There are a number of possible side effects to using CBD oil, such as fatigue, dry mouth, lightheadedness, hypotension, and impaired motor functions. However, when used in moderate amounts, most people do not experience these side effects, and none of them are known for being fatal or particularly dangerous. More than 20,000 studies have been done in the past 15 years on cannabis, hemp, and cannabinoids, and the results have been overwhelmingly supportive of the therapeutic potential and viability of CBD oil. That being said, some people should be cautious before using this powerful oil.
A group of specialists at the National Cancer Institute reviewed some experiments rhesus monkeys and rodents whose results implied that CBD has the capacity to inhibit the division of cancerous cells (especially in types of leukemia and lymphoma), to lower the probability of affected tissue to spread to neighboring tissues, and to increase the effectiveness of macrophage cells to attack cancerous cells.
