Laura said that for the average person, starting between 10 to 50 milligrams [of CBD] in a product is more than enough to feel a difference. She added that it's best to start with a smaller dose like 10 to 25 milligrams so you can learn how your body responds to a product. "If you have too much CBD for your system, you can experience some side effects," she added. "None of them are dangerous; there's no risk of overdosing with CBD, which is fantastic, but you can experience side effects such as drowsiness and dry mouth. [CBD] will also affect the way your body metabolizes medication if you have too much. That's why it's really important to start slowly."
