What is CBD Oil

The concentrated liquid extracted from the marijuana plant is referred to as cannabis oil. Just like any other liquid extracts from other plants, cannabis oil also differs in chemicals present. The chemicals vary depending on the mode of extraction used and chemicals present in a specific strain of marijuana.

While the marijuana plant has thousands of compounds, one which is famously recognized is the cannabinoid. Cannabinoids come in various forms; nonetheless, there are two that are so famous, and these include CBD (cannabidiol) and THC (tetrahydrocannabinol).

THC is a psychoactive compound in weed and is the one responsible for getting individuals high. CBD, on the other hand, does not cause a high effect when consumed. It is, therefore, what people who want to avoid getting high but want to benefit from the health benefits of the CBD. CBD products that do not have THC in them do not fall under the US Controlled Substances Act of the US Drug Enforcement Agency. This, therefore, means that CBD oils are legal to sell and consume since they do not contain traces of THC. This is why they have increasingly become common these days. Forbes, in 2016, reported that CBD products were expected to stand at $2.2 billion industry by the year 2020.

How are CBD Oils Consumed?

There are up to 4 ways of consuming CBD oil. Here they are.

Smoking or Vaping Marijuana

Inhaling it is thought to be one of the fastest ways to feel CBD effects because it goes straight to your lungs and the bloodstream. CBD concentrates can be smoked using an oil rig that is similar to a water pipe and works by heating the chamber where CBD oil is placed and then put the oil into the nail with a dabber.


It can be purchased in bottles that look much similar to eye drops and take your CBD oil under your tongue. You only apply a few drops under your tongue and hold them for 30 minutes. The method is discrete and effective. It is easy to use and easy to control dosage.

Topical Application

You also can place it under your skin in the form of ointment or balm. You do not require any additional tools, and the method is the easiest once you figure out your dosage. The method is excellent for migraines, sore muscles, skin acne, and more.


CBD oils can be added to your food. Today, there are a lot of CBD edibles such as weed lollipops or CBD gummy bears, etc. They won’t cause any highness. While you can buy them, you also can make some at home eg, weed brownies even without prior baking experience.

Side Effects Of CBD Oils



While the oils do not induce a feeling of drowsiness to individuals, its effects can vary from an individual to another. The oil typically is having a wake-inducing impact and makes one more energetic and alert. In others, though, it can cause the opposite. Therefore in high doses, some people experience this side effect. If you are one of them, then you should refrain from operating machinery for your safety reasons. Also, if you fall among this category, it is vital to check your dosage and only consume the right amount.

A drop in blood pressure

The drop in blood pressure causes people to experience lightheadedness. Research shows that CBD oils can help people suffering from diabetes and heart diseases since it lowers their blood pressure. Nonetheless, it can also have an adverse effect on people with the right blood pressure, especially when they consume larger doses. Therefore if you suffer low blood pressure or you are taking medicines for it, you should avoid taking CBD oils or CBD products. When this effect happens to you, drink coffee to help with lightheadedness.

Diarrhea, change in appetite and weight

In a 2017 study that was carried out on people with psychotic disorders and epilepsy on cannabinoid, it was seen that they experienced near the same side effects; change in weight and appetite, diarrhea, and the feeling of tiredness. The research concluded that in comparison with other drugs used in the treatment of these diseases, CBD had a better side effect profile.

Interaction with other pharmaceutical drugs


If you are taking any pharmaceutical medications for a pre-existing medical condition, you need to be extra careful about the effects of CBD on drug metabolism within your liver. Research shows that CBD impedes the activities of some enzymes found in the liver, like particularly CYP3A4. CYP3A4 is responsible for metabolizing pharmaceutical drugs for human consumption.

The P450 enzyme system has over 50 enzymes that process and get rid of toxins, and when you take CBD oils in large doses, it neutralizes the activities of the P450 enzymes. Its because the CBD oil needs the same enzymes to get metabolized.

Causes nausea and a general feeling of sickness

One can argue that nausea and gastrointestinal issues are not severe health complications. These can be experienced after consuming CBD oils. Nausea and gastrointestinal issues can lead to diarrhea, vomiting, dizziness, and even many other symptoms that are associated with a digestive problem. As said earlier, CBD oils have different effects on different people, and, indeed, some people do not digest CBD oil well. The same is also not uncommon with supplements and oils.

CBD oil is an unregulated supplement, which means that there are no standards for safe measurement and dosage. Therefore, cases of getting far too much dosage than you need are common. This, therefore, calls for your body to flush what it does not need in a very unpleasant way.

Liver damage

Does it cause liver damage? As hard as it is to imagine that CBD oil damages the liver, a study conducted by the University of Arkansas suggest so. The research looked at the possible side effects that CBD has on the mice’s liver. It was seen that CBD damaged up to 75% of the mice used in the research. Many other herbal supplements can cause side effects like liver damage. Since the FDA does not regulate CBD oils, one should take great caution when consuming them, especially in large doses.

Dryness of the mouth

When consuming CBD oils or any other cannabinoids, you will most probably suffer mouth dryness. You will feel as though your mouth is filled with cotton balls. To overcome this, you need to drink plenty of fluids, including water, during, and after consuming CBD oils and products.

Can increase the permeability of the placenta thus putting at risk a pregnancy

If you are expectant or a breastfeeding mother, you are used to seeing the safety warning on most products you purchase. While it is essential for breastfeeding and pregnant women to use CBD, most researchers also tend to avoid this category of individuals in their research. This is aimed at preventing adverse effects to either the mother or the fetus.  CBD could increase the permeability of the placenta barrier. This is according to a study conducted by the American Academy of Pediatrics. The result would put the pregnancy at risk.

On children

Medical CBD and Epidiolex are approved to treat some cases of severe pediatric epilepsy in many states in the US. However, the safety of CBD in kids has not yet been widely tested. Therefore caution should be taken when using it to treat these diseases. As a rule of thumb, you need to speak t6o your pediatrician before you can administer CBD regimen to your kid.

Bottom line

It is no doubt that CBD oils play a significant role in easing several health issues such as depression, anxiety, heart disease, acne, and much more. It is also recommended for people with cancer to relieve the pain as well as the symptoms. Many other studies are ongoing. There is much more to learn. And as it has been touted to be beneficial, understanding its side effects is invaluable as it will enable you to draw the line on how to consume it and what is your right dosage, among other things.
