Cannabis is no longer the globally condemned drug that no one wants to do anything with. With the recent legalization of medical marijuana in Brazil, the world is gradually accepting that this plant and its by-products have a lot to offer humanity.

Likewise, more people are getting curious about CBD side effects, THC relevance and other related topics. It’s almost impossible not to have these conversations. Besides, not knowing these things puts you in a disadvantaged position with a high level of risk.I really don’t want you to feel anxious, and that’s why I put up this article. In this article, I’ll be answering the most salient questions regarding the risk factors and side effects of CBD. Let’s take a step further.

What Is CBD

CBD is an abbreviation for cannabidiol. It is one of the principal elements found in cannabis alongside others like THC. It’s found in large percentage in Indica variant of cannabis, and unlike THC, it’s also a legal substance in most parts of the world.

CBD is the element that gives you a relaxing effect and has been proven to be very resourceful in the treatment of several medical conditions.

What Are The Side Effects Of CBD?

Although CBD has lots of benefits, recent research across the globe has shown that there are numerous CBD negative side effects that loyal consumers should beware of. While some of them are quite minimalistic, others can be severe. These are the most common CBD side effects in keeping to proven research studies.

1. Low Blood Pressure

Regular CBD oil intake can lower your blood pressure, which explains why you often feel lightheaded. Although lowering one’s blood pressure is CBD’s working principle for treating people with diabetes and heart diseases, it also has dire effects on people without these ailments.

This was proven by a 2017 study. According to the study, a single dose of CBD is all that is needed to lower one’s blood pressure. Most times, it comes with symptoms like fatigue, blurred vision, fainting, and nausea.

If this applies to you, it’s recommended that you consult your doctor first before continuing with the CBD oil. You should also consider taking coffee too to boost your blood pressure.

2. Dizziness

Dizziness is one of the most common CBD negative side effects. It’s as a result of CBD’s relaxing effects that calms the nerve. To remedy the situation, you may opt for caffeinated drinks.

And drink a lot of water to avoid the dehydrating side effects of caffeine.

3. Dryness of Mouth

Consumption of cannabinoids, whether CBD, THC, or any of trace elements, often cause dryness of the mouth. At times, it would seem as though your mouth is stuffed with cotton balls. It’s pretty normal and not peculiar to you.

This happens because the human body has an endocannabinoid system that has its receptors in the salivary glands. When you take CBD, it reacts with the receptors which inhibit the secretion of saliva. Thus, leading to the dehydration of the mouth.

To get your salivary glands working at an optimal level again, you would have to take enough water during or after you had consumed the CBD. It’s as a result of dehydration. A sure way of relief is to consume a lot of water after consuming CBD.  to get you hydrated.

4. Diarrhea, Weight and Appetite Loss

This CBD side effect is according to a clinical study published in Cannabis and Cannabinoid Research Journal in 2017. The study was carried out on patients with epilepsy and psychotic disorders and how they react to CBD oil when treated with it.

According to the study, the test subjects experienced common side effects such as fatigue, diarrhea, and certain changes in their weight and/or appetite.

Despite these side effects, it was concluded that CBD oil has better side effects when compared to other drugs used in the treatment of epilepsy and psychotic disorders.

5. Side Effects on Patients With Movement Disorder

Another CBD side effects are evident in patients with pre-existing dystonic movement disorders. A study was published in the International Journal of Neuroscience in 2009, in which patients were treated with 100 – 600mg of CBD oil per day for six weeks.

They were treated with other standard medications and showed a considerable level of improvement. The ensuing CBD negative side effects were some of what we’ve discussed already.

But in addition to these, the patients also experienced “psychomotor slowing,” which means a slow down of thought process and physical movements. Patients that received as much as 300 mg/day had symptoms such as an increase in hypokinesia and resting tremor.

Previous research has also shown that patients with Parkinson’s Disease also experienced this same CBD side effects. Nonetheless, the research studies are not adequate to arrive at a conclusion. As such, more research needs to be done on the subject.

6. CBD Negative Side Effects On Pharmaceutical Drug

CBD also has tons of side effects on the liver when it reacts with certain pharmaceutical drugs. It has been revealed that CBD alters the activities of some enzymes in the liver, such as the cytochrome P450 enzyme system, which speeds up the metabolism of pharmaceutical drugs in the body.

This enzyme system contains up to 50 different enzymes that eliminate toxins in pharmaceutical drugs. Coincidentally, CBD needs these enzymes, too, for its metabolism. So, when taken in large quantities, CBD can totally neutralize the performance of the enzyme system.

Due to this setback, it’s advisable you consult with your doctor before you use CBD oil alongside any pharmaceutical drug.

7. Side Effects On FDA Approved Drugs For Epilepsy

In addition to CBD side effects on pharmaceutical drugs, CBD has adverse effects on certain drugs approved for the treatment of epilepsy. An example is Epidiolex, a CBD oral solution that was approved by the FDA for the treatment of two variants of epilepsy.

During a clinical trial of the drug, it was discovered that the CBD negative side effects are quite overwhelming. The effects include liver problems, gastrointestinal problems, reduced appetite & urination, depression, skin reactions, breathing problems, and infections. 


Although the benefits of the cannabinoid are mind-blowing, and pharmaceutical drugs side effect are much worse, you should always consult your doctor when starting with CBD.
