5 Potential Side Effects of Using CBD Oil

September 19, 2019 Bionativa

With the growing popularity of CBD oils numerous myths created around them have been widely spread by the media. Some good and some bad. No matter what they say, it can’t be denied that cannabidiol supports the users well-being and overall health. However, as in the case of any other dietary supplement, it may also cause side effects. But in reality, how often do they occur? Are they serious?

CBD is one of the safest cannabinoids and has a number of properties that help with multiple health issue symptoms. CBD products are widely known to be beneficial for your health and well-being.

Although technically it’s cannabis, it’s derived from marijuana, the extraction methods insure that it doesn’t contain tetrahydrocannabinol (THC), so it’s not psychoactive. It interacts with the body’s native endocannabinoid system (ECS) to reach homeostasis and optimal health.

However, despite all the health benefits it offers, some people taking CBD oils have occasionally mentioned:

  • having a dry mouth,
  • dizziness,
  • drowsiness,
  • reduced blood pressure,
  • negative effects on other medication such as delaying or suppressing their effects.

What potential side effects does CBD oil cause?

1. Dry mouth

One of the potential side effects of using CBD oil is the unpleasant feeling of having a dry mouth. While using cannabidiol, the endocannabinoid system stops producing regular amounts of saliva, thus leaving the mouth feeling dry. A study published by Argentinian researchers in 2006 shows that cannabinoid receptors are found in the submandibular glands responsible for the production of saliva. Their activation changes not only the amount produced, but also its consistency.

This side effect is experienced by quite a few people who use CBD oils. However, it’s very easy to overcome by staying hydrated. Then the dry mouth feeling doesn’t occur at all or becomes hardly noticeable.

2. Dizziness

Another potential side effect of using CBD oil is dizziness, although this usually tends to occur when taking higher doses of CBD. Dizziness, similarly to dry mouth, may appear immediately after taking CBD oil. It may be accompanied by light headaches, blurred or vague vision and problems with maintaining balance.

The temporary drop in blood pressure is the reason such symptoms occur. Drinking a cup of coffee, tea or any other caffeine-based drink is more than enough to ease this uncomfortable feeling.

This potential side effect is short-lived and easy to overcome, and it usually passes after a maximum of 10 minutes. It’s worth keeping this in mind when taking cannabidiol, to make sure that there is enough time to rest and restore the regular blood pressure when taking one of the daily doses of CBD.

3. Drowsiness

Drowsiness can also be one of the other potential side effects of using cannabidiol that people mention. It’s usually felt after taking a high dose of CBD oil, and it occurs more often when people are ill-rested and don’t sleep well. This happens because CBD may intensify the feeling of tiredness or weariness.

This symptom, however, shouldn’t be perceived as a regular one, because other patients have a completely opposite reaction – after taking cannabidiol, they feel stimulated, and motivated.

It’s worth looking into a proper sleep routine while using CBD oils, to reduce the chances of getting drowsy after taking them. Also, immediately after taking the supplement, you should avoid driving a car or other machines that require 100% of your concentration.

4. Reduced blood pressure

For some it’s a negative side effect, and for others it’s just one of cannabidiol’s numerous cardiovascular benefits. A reduced blood pressure (BP) is in fact the most important potential side effect of using CBD oil, as it correlates to all the other issues. As mentioned before it can cause drowsiness or dizziness for those not dealing with high BP issues.

People who take medications to lower their blood pressure should consult a doctor to make sure the cannabidiol doesn’t boost the effects of their other medicine. In reaction to an extra dose of CBD, the endocannabinoid system relaxes the organs so the blood starts flowing slower. However, this is not a dangerous side effect. It just might cause inconveniences.

5. Negative effects on other medication such as delaying or suppressing their effects

Hemp-derived CBD may interact with some medications because it suppresses the activity of certain liver enzymes, in particular cytochrome P450, which is responsible for the metabolization of nutrients. A person taking a lot of medicine, who decides to support their therapy with CBD oil to better their health and well-being, should consult a doctor.

A side effect you definitely won’t get

Although there are some people who find this to be a downside, most users are relieved to know that CBD oil won’t get you high. As the THC levels in CBD oil are barely traceable, the oil is non-psychoactive. The cannabinoids extracted from the hemp plant don’t have the same effects cannabis does. This means you can take the oil like any other supplement and function normally.
