What side effects have been observed?
Studies have found that the benefits far outweigh the potential side effects of CBD.
And in comparison with conventional medication, there is significantly less risk of side effects.
The following side effects were occasionally reported in the studies we examined:
- Fatigue - CBD is considered a natural sleep aid, it is also used as a sedative and may cause drowsiness. You should therefore be careful when driving a car or operating machinery.
- Diarrhoea - indigestion has been reported sporadically after consuming high amounts of CBD.
- Change in appetite.
- Slight dizziness or light-headedness - CBD can cause a temporary small drop in blood pressure. A cup of tea or coffee can help here.
- Dry mouth - like other cannabinoids, saliva production may be temporarily reduced. The mouth can feel dry and cause thirst.
- Increased tremor in Parkinson's patients - Early studies have shown that CBD can worsen tremor and muscle movement in people with Parkinson's diseas
- Inhibition of P540 enzymes - particularly important for interactions with other drugs. In this context, the so-called grapefruit test must be observed (see below)
- People with glaucoma should avoid CBD as it can increase intraocular pressure
Collected experience on side effects of CBD
Our team has evaluated hundreds of experiences from consumers about side effects of CBD. If you do not suffer from epilepsy, glaucoma or Parkinson's, side effects have hardly occurred.
The most common side effects from the experience gained are fatigue, upset stomach and increased appetite.
However, these are all very mild and some consumers even point out that it is important to eat enough food whilst taking CBD products.
Can CBD cause headaches as a side effect?
The most commonly reported side effects are dizziness, tiredness, headache and a dry mouth. It is interesting that some people report headaches with CBD use because one of the most common uses of CBD is to treat migraine headaches.
The Skaggs School of Pharmacy and Pharmaceutical Sciences - University of Colorado, conducted a study in 2016 to test the use of medical cannabis to treat migraine headaches.
The results were very promising. Research statistics concluded that CBD has helped reduce the incidence of headaches by more than 50%, from 10.4 to 4.6 headaches per month.
Despite these conclusions, doctors are debating whether CBD oil can also cause headaches.
A drug that minimises a particular condition can trigger the same condition in different situations. In a way, it can be compared to many modern drugs, for example, acetaminophen is good for headaches, but it can also cause them.
According to Cannabis and Cannabinoid Research (2017), CBD can cause diarrhoea, fatigue, and problems related to weight and appetite. This study also never mentioned headaches as a possible side effect of CBD oil.
Are there any side effects of CBD on dogs?
As with everything you give your dog, it is advisable to check whether CBD is safe for your four-legged friend. While there is some debate in the veterinary community about the effectiveness of CBD, CBD oil is generally considered to be very low risk for dogs.
There have been animal studies with CBD. And it has been found that in some dogs, mild side effects can occur. The most common being - like people - increased sleepiness. As always, proper dosage is important.
If your dog eats too much, it can lead to dry mouth, diarrhoea or dizziness. These side effects for CBD in dogs are comparable to those in humans.
While CBD oil is considered relatively safe, you should contact a veterinarian if you have any questions because not all CBD oils are made the same way or contain the same ingredients.
We advise you to check how the product is made and to make sure that it does not contain any harmful additives. Under no circumstances should you give your dog products that contain THC, because THC is very harmful for dogs.
