Aside from these side effects, certain prescription medications can be habit-forming, leading to substance abuse issues. For these reasons, many people who have these disorders develop an interest in pursuing a more natural treatment approach, such as CBD oil. Even children with anxiety, insomnia, and post-traumatic stress disorder have been safely treated using CBD oil. CBD's effects are attributed to its link to serotonin, which is a type of neurotransmitter that is responsible for the regulation of social behavior and mood.
