CBD, or cannabidiol, is a chemical compound and one of several cannabinoids present in the Cannabis sativa plant. Many forms of CBD are available, including oils. Some of the most potent products can contain up to 7,500mg of CBD per 30 ml.

CBD has become a popular ingredient in oils, edibles, topicals, and even cosmetics. CBD does not cause the ‘high’ typically associated with cannabis use. The cause of the ‘high’ is another cannabinoid called tetrahydrocannabinol (THC).

People curious about CBD products and regular consumers alike may wonder about the most potent CBD oil available on the market.

In this article, we provide a list of high-potency CBD oils and other CBD products. We also discuss the potential benefits and risks of using strong CBD.

Is CBD legal?The 2018 Farm Bill removed hemp from the legal definition of marijuana in the Controlled Substances Act. This made some hemp-derived CBD products with less than 0.3 percent THC federally legal. However, CBD products containing more than 0.3 percent THC still fall under the legal definition of marijuana, making them federally illegal but legal under some state laws. Be sure to check state laws, especially when traveling. Also, keep in mind that the FDA has not approved nonprescription CBD products, and some products may be inaccurately labeled.

Below are some examples of high-strength CBD oils and tinctures. Oils and tinctures undergo slightly different extraction processes. Manufacturers produce CBD oils using carbon dioxide to extract the CBD, while tinctures undergo a process using alcohol.

While there is a wealth of research regarding the effects of cannabis and THC, there are very few high-quality human trials that investigate CBD alone.

However, new research comes out every day, which means our knowledge of CBD, and its effects are likely to expand significantly over the following decades.

It is difficult for experts to predict precisely how differences in strength impact CBD’s effectiveness.

Based on the findings reported in a 2020 review, CBD appears relatively safe at various doses. However, the authors did not pinpoint a specific dose or range of doses that they believed would benefit everyone.

Most of the studies included in this review evaluated daily doses of 300–600 mg of CBD, but a few studies reported using doses as high as 2,000 mg per day.

Everyone responds differently to CBD, so it best that people using CBD for this first time start at a lower dose.

Purchasing a product that contains a higher concentration of CBD may be more cost-effective for some people.

Someone who uses 300 mg of CBD for chronic pain or anxiety would use 12 full droppers of a 25 mg CBD oil. However, they could get a similar 300 mg dose from using only one and a half droppers of a 2,000 mg CBD oil.

While stronger products may provide more CBD per unit, they may lead to inaccurate dosing.

According to a 2018 report from the World Health Organization (WHO), CBD does not appear to cause any significant side effects even at doses above 150 mg per kilogram (kg) of body weight.

  • feeling drowsy
  • gastrointestinal problems
  • diarrhea
  • decreased appetite
  • mood changes, such as irritability
  • liver injury (certain drug interactions)
  • interactions with alcohol and other drugs

The FDA has approved only one CBD product called Epidiolex for severe forms of childhood epilepsy. The FDA does not regulate any other CBD products.

In a 2017 study, researchers evaluated the label accuracy of 54 CBD products from 31 companies. They tested a range of products, including oils, tinctures, and vaping formulas. Their third-party laboratory analysis showed that only 30.95% of products had accurately labeled CBD concentrations.

According to the authors, CBD oils had more accurate labeling than tinctures and vaping formulas.

However, most reputable CBD manufacturers will provide third-party lab results to their customers.

Consumers should always use caution when shopping for CBD, especially high potency products. High-potency CBD products can be inaccurately labeled. Some products may not even contain CBD.

Some CBD products may contain enough THC to produce a positive result in a drug test.

However, more high-quality, controlled trials are needed to verify the medical applications of CBD.

People who currently use CBD products but feel they may benefit from stronger alternatives can use this article for guidance. People who have never used CBD but are interested in giving it a try should start with a lower dose and gradually work their way up to stronger products.

People should also discuss CBD with a doctor or healthcare provider before taking it, as it might interact with other medications that a person is taking.
