Many people have had good experiences with the effects of CBD . But what about its side effects?
To date, we do not have any precise documentation regarding the side effects of CBD. It has been shown in previous scientific studies that CBD is absorbed very well by the human body .
However, side effects occurred sporadically or mildly during some tests. We have taken care to examine some of them.
What side effects have been observed?
Studies have shown that the health benefits far outweigh the potential side effects of CBD. The side effects of CBD compared to conventional drugs are milder.
According to some studies, the following side effects have been reported in isolated cases:
- Fatigue – CBD is considered a natural sleeping pill and is therefore also used as a sedative. So you have to be careful if you want to drive.
- Diarrhea – Digestive disturbances have been reported following heavy CBD consumption.
- Changes in appetite.
- Mild dizziness or vertigo – CBD can cause your blood pressure to temporarily drop slightly. A cup of tea or coffee will be able to restore your tone.
- Dry mouth – as with other cannabinoids, saliva production may be temporarily reduced. The mouth may seem dry.
- Increased tremors in patients with Parkinson’s disease – early studies showed that CBD can worsen tremors and muscle movements in people with Parkinson’s disease.
- Inhibition of P540 enzymes – particularly important for interactions with other drugs. In this context, the so-called grapefruit test (see below) should be observed.
- People with glaucoma should avoid CBD because it can increase intraocular pressure .
A medical consultation is advised, especially during pregnancy, because CBD influences specific proteins. This can lead to unwanted changes in placental function.
Interactions Can Occur When Using CBD
Interactions can cause unwanted effects if you take other medicines at the same time. The pharmacological result can be improved, but it is possible, however, that the effect is weakened or, in the worst case, even eliminated. Additionally, unwanted side effects may result. Experts assume that CBD oil can interact with certain medications when ingested.
Before consuming CBD, you should discuss with your doctor whether you want to take CBD with other medications . In this context, American scientists regularly mention the Grapefruit Test.
This is because the individual active ingredients in grapefruit interact with drugs similar to CBD. Both have chemical compounds that inhibit the expression of certain cytochrome P450 enzymes. This family of enzymes metabolizes most of the drugs used to treat humans.
For this reason, doctors regularly consume grapefruit while taking certain medications. If your doctor advises you to avoid grapefruit during treatment, you should refrain from taking CBD .
The accumulated experiences on the side effects of CBD
Our team has evaluated hundreds of experiences from American consumers on the side effects of CBD. If you don’t have epilepsy, glaucoma, or Parkinson’s disease, the side effects are very limited .
The most common side effects of the collected experiences are fatigue, upset stomach and increased appetite. However, they are described as being very light. Some consumers stress that it is essential to ensure adequate food intake.
Can CBD cause nausea or diarrhea?
Indeed, there have been isolated cases of nausea and diarrhea in subjects that have been the subject of scientific studies. This was the exception. The vast majority of subjects had no problem with CBD according to recent studies.
The best part is that CBD is also used to fight overweight and diarrhea!
CBD for nausea?
Some studies have shown that CBD even has a special effect on combating nausea. CBD, a non-inflammatory cannabinoid, interacts with receptors that release serotonin and has been shown to be given in relatively low doses to relieve both nausea and vomiting .
Similar effects are also attributed to the psychoactive agent in the cannabis plant, THC. THC fights nausea by docking with CB1 receptors. Cannabidiol (CBD), on the other hand, interacts with serotonin receptors and can counteract the feeling of nausea. Both substances could therefore reduce nausea. Some preclinical reports suggest that CBDa, the acidic form of CBD, is even more effective.
CBD is therefore often used in cancer patients who suffer from severe nausea as a result of chemotherapy.
CBD for diarrhea and constipation?
Diarrhea and constipation can also be treated with CBD , but they can also be a side effect of this herb. Some people have reported mild indigestion, including diarrhea, after taking high doses of CBD. In this case, it is recommended to reduce the dose or discontinue use.
Can CBD cause headaches as a side effect?
The most commonly reported side effects are dizziness, fatigue, headache, and dry mouth. Interestingly, some people report headaches associated with using CBD, as one of the most common uses of CBD is for treating migraines .
The Skaggs School of Pharmacy and Pharmaceutical Sciences at the University of Colorado conducted a study in 2016 to test the use of medicinal cannabis to treat migraines. The results have been very promising. Research statistics concluded that CBD helped reduce the frequency of headaches from 10.4 to 4.6 headaches per month, or nearly 50%.
Despite these findings, doctors are wondering if CBD oil can also be the cause of headaches . A drug that minimizes a certain condition can cause the same condition in different situations. In a way, it can be compared to many modern drugs, for example paracetamol is good for migraines, but it can also cause them.
According to Cannabis and Cannabinoid Research (2017) , CBD can cause diarrhea, fatigue, and weight and appetite- related problems .
Does CBD cause side effects in dogs?
As with anything you feed your dog, it is advisable to check whether the CBD is safe for our four-legged friends. Although the effectiveness of CBD is the subject of debate within the veterinary community , CBD oil is generally considered to be very low risk for dogs. However, some dogs may experience mild side effects, the most common being increased drowsiness, such as in humans. While the correct dosage is important, there is no risk of fatal overdose with CBD oil . If your dog takes too much, he may have a dry mouth, diarrhea, or dizziness. The side effects of CBD in a dog are similar to those in humans.
Although CBD oil is considered relatively safe , you should speak with a veterinarian if you have any questions. Because not all types of CBD oil are the same. We recommend that you check how the product is made and make sure that it does not contain harmful additives . Never give your dog products that contain THC, as THC is very harmful to dogs.
