As for coming to a conclusion on these matter, the fact is there is none yet. The answer to these problems usually lay in the land of compromise were each side has given and taken just the right amount so that they feel they ve ended up somewhere near where they started. The question is not whether marijuana works as a medication. That has been proven already.
Every scientific discovery is born into a vast sea of society and politics.
In our current society, marijuana has become the devil himself. For him to find entrance into our society as a peer requires him not just to be a fine upstanding citizen but a veritable saint. From the research I have seen, I would have to conclude that the answer is no. Presently, there are many other drug regiments that can do just as good of a job if not better than marijuana. Not only can they do the job they do it without the social and legal stigmata associated with being pothead.
