There’s still a lot of unknown territory, but early evidence for CBD’s efficacy is more than enough to justify further large-scale clinical studies — some of which are already in the works. These studies also point to the variety of effective ways to take CBD. This is an important point to keep in mind if you find yourself shopping for CBD products and wondering if the best CBD for pain is a topical, a tincture, or a vape product.
Dry Mouth: As is the case with many other hemp- and marijuana-based products, CBD oil often leads to a condition known as dry mouth (or cottonmouth). This is likely due to cannabinoids altering receptors in the lower jaw that trigger salivation. In most cases, mild discomfort and stronger-than-average thirst are the only issues associated with dry mouth.
