A widespread belief that marijuana is an effective treatment for a wide assortment of ailments and a lack of scientific knowledge on its effects, has been somewhat exacerbated in recent times by a drive toward legalization.
Twenty-nine states plus the District of Columbia have now made marijuana available for medical — and, in some states, recreational — purposes.
What are the medical benefits of marijuana?
Over the years, research has yielded results to suggest that marijuana may be of benefit in the treatment of some conditions. These are listed below.
Alcoholism and drug addiction
Depression, post-traumatic stress disorder, and social anxiety
And lot more and they are facts not just rumors or word of mouth.
So if the governments and institutions can realize the true potential and just don't put it in the black list then may be we can use it as a benefit to mankind.
