to 600 mg without psychotic episodes. (6)
However, more recent research disputes this assumption.
Conversion of CBD to THC
Researcher Kazuhito Watanabe, PhD and his team at Daiichi College of Pharmaceuticals, Japan discovered a disturbing problem with cannabidiol. (7)
They found that CBD converts into THC, the same psychosis-inducing substance found in weed. In addition, CBD converted into two other THC-like cannabinoids known as HHCs (hexahydroxycannabinols). All three produced high inducing symptoms in mice.
This research indicates that THC is not the only mind-altering cannabinoid in hemp. It also suggests the possibility that a person can be exposed to brain-altering, high inducing substances by simply consuming CBD.
Getting High on CBD?
Acidity is necessary for the conversion of CBD to THC and the two psychoactive HHCs. Researchers performed this conversion using artificial digestive juices. The change accelerated in the presence of some kind of sugar (or alcohol).
In people consuming CBD oil, this would parallel as acidity in the stomach. Since people commonly consume CBD oil in sugary lattes, candy, goodies, smoothies or alcoholic beverages, this situation mimics the reality of many people who use it.
Effects of THC Derived from CBD
To test the effects of these components, the researchers then injected mice with small quantities of the THC and HHCs converted from CBD. The researchers tested for the four most common symptoms of THC exposure including:
- Catalepsy – loss of sensation or consciousness
- Hypothermia – drop in body temperature
- Prolonged sleep
- Reduced pain perception
Mice injected with small amounts of THC and HHCs converted in artificial gastric juices from CBD tested positively for all 4 pot exposure symptoms.
Human Studies
Follow-up research in 2016 published in the journal Cannabis and Cannabinoid Research gives additional pause.
More than 40% of epileptic children orally administered CBD exhibited adverse events, with THC like symptoms the most common. In their conclusion, researchers challenged the accepted premise that CBD is not high-inducing.
Gastric fluid without enzymes converts CBD into the psychoactive components Δ9-THC and Δ8-THC, which suggests that the oral route of administration may increase the potential for psychomimetic adverse effects from CBD. (8)
Is CBD Oil Safe for Children?
The takeaway of existing research as of this writing seems to indicate extreme caution when it comes to the ingestion of CBD oil especially by children.
Research definitively shows that THC exposure affects their developing brains in a negative way – perhaps permanently. The important point here is that consuming CBD or CBD infused oil can initiate this THC exposure – not just smoking or vaping pot. The Journal of Current Pharmaceutical Design warns:
The literature not only suggests neurocognitive disadvantages to using marijuana in the domains of attention and memory that persist beyond abstinence, but suggest possible macrostructural brain alterations (e.g., morphometry changes in gray matter tissue), changes in white matter tract integrity (e.g., poorer coherence in white matter fibers), and abnormalities of neural functioning (e.g., increased brain activation, changes in neurovascular functioning). (9)
CBD During Pregnancy
The Journal Future Neurology warns that cannabis exposure crosses the placenta. “Human epidemiological and animal studies have found that prenatal cannabis exposure influences brain development and can have long-lasting impacts on cognitive functions.” (10)
Since CBD partially converts to THC under acidic conditions, women who consume CBD oil for morning sickness or other discomforts of pregnancy should understand that use may mimic using pot directly. Just because CBD oil is natural and works effectively to alleviate symptoms does not mean it is safe for your baby.
Always discuss any supplemental foods with a practitioner before use!
CBD from Hops and Other Non-Cannabis Plants
Some CBD products and oil come from plants other than cannabis. Hops is one that is popular currently. (11)
People that use non-cannabis CBD mistakenly believe that they are safe from THC. The false marketing of these products encourages this line of thinking.
Be warned that no matter where CBD comes from, the potential for conversion of CBD to THC in the digestive tract exists. CBD is ultimately a cannabinoid no matter what plant it comes from. Thus, unless the CBD is applied transdermally or intravenously to avoid the acidic conditions within the digestive tract, the risk for THC exposure and brain-altering effects still exists.
To give you a example of how this works, consider how beta carotene converts to Vitamin A in the digestive tract. It doesn’t matter if the beta carotene comes from carrots, peppers or squash. This nutrient will still potentially convert to Vitamin A. The same principle applies to CBD that is consumed orally. The digestive process can result in conversion to THC no matter what plant is the source of the CBD.
