In the time that I’ve treated thousands of patients with CBD Oil & Medical Marijuana since back in 2012, I have not had any patients report an allergic reaction to either CBD Oil or Medical Marijuana. That’s not to say it’s not possible. But, I would say the possibility is rare.
The other important factors to take into consideration is that there are a lot of other components in CBD Oil products & Medical Marijuana products. There could be pesticides, molds, etc. So, it’s quite possible to have an allergic reaction to these components, which makes it all the more important to ensure that the products that you purchase have been laboratory tested.
