Interesting post. After 50 years in the practice of anesthesia, this is a question, without serious scientific research, that will probably not be answered. There are no panaceas! There are no specific drug recipes that are safe and effective for all individuals! If I were asked by a friend if CBD or THC would help them sleep, I would say try a small amount of each individually and see if it works for you. Everyone is different! Always remember, one person’s meat is another person’s poison!
