CBD Side Effects, Are There Any?

CBD has seen extraordinary success in the wellness industry in recent years, but as beneficial as it has been reported to be, are there any drawbacks to using it?

First off, it should be noted that CBD has been found to be safe for human consumption. A study published by the National Center for Biotechnology Information states that “the safety profile [of CBD] is already established in a plethora of ways” and unlike THC, CBD is non-psychoactive and its side effects are minimal. Any side effects of CBD are extremely uncommon and many users claim to experience no side effects at all. Even in high doses, CBD is considered non-toxic for humans.

The quality of the CBD plays a large role in whether people experience adverse side effects. Pure CBD isolate like that used in Green Stem products is extracted from well-cultivated hemp plants using high-quality processes and therefore tends to be more effective and less likely to cause any unwanted side effects.

However, there are some side effects that are worth pointing out, though they are minor and very uncommon.

A dry sensation in the mouth is a common side effect of consuming CBD and other cannabinoids. This is mainly caused by anandamide, an endocannabinoid which blocks signals from the nervous system to produce saliva, leading to a dry mouth. Dry mouth can be worse if you choose to vape your CBD rather than ingesting it via other options such as oral drops or topical creams.

High doses of CBD oil can cause a slight drop in blood pressure, which can lead to feelings of dizziness and light-headedness. Lowering blood pressure can be useful in those who are at risk of heart disease and diabetes due to high blood pressure, but it may be a minor issue for those with normal blood pressure. However, this side effect does not last long and can be quickly resolved by drinking a caffeinated drink.

CBD can sometimes cause drowsiness, especially when taken in high quantities. People who respond to CBD in this way should avoid driving or operating heavy machinery. However, CBD does not typically induce feelings of drowsiness and in most cases is actually more likely to cause a state of wakefulness and increased energy. If CBD makes you feel drowsy, reducing the dosage can provide effective alleviation from the symptoms.

Research has also found that CBD has been proven effective in relieving the symptoms of insomnia. This is because the use of the CBD is reported to improve the brain’s ability to respond to stress, and a reduction in stress ultimately leads to a better ability to shut off, eliminate worry, and achieve a more restful night’s sleep.

There’s a small chance that CBD may interfere with pharmaceutical medication, so it’s good practice to consult with your doctor first before taking CBD. Although uncommon, high doses of CBD may inhibit the activity of P450 enzymes in the liver which break down the majority of pharmaceutical drugs for human consumption, and as such CBD may temporarily impact how drugs are broken down in the body. It’s worth pointing out that these effects are minor and usually subside quickly.

Although there are potential side effects associated with CBD, these effects are not hazardous and are largely uncommon.
