I wonder if that war would have taken place if marijauna was readily available?
They had Morphine, don't know how controlled it was, as far as access. It's interesting that the first drug laws in this country came about, after the Civil War and it dealt with Morphine. It was probably in use, more then is known.
As Cole stated, hemp was around to make rope from and people probably had tried to burn it and discovered the effects upon them.
