Does the use of CBD oil have side effects? CBD is a natural substance, a cannabinoid from the cannabis/hemp plant, whose positive properties on the human organism are not only attributed by scientists and physicians but by people all over the world who have experienced its healing and therapeutic abilities. Even though it is a natural substance and because of the fact that we have our own cannabinoid system (endocannabinoid system), it looks as if it has been created for us, nevertheless the question arises whether CBD has side effects. And if so, which one? Under which circumstances? And at what dose?

Really interesting reading all of the comments. I started using hemp oil capsules about 5 weeks ago mainly to treat aches and pains. I feel though like i’ve been going slightly mad, this is virtually impossible for me to describe, although i’ve been extremely happy, jokey etc, like everyone in the world is my best friend, my mind though is not at all right, everywhere I’ve been including familiar places like my own home seem so different, I almost feel like I’m looking at myself from a distance, I wish I could explain it better but it’s impossible to do so. I’m just on another planet. I’ve had stomach problems and I’m really off food, I’ve always been a hungry guy but not at the moment. I’m sure this product is fantastic for most people but sadly it doesn’t seem to suit me, I took my last capsule this morning, it suddenly hit me that is was the hemp causing the change in me. I’ll see what happens in the next few days. best wishes to everyone, like I said, everyone is my best friend at the moment.


Featuring the same benefits as our pure RSHO™ hemp oil in a reduced potency, another of our midrange products, RSHO™ liquid, contains 31 mg of CBD per serving. Available in Green, Blue, and Gold Label oils, RSHO™ liquid combines our flagship RSHO™ with medium chain triglyceride (MCT) oil derived from wholesome coconut oil and sustainably sourced palm oil.

There’s still a lot of unknown territory, but early evidence for CBD’s efficacy is more than enough to justify further large-scale clinical studies — some of which are already in the works. These studies also point to the variety of effective ways to take CBD. This is an important point to keep in mind if you find yourself shopping for CBD products and wondering if the best CBD for pain is a topical, a tincture, or a vape product.

During period, women usually experience alot of pain due to menstrual cramps. The cramps begin up to a week before the period starts, and can continue during and even after the period is over. This is a terrible situation and can affect some women so severely such that it can make it difficult for them to go about with their daily activities. Fortunately, cannabidiol oil can help alleviate the feeling of the menstrual cramps and can allow them to get back to their day to day life.


Instances of PTSD (abbreviation for Post Traumatic Stress Disorders), have been on the rise in recent years. It is something which many veterans come home with after serving many years over seas, and is also be found in people who have been through severe trauma. The condition can make people go to extremes, and can even make some take their own lives. If you are suffering from PTSD, the good news is that CBD oil can be of help. CBD oil is well known to produce anti anxiety and anti-inflammatory effects. After it is ingested, it actually slows everything down and induces a calming feeling.
Children: A prescription cannabidiol product (Epidiolex) is POSSIBLY SAFE when taken by mouth daily. The most common dose used is 10 mg/kg daily. Higher doses of 15-20 mg/kg daily may be used in some children, but these higher doses are more likely to cause side effects. This product is approved for use in certain children 2 years of age and older, but has been used in children as young as 1 year of age.
Consume CBD oil via edibles to enjoy a sweet treat. There are many edible products available for purchase that contain CBD oil as an ingredient. These are often in the form of gummies or other candies, but also come as an edible liquid that you can mix into foods, such as smoothies. If you live in a state where it’s legal, go online and choose whichever edibles sound good to you. After purchasing, make sure to read the instructions and take them as directed.[2]

And lastly, don’t hesitate to speak with a marijuana doctor or health professional about using CBD oil. And please note,  it is not our goal for any of the information on here to come across as clinical advice or medical recommendations. If you live in a state with legalized medical marijuana, make sure you take full advantage of the resources that are available to you – getting a licensed MMJ card is easier than it has ever been before, and it could very well be one of the best decisions you’ve ever made for yourself.
CBD works by attaching itself to specific receptors of the body’s own endocannabinoid system. The human body is known to produce cannabinoids of its own, which affect the cannabinoid receptors CB1 and CB2. The CB1 receptors are generally found in the brain, and deal with pain, mood and emotions, movement, appetite, among others. THC acts upon the CB1 receptors. Meanwhile, CB2 receptors are more commonly found throughout the immune system, affecting inflammation and thus pain. CBD is thought to act upon these receptors, by influencing the body to produce its own cannabinoids in order to rebalance itself.
Hi, I just started using CBD Oil (NULeaf) concentration 50mg/ml. I only took 10 drops sublingually (below tongue for 60 seconds) as suggested the first time round and had the same experience. I felt great within 30mins afterward, my shingles pains and joint pains/skin pain subsided almost 90% and brain fog (probably from sinus problems) lifted like a veil. I was so happy. Next morning I took 4 more drops as I had a slight headache (like a dehydration headache) by the afternoon I had a horrible migraine (which I haven’t had in 6months) and vomiting throughout the night. I stopped the CBD but for the next 2 days I still had headaches in the back of my head (like dehydration headaches). Now I feel very uneasy taking the oil again. I really want this to work, as the shingles related nerve pain is driving be crazy and my anxiety levels anyways are thru the roof. I am wondering if you’ve found a solution and are still taking the CBD. I will start again today with a 3 drop dose once a day and see if I can come up with a dosage that doesn’t cause me headaches and still do the job I intended it for.

