Instead, CBD is thought to influence other receptors, including opioid receptors that regulate pain and glycine receptors involved in the regulation of the “feel-good” hormone and neurotransmitter serotonin.
Part of this response could be explained by the way that CBD acts in the brain. In low doses, CBD may act as an agonist to several receptor sites, meaning it acts similarly to surrounding molecules that normally bind to the receptor, enhancing the signalling of those receptor sites. At higher doses, however, too much activity at the receptor site can lead to an opposite effect, negating the beneficial effects of CBD.
There have also been suggestions that CBD may aid in the treatment of cannabis and nicotine addiction. Further research is needed.
CBD oil is an extract of Cannabis indica or Cannabis sativa—the same plants that, when dried, make marijuana. CBD oil is believed by some to treat pain, reduce anxiety, and stimulate appetite in the same way that marijuana does, but without its psychoactive effects. CBD has also shown promise in treating certain types of seizures.
CBD oil may reduce the risk of heart disease by alleviating hypertension (high blood pressure) in certain people, suggests a 2017 study in JCI Insight.
Although hemp and marijuana come from the same species of cannabis plant, hemp has little to no THC. This means that consuming hemp is legal in the U.S. and will not cause you to become intoxicated or impaired.

Potential Health Benefits of Hemp Oil
In general, hemp seed oil is safe to ingest or use topically, but there are a few things to note if you decide to start taking hemp oil. Pay attention to the following potential risks of hemp oil:
Over time, excess inflammation in your body can contribute to a variety of diseases including heart disease, diabetes, cancer, and asthma. It has been suggested that gamma linolenic acid, an omega-6 fatty acid found in hemp, acts as an anti-inflammatory. Studies have also linked the omega-3 fatty acids in hemp with reductions in inflammation.
