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).

Is CBD legal? Hemp-derived CBD products with less than 0.3% THC are legal federally but still illegal under some state laws. Cannabis-derived CBD products, on the other hand, are illegal federally but legal under some state laws. Check local legislation, especially when traveling. Also, keep in mind that the Food and Drug Administration (FDA) have not approved nonprescription CBD products, which 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.

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.
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.

- feeling drowsy
- gastrointestinal problems
- decreased appetite

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

CBD is a popular ingredient in consumer products. Current preliminary research suggests that CBD may prove beneficial for treating a range of conditions, including epilepsy, anxiety and other mood disorders, and some forms of chronic pain.
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.