Another reported side effect of CBD administration is an unpleasant dry sensation in the mouth. This effect seems to be caused by the involvement of the endocannabinoid system in the inhibition of saliva secretion. A study published by Argentinian researchers back in 2006 showed that cannabinoid receptors (type 1 and 2) are present in the submandibular glands which are responsible for producing saliva.

Majority of cannabinoids have been shown to have positive effects on the immune system, particularly the CBD oil, as it helps regulate over-active immune systems. This basically means less susceptibility to various kinds of allergens. Moreover, since CBD oil contains a high amount of omega 3 which supports the growth of micro organisms which live in the intestines, it can aid in enhancement of the immune system, and your body will be able to fight flu, illnesses and germs more easily.

Acne can have a very devastating impact on certain people. Acne can actually lower one’s self esteem and confidence. The good news is that recent research studies have shown that CBD oil can be a great way of treating acne. A recent research study by Journal of Clinical Investigations revealed that CBD oil helps to in lowering production of sebum which leads to acne. This is because CBD oil decreases the lipid synthesis and the proliferation of sebaceous glands, and also has anti inflammatory effects on the sebaceous glands, therefore delivering a therapeutic agent for treatment of acne.
A research study posted to Addictive Behaviors shows that cannabidiol oil helps in treatment for substance abuse. According to the study, continued use of cannabidiol oil helped reduce tobacco consumption when used for 1 week. The participants in the research study randomly picked a placebo or CBD. They were then urged to use what they had picked whenever they felt like taking a cigarette. The participants with the placebo didn’t experience any decrease as opposed to the particiapnts who took CBD and decreased cigarette consumption by about 40%.
A natural plant extract, CBD (or cannabidiol) has made a huge stir in the health scene over the last decade. It’s not hard to find plentiful anecdotal evidence of its benefits — people are using CBD for pain relief, mood regulation, cancer prevention, even seizure reduction. But if you’re in pain, you’re probably looking for more than anecdotal evidence. We get it — and we’re here to help.

Honestly, I began to wonder if I was just experiencing the placebo effect. But on the one day, I didn’t take my CBD oil, I ended up picking a fight with my boyfriend (totally my fault) and let a few off-color remarks by a family member mess with my mood. Truly, I feel like it was a bit less anxious, both of those incidents could have been diverted.
This review paper on the safety and side effects of cannabidiol by the NCBI, for example, suggests that controlled cannabidiol administration is safe and non-toxic in humans and animals. It also does not induce changes in food intake, nor does it affect physiological parameters like heart rate, body temperature or blood pressure. Also, according to this review paper, “high doses up to 1,500 mg/day of CBD are reportedly well tolerated in humans.”
For some people, however, regular strength CBD just doesn’t cut it. If you’re one of those people, you may require something a lot stronger. If you think that CBD “doesn’t work”, then it’s possible that you might need to step it up to something stronger. Whether you’ll be good with a 1000mg high-strength CBD oil or if you need to step up to the big leagues with the Hemp Bombs 4000mg vape juice is a matter of personal preference. Everyone’s body is different. What works for someone else may not work for you. Experiment and find the perfect dosage that works best for your unique needs.

Transparency: Fab’s website features third-party lab results for most products. They only have a lab test for one of their tinctures though (which shows results for cannabinoid potency, as well as contaminants like pesticides). Customer service pointed out that the same CBD oil is used for all their products, but since potencies do vary, we appreciate companies that show potency testing for all products.
Schizophrenia. Research on the use of cannabidiol for psychotic symptoms in people with schizophrenia is conflicting. Some early research suggests that taking cannabidiol four times daily for 4 weeks improves psychotic symptoms and might be as effective as the antipsychotic medication amisulpride. However, other early research suggests that taking cannabidiol for 14 days is not beneficial. The conflicting results might be related to the cannabidiol dose used and duration of treatment.
