Dub Pistols CBD Oil works with the brain receptor called the CB1 receptor. Receptors are the tiny proteins that are attached to your cells that receive chemical signals from different stimuli and help your cells respond. The exact way in which the CBD affects CB1 is not fully understood but it is thought that it alters the serotonin signals in the brain. Serotonin is one of the body’s chemicals and plays a vital role in mental health. Low levels of serotonin are a common sign of depression thus the absence of enough serotonin, which can also aid in the process of anxiety in some people.
