What Qualifies as a Strong CBD Oil

A strong CBD oil should have the highest concentration of CBD or potency in it. Most of the full spectrum CBD oils can consist of a minimum of up to 250mg of CBD per dropper or millilitre. This is considered the highest concentration of hemp extract, which can be used in making CBD oil. The amount of extract used by different CBD manufacturers varies, and this causes differences in the product’s strength.

Some CBD tinctures and broad spectrum have a higher potency because it is manufactured from a CBD isolate instead of the whole-plant extract. Such products consist of up to 300mg per millilitre. If you are looking for the strongest CBD oil, consider those with a concentration of 250mg per millilitre.

Benefits of High Strength CBD Oil

CBD is a compound in the cannabis plant that has wide-ranging health benefits. CBD oil helps with many medical conditions, including pain relief and nausea. High-strength CBD also helps in the treatment of epilepsy. Studies have shown that CBD oil can also help people who suffer from anxiety and depression.

Apart from the health benefits of high-strength CBD, users also get other economic benefits. The strong CBD is ideal for people who consume high doses of the product. Therefore, it allows people to consume fewer drops to meet the required dosage. This means that a bottle of CBD oil would last longer, and the user would save money in the long run. If a person buys less strong CBD, they will consume more to reach the required dosage, which would be costlier than strong CBD oil.

What Is the Highest Dosage of CBD Oil You Can Buy?

The highest dosage of CBD oil that a person can buy contains 7500mg per 30ml. However, this does not mean you should consume the highest dosage without a prescription. The highest dosage for consumption varies from one person to another. The proper dosage depends on the daily CBD milligrams an individual should consume.

If an individual takes more than 50mg daily, they should consider strong CBD oil because it allows you to buy a few bottles to meet the required dosage. If someone takes smaller dosages, they should consider low potency CBD.

The dosage also depends on whether you consumed the product before or not. If it is your first-time consuming CBD oil, consider low potency dosages. This would allow you to determine whether the product is a good fit or not. Consider switching to higher doses if it works well for you. However, ensure to buy the right potency depending on your dosage.

Is There a Way to Make CBD Oil Stronger?

Most of the CBD oil products in the market contain at least a potency of approximately 60mg per millilitre. However, this potency is not considered strong enough by people who consume higher doses. Strong CBD oil uses full spectrum extract. Therefore, the only way to make CBD stronger is by using more product concentration. 

Adding an extract of 200mg to 250mg per ml would make the oil stronger. If you are wondering how to make CBD oil stronger, it is achieved by using more concentrate and is best done by experts in a laboratory.

How Can Strong CBD Oil Make You Feel?

If you have never consumed strong CBD oil before, you can be assured that it will not make you feel different. THC and CBD are the two main cannabinoids found in cannabis plants and are likely to come across in the market. THC is extracted from marijuana plants, while CBD is found in industrial hemp strains. 

While THC gets you high due to the psychoactive properties of cannabinoids, CBD will not induce any psychoactive effects. This can be highly beneficial to those looking for natural pain and anxiety relief solutions. Therefore, you will not notice that you have consumed CBD oil as you would have with THC.

The Right Way to Take High-Strength CBD Oil

There is no specific and correct way to use high-strength CBD oil. What matters most is getting the CBD oil in the body and the proper doses. There are various methods to use CBD oil, and their choice depends on an individual’s preferences.

Process of Taking High CBD Oil

The process of getting CBD oil depends on an individual’s preference. CBD oil can be taken in four methods. They include inhalation, ingesting edibles, application to the skin and as a sublingual under the tongue.


This is considered the fastest way to get CBD oil into the body because it reaches the bloodstream quickly. People inhale CBD oil through vaping or smoking. One can smoke the CBD oil using an oil rig whereby they heat the chamber containing the oil. The oil is then placed in the heated chamber, and the individual inhales the resulting smoke. If you prefer to smoke pure CBD oil, it’s best to avoid rolling a marijuana joint because it would also contain THC, an illegal substance. 

The benefits of smoking CBD oil are that it gets into the body quickly, and one can easily control the amount inhaled. Vaping involves using a vaporizer pen to get CBD oil into the body. Vaping is an ideal option for people who wish to get CBD oil in the body fast and without facing the harshness of smoking to the throat.

Ingesting edibles 

This is the most common way of taking CBD oil. One can easily add edibles to their food or consume them without additives. One can also purchase CBD-infused foods. The only precaution is for people to be careful about the amount they consume. When consuming edibles, an individual is likely to overdose without their knowledge.

Skin application

Topical applications work best for pain relief and managing skin conditions. People also get CBD oil into their bodies through topical applications such as balms, ointments, or lotions. The best part about this method is that one does not require special tools to get the product into the body. Individuals only need to know the right dosage for themselves and apply it to their skin.

Under the tongue

People also take CBD oil by placing CBD oil tinctures under the tongue. These tinctures come in drops, similar to those placed in the eyes. When taking CBD using this method, a person should put a few drops under their tongue, hold for a few seconds then swallow. It is also among the fastest ways of getting CBD oil into the body.

Precautions for Taking High CBD Oil

While the consumption of CBD oil is considered safe, it has certain side effects that might not occur for everybody. Research indicates that oil could cause diarrhoea, dizziness, irritability, decreased appetite, and interactions with other drugs such as alcohol. These side effects may occur in rare situations, and therefore, it is recommended that people take the right dosage depending on their body requirements.

Things to Watch Out for When Buying Strong CBD Oil in the UK

The main thing to watch out for is the lab report. The lab reports provide an analysis of all the CBD oil components. It also outlines whether CBD oil is safe for consumption or not. For instance, it would show the percentage of pesticides in the compound and match it against the maximum percentage of pesticides safe for human consumption. The lab report will guide you in buying the best quality CBD oil.

Another thing to consider is the contents of the package. This package will be outlined in the package or the product description. It will ensure that you are buying the right concentrate. Given the various CBD oil products on the market, you can easily buy a product that doesn’t meet your desired dosage. Hence, you should check the concentrate, normally labelled in milligrams, to ensure it is in the right quantity.

Although several studies have shown CBD’s ability to help with several health concerns, it should be noted that we always encourage you to seek medical advice from licensed doctors before consuming CBD products. Also, while CBD vaping, in general, offers several health benefits, one should also note that vaping itself may be better for you than smoking CBD flowers but can still pose threats or dangers to one’s health.

For one, E-cigarette or vaping, Product use–Associated Lung Injury (EVALI), is a recently discovered disease that researchers have identified vitamin E acetate, a chemical added to some THC-containing vaping products, as the main—but possibly not the only—cause of the illness. Although none of our own products contains Vitamin E you should notify your doctor immediately if you feel any of the following symptoms. 

EVALI symptoms vary in time of apparition and severity, but they include nausea, vomiting, diarrhoea, abdominal pain, chest pain, cough, and shortness of breath. Chills, fever, fatigue, and recent weight loss are also some frequent symptoms.

Furthermore, keep in mind that CBD edibles such as gummies contain sugar in them. The correlation between sugar excess and Type II Diabetes continues to exist. Furthermore, in diabetic patients, consumption of marijuana edibles, especially the ones that are rich in sugar and THC can develop a serious condition called Diabetic Ketoacidosis. The role of CBD in the development of this condition is yet to be determined, but there may be a correlation. 

In addition, CBD edibles should always be stored in a safe place out of the reach of children, pets, or any person that doesn’t know about the CBD content of the product. The appearance and packaging accompanied by the habit of not reading the labels can lead to intoxication or the emergence of adverse events associated with a healthy dose or an overdose of CBD.
