CBD side effects: which side effects can occur with CBD?
By Vapor Spirit Fachteam

Cannabidiol (CBD) is a natural component of the hemp plant and is used by many
people in everyday life. Products such as CBD oil, capsules or CBD vapes are enjoying
growing popularity because they are versatile. Information on CBD oil side effects and CBD drops side effects is searched for particularly often.
The effects and side effects, as well as the effects of CBD on the body, depend
largely on how CBD oil is taken and on the individual dosage.
But as with any substance, the same applies here: every body reacts differently. That is why
many users ask the legitimate question:
Which side effects can occur with CBD?
In this article, you will receive an objective and neutral overview of possible
accompanying symptoms, scientific assessments and notes on safe
use.
Is CBD generally safe?
The World Health Organization (WHO) has already determined that CBD is generally
considered well tolerated and has no potential for dependence. Unlike THC, CBD
also has no intoxicating effect.
However, it is important to note:
How CBD works in the body can vary individually β depending on factors such as:
- Dosage
- Body weight
- Metabolism
- Time of intake
- simultaneous intake of other substances
Many users report good tolerability. Nevertheless, in individual cases
mild side effects can occur.

Common side effects of CBD β rare, but possible
Tiredness or drowsiness
CBD can have a relaxing effect. Some users therefore report
tiredness, especially at higher doses or when taken in the evening.
π This effect is usually temporary and depends heavily on
the individual reaction.
Dry mouth
A dry feeling in the mouth can occur temporarily, as CBD can
influence saliva production.
π Tip: drinking enough water can help.
Slight drop in blood pressure
In individual cases, CBD can slightly lower blood pressure β especially shortly after intake.
π People with low blood pressure should dose carefully.
Changes in appetite
Some users report slight changes in appetite β both increased and
decreased.
π This effect is individual and usually temporary.
Mild digestive complaints
In rare cases, the following can occur:
- Nausea
- Stomach sensitivity
β especially at higher doses or with unaccustomed intake.
Rare accompanying symptoms
In rare cases, the following may also occur:
Dizziness or light-headedness
Can occur if the body reacts sensitively or blood pressure drops briefly.
Irritability or mood swings
Reported very rarely β often in connection with other factors (e.g. stress or interactions).
Interactions with medication
CBD is processed in the liver via the so-called cytochrome P450 enzyme system β the same system that also breaks down many medications.
CBD can therefore influence the effect of certain medications.
Particular caution applies with:
- blood thinners
- antidepressants
- antiepileptic drugs
- painkillers
- blood pressure medication
π If you take medication regularly, you should seek
professional advice before use. People who have to take medication regularly should clarify the use of CBD with a professional beforehand.
Quality matters β not all CBD is the same
A decisive factor for tolerability is the quality of the product. Not all CBD oils or CBD preparations are the same: the quality of the CBD oil largely determines how well a product is tolerated.
What you should look out for:
- β Laboratory-tested products (COA)
- β Full spectrum instead of isolate
- β No synthetic additives
- β Transparent origin

How you can avoid side effects
Gradual dosing
Start with a low amount and increase it slowly.
Regularity instead of overdosing
Consistent intake is often more sensible than high single doses.
Correct intake
Many users prefer sublingual use (under the tongue), as this allows
even absorption. If CBD is taken orally instead, for example as a capsule, it usually takes a little longer for the effect to set in. Correct intake of CBD thus contributes significantly to avoiding unwanted effects.
When should you avoid or pause CBD?
Particular caution is required in certain situations: pregnant and breastfeeding women should generally refrain from taking CBD, as there is not yet sufficient safety data on this.
- Pregnancy and breastfeeding
- severe liver disease
- simultaneous use of medication
- known intolerances
Scientific assessment
Studies show that CBD is generally well tolerated. Possible side effects
are usually classified as:
- mild
- rare
- temporary
(Source: Chesney et al., 2020, Neuropsychopharmacology)
Conclusion
CBD is generally considered well tolerated, but β as with many natural substances
β mild side effects can occur.
These are usually:
- mild
- temporary
- individually different
Conscious use and the choice of high-quality products help
to minimise possible risks.
Frequently asked questions about CBD side effects
Below, we answer frequently asked questions about cannabidiol (CBD) and possible side effects β from the effect on the psyche to interactions in chronic pain.
Can CBD affect the psyche?
Unlike THC, CBD is considered non-psychoactive and does not cause a high. In rare cases, users report irritability or mood swings, usually at high doses or in combination with other substances.
Can CBD put a strain on the liver?
As CBD is metabolised via the liver, altered liver values can occur at high doses or with simultaneous use of medication. People with pre-existing liver conditions should clarify intake with a doctor beforehand.
Does CBD affect the brain?
CBD interacts with the body's own endocannabinoid system, which regulates mood, sleep and pain perception, among other things. Unlike THC, CBD does not alter perception.
Can CBD cause a racing heart?
As CBD can influence blood pressure, some users report a briefly altered heartbeat. If you have existing cardiovascular disease, it is advisable to consult a professional beforehand.
Does CBD increase intraocular pressure?
Clinical studies to date do not indicate a relevant increase in intraocular pressure caused by
CBD, but reliable long-term data are still limited.
Can CBD cause headaches?
Headaches are among the rarer side effects and tend to occur with dosing errors or low-quality CBD products. Pure CBD from laboratory-tested products reduces this risk.
