Cannabidiol (CBD) is a chemical produced by the cannabis plant. It's the second more widely produced chemical by the plant after THC (tetrahydrocannabinol). CBD does not affect the brain the way THC induced psychoactive effects. One of the reasons CBD oil is growing in popularity is that it does not intoxicate users.

Research shows that CBD positively affects many patients who use it to reduce anxiety and depression. At the same time, it can increase anxiety among certain individuals. Generally, studies point to CBD delivering immediate results with minimal side effects. A study mentioned that CBD helps protect brain cells from harm.

From a biological perspective, CBD and THC activate the brain's endocannabinoid system. This system comprises brain and immune cell receptors that provide pain relief when CBD is ingested.

The most readily available CBD oil products in the United States are sold under the "broad-spectrum" and "full-spectrum" cannabis product type categories. The former indicates the product comes from the cannabis plant but does not contain THC. The latter means the product could have trace elements of THC. Many cannabis experts claim that full-spectrum is the better choice for relieving anxiety disorders.

The effects of CBD usually last 2-6 hours, but it depends on the dosage and the cannabis strain. The amount of time it stays in the body varies among individuals, so it's difficult to estimate. People taking a drug test don't have to worry about it appearing unless consumed with THC.

The side effects of CBD are relatively minor compared with other pain relief medications. Some people complain about dry mouth, drowsiness, and diarrhea. You may also feel appetite loss and fatigue. Since CBD is still in its early stages of research as a widely-accepted medication, there's a risk of a negative reaction for certain individuals using other medications, such as people who take blood thinners.
