The facts are in: marijuana is less risky to health than alcohol or tobacco.
I have never used marijuana, and have no real plans to do so, at least not until it is legalized, and maybe not then. I have nothing against people who use it, except that they are breaking the law. However, I very much disagree with that law, and it should be abolished. We should ban tobacco instead if we must ban something.
That is all.
