You better talk to your doctor about this because my doctor did prescribe me my CBD oil. But you never know what allergies you might have, and you better ask a professional for help first. Medical drugs are also not harmless if you take them in the wrong way or time.
Recently, I’ve found CBC isolate for sale at https://www.stateofmindlabs.com/store/CBC-Isolate-CBC-Distillate-p439053652 and use it now because it’s stronger than CBD oil or other regular stuff. Still, I did that knowing that I would probably have no side effects. I already knew my body was fine with taking bigger doses of drugs and had nothing to worry about.
