Quels sont les effets secondaires du CBD ?

What are the side effects of CBD?

Romain Lyomat

Cannabidiol is one of over 100 known cannabinoids that can be found in cannabis and hemp plants. It is particularly recognized for its benefits on our metabolism and is consumed by millions of people around the world.

But what about its side effects?

If we are to believe < span style="font-weight: 400;">the study conducted in 2011, the molecule is not considered dangerous for the health, and has only a few rare cases of identified side effects.

Others researchwork carried out in 2017 confirmed the favorable safety profile of CBD, adding that any adverse effects were indeed both mild and infrequent.

CBD Adverse Effects

In most clinical studies, tests were performed with high doses of Cannabidiol to assess side effects.

In these case studies, the adverse effects observed were as follows:

  • Dry Mouth
  • Drowsiness and fatigue
  • Loss of appetite
  • Nausea
  • Diarrhea

Another < span style="font-weight: 400;">study also revealed that Cannabidiol has the ability to lower blood pressure in humans. This ability may be beneficial for some but may be a problem for people with low blood pressure.

Is CBD addictive?

Cannabidiol is not addictive of any kind and there are no Cannabidiol withdrawal symptoms when you stop consuming it.
The World Health Organization (WHO) also indicated in a report published in 2017, that "CBD exhibits no effects indicative of the potential for abuse or dependence."

Does CBD make your eyes red?

Red eyes are caused by the THC in CBD flowers. THC actually lowers the pressure in the eyes, while increasing blood flow, which can cause redness. It is this drop in eye pressure that promotes the treatment of glaucoma.
Redness can also come from smoke when it enters your eyes.

Can you overdose on CBD?

Research mentioned above indicates that high doses of Cannabidiol are generally well tolerated.
Others work however revealed that extremely high doses of Cannabidiol could cause liver damage in some mice, but in amounts that were nearly impossible to take. (equivalent to 50,000 mg per day for several days in a row for an 80 kg adult).
Overdose is therefore not identified as a particular risk for Cannabidiol.
Even if you take very high doses, you will not die, but you may be at risk of adverse side effects, such as nausea, diarrhea, fatigue and lethargy.

Potential interactions

CBD can also affect your body's ability to process certain medications, including blood thinners. Therefore, if you are taking medication, talk to your doctor before consuming it, to avoid any drug interactions.

CBD and fertility, pregnancy and breastfeeding

Cannabidiol may be recommended to help with fertility, largely due to its relaxing properties. However, searches carried out in 2019 concluded that CBD could have a harmful effect on animal embryos and fetuses.
Its consumption is therefore strictly not recommended during pregnancy or breastfeeding.


Side effects exist, but remain limited.
Apart from the particular cases mentioned above, you take little risk by consuming CBD.
The challenge is above all to control your consumption, as you would for any product.
