Experts actually have the opinion that the prohibition of drugs by the state is hinged more on speculation and fear mongering rather than empirical evidences. The fear that marijuana is destructive to health is in fact a myth according to Dr. Lester Grinspoon, professor emeritus at Harvard Medical School who reported that nobody died in the 10,000 years of known use of marijuana and yet, there were hundreds of thousands of people died from other medicines such as aspirin. In addition to its harmless nature to health, marijuana has a medical benefit to a lot of diseases. According to Dr. Tod Mikuriva , a former national administrator of the U.S. government's marijuana research programs, "After dealing with about 10,000 patents in the last 15 years, I'd say about 200 different medical conditions respond favorably to cannabis". Of those diseases that responded favorably to marijuana treatment was Alzheimer's disease, epilepsy, multiple sclerosis, glaucoma, arthritis, depression among the 200 diseases that it can possibly treat. The draconian measures imposed against the distribution and use of marijuana is not only pointless but economically costly as well. The most stringent law nor the broader use of the state’s police power have not deterred people from its used and this only manifests that the escalation of control and police enforcement is a wrong response and therefore pointless. It only pushed the industry into the black market which begets another set of problems.
