Cannabidiol (CBD) and tetrahydrocannabinol (THC) are both active compounds that derive from the Cannabis sativa plant. THC causes the “high” that people often associate with cannabis.
When making a CBD oil, manufacturers can isolate CBD from other cannabinoids and mix it with an oil. By doing this, they can make CBD oil that does not contain THC.
The products that we list below are of high quality, and their manufacturers can provide proof of independent, third-party testing. However, we advise that individuals do their own research before purchasing any CBD product.
It is important to note that none of the contributors to this article have tested these products. The review is research-based.
In this article, we describe CBD oil and the effects of CBD. We also provide a list of THC-free CBD oils that a person may wish to try.
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.
CBD oil is a product that is appearing more frequently in an array of products, including:
- face creams
To make CBD oil, a manufacturer takes the CBD compound from the Cannabis sativa plant. They then dilute it in a carrier oil, such as coconut oil, avocado oil, palm oil, or sunflower oil. This process creates a diluted form of CBD that manufacturers can then add to products.
The cannabis plant contains more than 100 cannabinoids. Depending on the type of CBD oil that a person decides to purchase, it may contain not only CBD but also other cannabinoids or cannabis plant compounds. These may include:
THC is the chemical that people often associate with the psychological effects, or high, of cannabis. Although some CBD oils may contain up to 0.3% THC, an amount this small is unlikely to affect a person. There are also many CBD products available that contain no trace of THC.
CBC is one of the most common cannabinoids in the Cannabis sativa plant. As with CBD, it does not cause a feeling of being high.
Terpenes are aromatic oils that provide the Cannabis sativa plant with its smell and taste. These compounds are abundant in the cannabis plant, but they are also present in many other plants, including fruits and herbs.
CBG is another one of the more common cannabinoids in the Cannabis sativa plant. All cannabinoids start off as CBG and later synthesize into different types of cannabinoids.
CBN is a similar cannabinoid to CBD. However, CBN forms as a result of an oxidization process in the plant, in which exposure to heat and light turns THC into CBN. Much like CBD, CBN is unlikely to make a person feel high.
There are three different types of CBD oils, and the key distinction between them is that they contain different amounts of cannabinoids. The types are:
- Full spectrum: This term means that the oil contains all the cannabinoids that occur naturally in the cannabis plant, including trace amounts of THC.
- Broad spectrum: This type of CBD oil will typically contain all the cannabinoids in the plant except THC. However, some products may contain trace quantities of THC.
- Isolated CBD: Of the three types of oils, isolated CBD is the purest. Products that contain isolated CBD contain no other cannabinoids.
The body of research specifically exploring CBD oil is still small. However, scientific research on the effects of CBD can suggest what potential benefits the oil might offer.
Research looking at CBD has found that it might have the following benefits:
- Anti-inflammatory: Research in rats highlights that CBD can reduce inflammation associated with arthritis.
- Reducing anxiety: CBD may help decrease symptoms of anxiety.
- Sleeping: A 2017 review concludes that medium and high doses of CBD can have a sedating effect, potentially helping people who struggle to fall asleep.
- Reducing acne: CBD may suppress the growth of sebocytes — cells that secrete sebum, which can contribute to the development of pimples.
- Pain: Older research in the Journal of Opioid Management suggests that cannabinoids have an analgesic potential, meaning that they may be useful in treating pain.
Even though scientific research exploring the effects of CBD in humans is increasing, much more is still necessary, as undiscovered short-term and long-term side effects may exist.
In rare cases, CBD oil may cause an allergic reaction. If a person starts using CBD oil and experiences the following symptoms, they should discontinue their use of the product and seek emergency medical attention:
- swelling of the throat, lips, or mouth
- itching in the mouth
- difficulty swallowing or breathing
Many CBD oils are available on the market. Below are three that are of high quality and contain no THC.
Sunday Scaries CBD Oil Tincture with Vitamins
Companies may use the terms tinctures and oils interchangeably. However, while both products fall into the oils category, they differ in the way manufacturers extract the CBD.
To create a tincture, the extraction of the CBD involves alcohol or another liquid solvent. Conversely, the production of CBD oils uses a gas, such as carbon dioxide, to extract the CBD.
The Sunday Scaries CBD Oil Tincture with Vitamins contains 30 milligrams (mg) of CBD per dropper. The manufacturers claim that it can help a person relax before bedtime.
CBDistillery THC-free Pure CBD Oil Tincture — 500 mg
This product comes in a variety of strengths, from 8 mg up to 167 mg. A person may wish to seek advice from a healthcare professional on what dosage may be best.
The company suggest that a person take 1 milliliter orally and hold it under their tongue for 15–20 seconds before swallowing.
The product only contains two ingredients: fractionated coconut oil (MCT) and cannabidiol (CBD) from hemp extract.
Penguin Broad-Spectrum CBD Oil — Strawberry — 1,000 mg
This broad-spectrum product comes in three different strengths.
The manufacturers recommend using the product once or twice a day. They suggest placing one full dose under the tongue, then waiting 60–90 seconds before swallowing.
Alternatively, a person can mix the product with food or drink.
If a person does not usually like the taste of CBD oil, this may be a good product for them, as it comes in strawberry flavor.
CBD oil may offer a range of benefits, including improving sleep, reducing acne, and relieving pain. For personal reasons, a person may not wish to use a CBD oil that contains THC.
Manufacturers of CBD oil can isolate CBD from THC to create a THC-free product. They may also choose to isolate CBD from the other cannabinoids in the cannabis plant to produce a product containing only CBD.
