The oral use of cannabis and CBD for anxiety appears in a Vedic text dated around 2000 BCE, and it is one of the most common uses of the plant across various cultures. While THC can increase anxiety in some patients, it lowers it in others. However, CBD effects have been shown to consistently reduce anxiety when present in higher concentrations in the cannabis plant. On its own, CBD has been shown in a number of animal and human studies to lessen anxiety. The stress-reducing effect appears to be related to activity in both the limbic and paralimbic brain areas.
This lack of transparency can be boiled down to a couple reasons that are all intertwined. First, what’s holding everything back is the taboo against cannabis (“marijuana”) that continues to exist in our society. We still hear amazingly exaggerated horror stories of what marijuana can do to us. The Reefer Madness that started back in the 1930s hasn’t gone away. This recent video of Gary Johnson faking a heart attack because of a ludicrous claim against marijuana is just one example.