Is CBD Safe for Anyone?
Consumers desperately need more research about the high-inducing effects of CBD-to-THC that could manifest as a result of the digestive process.
The half-life of oral CBD in the body is about 2 days. Thus, depending on how much a person consumes and how often, the potential risk of psychosis could increase over time depending on individual metabolism.
It seems that, as of this writing, the prudent course of action for the cautious consumer is to adopt a wait and see attitude toward CBD and CBD oil products pending further research on the very real potential for mind-altering, pot-like effects.
Some companies are already working to develop synthetic transdermal CBD. This would bypass the gastrointestinal tract and avoid bioconversion to psychoactive THC and/or HHCs. For example, CBD cream is an effective headache remedy and because it is externally applied, can be considered safe even for children.
While the risks of THC exposure from internal use of CBD oil and other products are likely of little concern for gravely ill people who desperately need it, for otherwise healthy people and children, beware! It seems wise until further research is concluded to treat CBD oil, candy, and other products just like any other high inducing drug. Just. Say. No.

Hi – I appreciated all the references you gave and also the low-drama tone of this article.
Brenda
Sarah, thank-you for speaking out on this. I tried one CBD oil pill and got extremely fatigued and also depressed, and I never get depressed. I attributed this as a reaction to the CBD oil and quit taking any more.
Sandra
I stopped reading when I got to the section speaking of Daiichi College of Pharmaceuticals research and findings. Please don’t take any research from a pharmaceutical company as truth either….they have much to lose if people started using CBD in place of pharmaceutical products. Do you know that the drug industry is now pushing for legislation that would make CBD oil illegal and GW pharmaceuticals developed Epidiolex, a ‘proprietary oral solution of pure plant-derived cannabidiol. I am interested on your thoughts on this product being given to children for seizures? Also here is a link to side effects of common seizure medications…as a mother and RN (working in drug safety for big pharma) I would take those listed for CBD oil vs these any day https://www.rxlist.com/seizure_medications/drugs-condition.htm#common-seizure-medications-side-effects. Everything in moderation and under the supervision of a physician that is open to alternative treatments. As a side note…I was diagnosed with an autoimmune disease and use CBD oil 20 -1 ratio. I tried different ratios and manufacturers and found one that gives excellent results with no side effects. This sure beats the poison my neurologist wanted to pump into me which needed me to either be in a cardiologist office to ingest since my pulse could drop to a dangerous low or have frequent liver function test to make sure I wouldn’t go into liver failure. Oh then there was the weekly injection I was told to take on Friday as I would be in bed with flu like symptoms for 2 days …this way it wouldn’t affect my job. Great life that would be…5 days work, 2 days sick. These options led me to look outside the traditional realm. By the way…I am not gravely ill. All I know is my doctors are stumped ….11 years post diagnosis and no progression of the disease and no side effects. I stopped seeing him years ago because all he wanted to do was put me on pharmaceuticals…last I saw him he shook his head and said he couldn’t argue with success. Too bad this article didn’t share research on the pros of cannabis…this way the reader could make an educated choice based on all facts or so called facts.
Sarah
I think people are being inundated with the pros of CBD already. It’s everywhere. If you go on social media, anytime someone mentions a problem with this or that, the immediate comment is “take CBD oil!”. This article specifically attempts to present the other side.

Hi Sarah,
It seems your readers are either not too bright, you correct their assumptions, or skimmed through the article and stopped at mice. Thank you for posting this! The Greek word that we derive pharmaceuticals in our language has a root in sorcery. This is another of the devil’s ploy to deceive. The bible clearly states that sorcery is from the evil one, and he is hell bent on lies and deception. Drugs are useful in appropriate usage, but this craze is out of control.
Franny
Could you please list your references for this satatement? “However, more recent research disputes this assumption.” I am really interested in what was done in the studies were psychosis was found as a side effect.
Thank you.
Sarah
Yes, the sources including studies are linked in the post for your reference.
