Are There Any Side Effects When Using CBD Oil

cannabis side effects

Everyone seems to be talking about CBD oil these days. Well, most of them have good reason to. CBD is one of the many cannabinoids found in the marijuana plant. It is relatively (back to this word later) safe because it is non-addictive, non-psychoactive and non-toxic. It is known to be anti-inflammatory and anti-oxidant, so it is great for the management of a range of health issues. CBD oil is also increasingly popular because it can be consumed in several ways like skin creams, soft gel capsules, tincture, edibles and vapes. 

Studies have revealed that the body can tolerate CBD oil in doses of up to 1,500mg. This means that it is relatively safe to consume CBD oil. The implication is that there are doses of CBD that can be harmful. If there are harmful doses, are there also side effects when using oil? These are some of the grey areas around the use of CBD oil. This article will answer one of these questions, so read on to find out more.

Are There Any Side Effects When Using CBD Oil

 Yes, there are side effects to using CBD oil. Here they are: 

Dry Mouth

Dry mouth, aka “cottonmouth,” is a common side effect of CBD oil because cannabinoids inhibit saliva production. CBD’s interaction with a CB receptor (submandibular gland ) in the mouth tends to reduce the production of saliva so users should expect this dryness of mouth

Low Blood Pressure

When taken in really high doses, CBD oil can cause a drop in blood pressure. So while it has the potential to cure hypertension, it can cause hypotension when the dose is very high. So people with blood pressure issues (high and low) have to be careful with their use of CBD oil for this reason. Low blood pressure can lead to a feeling of light-headedness that can be disturbing. High doses of CBD can result in fatigue and drowsiness. So executing tasks that require concentration and mental acuity could be disastrous in such situations.


CBD oil has strong gastroprotective qualities, but if it's not isolate CBD, then the other ingredients in the CBD oil can irritate the stomach lining and cause diarrhea when consumed in large amounts. This often occurs when it is consumed in high doses or the because of the carrier oils used with it.

Interactions with Other Medications

CBD can inhibit the liver's ability to metabolize certain drugs, thus leading to high levels of toxic substances in your body. It does this by neutralizing the effect of the enzyme cytochrome P-450, which is responsible for processing pharmaceutical drugs. 


The good part about these side effects is that they can be avoided. To consume CBD oil without any adverse reactions, users have to make sure that they are using quality CBD oil from a certified outlet. They also have to be mindful of the dose of CBD they are ingesting. It is highly recommended that users should consult a doctor before consuming CBD oil.
