Cannabis is the umbrella term with Marijuana being on one side of the umbrella and Hemp being on the other.
Marijuana is high in THC (the psychoactive component) and low in CBD (non-psychoactive).
Hemp is high is CBD and low in THC.
Through the years farmers have genetically modified the cannabis plant to have more or less THC based on recreational or medicinal purposes. It is necessary to determine if your CBD oil is considered to be Marijuana-based CBD oil (possibly psychoactive) or Hemp-based CBD Oil (non-psychoactive. The Farm Bill that was passed in December of 2018 allowed for up to .3% of THC (trace amounts) to be legalized for medicinal purposes. When trace amounts of THC work together with CBD, it is called the Entourage Effect. This ultimately means an explosion of therapeutic benefits.
