The Potential Side Effects of CBD

The Potential Side Effects of CBD (3)

Although there is not enough research showing the true benefits of CBD, results from different studies have suggested that cannabidiol may be beneficial to the body and mind. However, some side effects can occur when taking CBD. In this article, we will be discussing them.

1. What is CBD?

Put simply, cannabidiol (abbreviated as CBD) is a cannabinoid or chemical compound that acts throughout the body, including certain parts of the brain. It is derived from the cannabis plant, but unlike its counterpart, tetrahydrocannabinol (THC), which is responsible for the so-called “entourage effect”, CBD found in the hemp plant is not intoxicating, and some believe it may have potential health and wellness benefits.

2. Common side effects of CBD

Yes, everyone’s body is different. What is good for one person may be bad for another. Nevertheless, CBD can help treat anxiety, epilepsy, pain, depression, sleep disorders, acne, etc. Every coin has two sides, however, and CBD also has side effects. Let’s take a closer look at them.

2.1 Drowsiness

Firstly, CBD may help deal with anxiety and pain, problems that can make it difficult to fall asleep. And secondly, CBD can interact directly with receptors in the brain that regulate the sleep-wake cycle in the body. So, does CBD make you sleepy during the day? Simply put, no, but at higher doses, CBD can affect people in different ways and cause drowsiness. If you experience this side effect, don’t drive or use heavy equipment – just reduce the dose you are taking. If you find CBD oil makes you sleepy, don’t take it earlier than an hour or two before bedtime. For many people, the most effective way to promote an overall sense of calm is to take CBD for sleep in the morning and evening.

2.2 Gastrointestinal problems

Gastrointestinal problems are one of the most common CBD side effects. They can include vomiting, diarrhoea, dizziness and other symptoms associated with digestive issues. But why does this happen? Well, some people simply don’t digest CBD oil properly. Also, side effects can often be due to the poor regulation of CBD products. There are no standards for dosage and safe measurement, so it’s quite possible for someone to ingest an amount that is much higher than what their body can handle. At this point, it will simply be flushed out.

2.3 Dry mouth

In 2006, a study in male rats found that cannabinoids can affect endocannabinoid receptors in the brain by suppressing CB1 and CB2, which control saliva production. This leads to a temporary decrease in saliva and a drier mouth. Fortunately, the solution is simple – drink more water than usual (for example, a glass of water after you have consumed CBD oil).

2.4 Interaction with other medications

Generally speaking, CBD can possibly interact with certain medications. In this regard, we recommend you consult with a doctor before taking CBD. Remember that certain medications may not work when taken with CBD. Furthermore, like grapefruit, CBD can affect enzymes that are responsible for and very important in the metabolism of drugs. That’s why before you start using cannabidiol, always check if any of the medications or supplements you’re taking have a special label with the “grapefruit” warning.

2.5 Nausea

According to research and consumer reviews, CBD oil drops can possibly cause stomach discomfort and nausea. Although CBD is specifically formulated to potentially address these symptoms, they can be caused by stomach sensitivity, taking CBD on an empty stomach (we recommend ingesting CBD between 30 minutes and an hour after meals), and taste or concentration can trigger nausea if a significant amount of CBD is consumed. In the event of stomach upset or nausea caused by CBD, it’s advisable to reduce the dose until you feel better or drink water immediately after taking the CBD oil to flush it out of your system.

2.6 Changes in mood or appetite

Cannabidiol can have various effects on mood and appetite. This can happen by reducing anxiety, causing people to eat more than usual or behave differently. CBD can also help to increase appetite, though mostly when taken in combination with THC products. We recommend keeping a record of your doses and being aware of how you behave, think, or feel when you are using CBD products.

3. Rare side effects of CBD

In this section, we will look at some of the less common side effects that you may experience when taking CBD.

3.1 Headaches and migraines

Actually, the likelihood of headaches as one of CBD oil side effects itself can be slim as CBD can be used to possibly treat headaches and migraines. On the other hand, they are experienced by people after using hemp CBD oil are most likely caused by the brand of oil used, the base oil of the tincture, solvents or poor-quality ingredients in general.

3.2 Increased effectiveness

CBD’s possible effectiveness can potentially increase the longer it is used. This means that a person may not need to take the same amount of CBD to achieve the same desired effect. It also means that after a few months of use, you should reduce the dosage to see whether you feel the same results.

3.3 Lower blood pressure

Furthermore, CBD may act as a blood thinner, possibly lowering blood pressure. This can pose a real risk to those taking anticoagulants. People who need to undergo surgery should stop taking CBD a week before the scheduled operation. This should also be discussed with your doctor if you are planning to have surgery.

There are several contraindications when you shouldn’t take CBD:

  • If you’re pregnant or trying to get pregnant, we recommend you avoid taking CBD.
  • A weakened immune system is a cue not to use CBD.
  • If you want to replace your current treatment, it is better not to consume CBD.

4. Final thoughts

CBD side effects are many and varied. So how can you avoid or minimise them? Our advice is to consult your doctor before consuming CBD, only choose reputable manufacturers, ask for third-party test results and not to overdose yourself. And remember, we are all different, and if CBD doesn’t cause any significant side effects for one person, it might for another. So exercise caution, ask professionals if you have any questions and only choose high-quality CBD products.
