CBD in cannabis plants is one of more than its 100 cannabinoids and is the second most famous. Although its popularity has increased notably throughout recent years for its many different health benefits, scientists and researchers have conducted several studies on cannabidiol and CBD products. From those research and studies, some side effects of CBD have come out. But they are relatively minimal and rare.

Now, if you are here, we assume you have questions like – what are the side effects of CBD? What are the negative side effects of CBD oil? This article will help you know all your answers together with the bad side effects of CBD and the possible ways to avoid them.

What are CBD’s Side Effects?

Generally, CBD is considered as a safe substance at the time of applying topically or taking orally. But you should know that the amount of CBD you are ingesting can affect whether you experience any side effects or not. Some other factors may add to the bad effects of CBD. They include any health issues you might have, your age, body weight, any medication you might be taking, and any environmental factors.

However, some potential side effects of CBD are found while using it majority of which are mild. Even though experiencing side effects from CBD is rare for people, some of the most commonly reported ones include:

  • Diarrhea
  • Nausea
  • Tiredness
  • Sleepiness
  • Changes in weight
  • Changes in appetite
  • Low blood pressure
  • Dry mouth

CBD Products and Their Side Effects

Since there are different CBD products, it is better to explore all the different types and their potential side effects.


CBD oils and tinctures belong to this category. After placing the drops of these products under the tongue and keeping them there for a couple of minutes, the CBD is absorbed through tiny capillaries directly into the bloodstream.

Common side effects from this type of use of CBD products include dry mouth, decreased appetite, fatigue, potential CBD-drug interactions and changes in bowel habits.


CBD vape pens are widely available commercially and contain hemp extracts mixed with thinners such as vegetable and propylene glycol or a mix of both. Regular use of propylene glycol has no relation with toxic effects but, reports of people have been found to experience allergic reactions like rashes, headaches, and nausea after using a CBD product infused with the thinner.

Don’t forget that inhaling smoke or vapor of CBD products may often cause lung irritation if the products use dangerous solvents and additives. Other side effects may include dry mouth, lightheadedness, and dizziness.


People use CBD topicals to remove localized discomfort- pain or inflammation and improve skin health. But not all CBD topicals are made the same. Aside from the risk factors like poor-quality hemp, cheap extraction, and lack of third-party testing, the presence of other ingredients may also be responsible for the potential side effects of CBD topicals.

Some of those ingredients may cause allergies. But others have a bad reputation in the skincare industry as straight irritants that include additives like parabens and sulfates. A few of the side effects caused by CBD topicals may include skin rash, hives, and itching. To avoid the side effects of CBD topicals, you should choose organic products.