V
You counter most of your arguments in your response. I am sure you can/will not acknowledge this but for the others who are reading this, I too have seen the “couch potato” syndrome. Bright minds, smoking, ingesting away and most never live to their fullest potential because the RESEARCH has shown THC affects the part of the brain that motivates! It demotivates!
RSMFarms
Sarah, thank you for this information. Can CBD be applied externally thru the skin or used in an oil diffuser? I’m curious.
Sarah
Many substances readily are absorbed via the skin and CBD clearly is one of them as companies are developing transdermal synthetic CBD applications, I am just not aware of how much or how often a person applying the oil at home would use as I’ve not seen any studies on this.
Nora
Hi Sarah, I’m currently researching if CBD oil might preventatively help with my girl of 10. She suddenly got seizures since last year. 3 in 1 year, during her sleep. She is not Taking medicines. I had hoped your article gave us readers advise What to buy, How much intake, What to look for as you indeed write…. nowadays you can buy it everywhere… so I want to be sure to get great quality …so this stopped me buying just one of the many bottles ..,, also wonder if quality does need to cost more than $100 dollar per bottle …
Sarah
As you can see from the study cited in the article above, children with seizures given CBD have a very high rate of negative reactions. I would suggest examining other natural avenues for resolving her condition under the care of a respected functional doctor in your community instead of attempting a DIY approach with CBD at home.
Arija
HI there Sarah, I’ve never responded to a article, but could you list your references for this one? Its really important for everyone to acknowledge there is fact, and opinion. This seems like it strikes a cord with you, and is something you are very passionate about. Make sure to write out your sources and references so people can dig deeper for themselves. The health and well being of our future populations is of extreme importance.
What works for some, will not work for others, and for ANY READERS out there, please be sure to take in information with a grain of salt, and seek professional expert advice on topics like this.
Sarah
Hi Arjia … all 11 sources are linked within the article. Scanning through it, you should easily see them.

This is the kind of biased reporting that makes me seriously question how WAPF reached its other conclusions. You might want to take a look at 5000 years of recorded history, anecdotal evidence suggesting that for 99.9% of the population, cannabis is safe in all its forms. Anecdotal has been good enough for us regarding vaccines, GMOs and glyphosate (at least glyphosate is finally getting some good data to support our wild claims that it’s dangerous.) But when it comes to cannabis, WAPF ignores that, going with “science” with loopholes so big, if you can read, you can drive a truck through them.
Did you know that doctors fought cannabis being made illegal because it was such a valuable healing herb? Then they were threatened and quieted down. Read “Chasing the Scream”.
I’ve smoked it off and on all my life (since age 14) as have too many of my friends to count and used it medicinally to great effect as have millions of others. I’m 30 years sober and have been a drug and alcohol counselor for most of those years. Cannabis is a valuable herb. As are LSD and ayahuasca and ecstasy, mescaline, even cocaine. In fact, I suffered a psychotic break after a bad LSD trip at age 18. I recovered without drugs or therapy. It was not easy, the point being that even a psychotic break is not the end of the world and is a blip in a long fruitful life.
I had a very long discussion with Kim Hartke on Kelly’s blog and not doing that again. I hope someone else takes up the mantel. Or not. Cannabis will be legal nationwide in short order and time will prove which position is correct. Prohibition never works. It didn’t with prostitution or alcohol or drugs or alternative medicine or raw milk.
This WAPF cannabis propaganda is very distressing. I’ve been a chapter leader for 8 years and just resigned because I can’t ignore such an ill-informed position. I am a cannabis activist, I’ve seen the healing up close and personal and have never seen anything negative other than “couch lock” (which I have also suffered: two hours of not being able to get up from the sofa, lol). Cannabis is not for everyone just like raw milk is not for everyone. But the hysteria you are espousing is flat wrong. I wonder what the motivation could possibly be.
Sarah
As I wrote at the beginning of this article, I am not questioning the benefits of cannabis which indeed helps and provides comfort to a lot of very sick people. I even voted to legalize medical marijuana here in Florida … it does have its place, no doubt about that.
But giving CBD to children and aggressively selling it to otherwise healthy adults as some sort of silver bullet panacea for literally every health issue under the sun without disclosing the very real potential for psychotic effects … potentially permanent in children – is WRONG.
