Humans have been using medical cannabis to treat a vast array of ailments for thousands of years. Physicians in the United States used it as far back as the 1800s, at which time they were allowed to operate independently, free from government regulation. At that time, cannabis was one of their most commonly used medicines.
Even the pharmaceutical industry utilized cannabis medicinally. By 1850, many pharmaceutical companies were using cannabis for a large variety of illnesses, including cholera, rabies, alcoholism, opiate addiction, typhus, leprosy, insanity, tonsillitis, excessive menstrual bleeding and many others.
But once drugs like aspirin and morphine proved to be more lucrative, the demonization of cannabis soon followed. After the U.S. Food and Drugs Act was passed in 1906, access to cannabis slowly began slipping away.
