CBD and THC: What You Need to Know

CBD oil is available in various forms – from tinctures and topicals to dog treats and bath bombs – and is widely regarded as being beneficial for various medical conditions. Many people, however, are apprehensive about CBD because of its connection to THC.

What Are Cannabinoids?

A cannabinoid is a chemical substance that is naturally produced in the human body as well as in the cannabis plant. While cannabinoids produced in the body are called endocannabinoids, cannabinoids produced by the plant are known as phytocannabinoids.

There are 480 different compounds present in the cannabis plant, but only 66 of them are cannabinoids.

Cannabinoids interact with specific cannabinoid receptors in the endocannabinoid system (ECS) and can trigger various physiological reactions, depending on the particular cannabinoid and receptor type.

There are two types of receptors in this system, known as CB1 and CB2 receptors. CB1 receptors are primarily in the central and peripheral nervous system, and CB2 reactors are mostly in the immune system.


Tetrahydrocannabinol (THC) and cannabidiol (CBD) are two of the best-known cannabinoids naturally produced by the plant. Both are used as active ingredients in products for human consumption, but there are significant differences between them.

CBD connects with CB2 receptors. As a result, it may reduce inflammation and, since CB2 receptors are not in the brain and spinal cords, the interaction between the CBD and receptors does not result in euphoria.

THC interacts with CB1 receptors and typically results in a “high” or feelings of euphoria.  

CBD and Marijuana

The average marijuana strain consists of 15%-20% THC and virtually no CBD. CBD oil may also contain small traces of THC, but for it to be legally sold in the United States, it can contain no more than 0.3%.

CBD oil is produced from two sources: Either hemp or cannabis. Hemp, which is grown for industrial purposes, contains almost no THC. Many products on the market are known as hemp-derived CBD.

CBD products derived from hemp are legal, as stated in the 2018 Farm Bill. CBD products derived from cannabis may or may not be legal, depending on where you live.

Cannabis breeders have created strains that are high in CBD and low in THC. These products are generally available in states where marijuana is legal, both recreationally and for medical use.

A number of companies, such as Royal CBD, offer full-spectrum CBD oil products online. The oil is extracted with all of the cannabinoids in it, but contains less than 0.3% THC, enough to not get you high, but to allow you experience the full plant benefits.
