Hemp doesn't come from the same plant as marijuana.
The hemp plant is a similar type plant in the same family of plants, but they are different. You can't get high from hemp no matter how much you smoke of it.
I support the commercial use of hemp. It is a great renewable plant and can be used for many purposes.
I suspect many of the stoner and hippy types, don't even know what they are talking about.
However, I do not support the legalization of pot under any circumstances. It is not a harmless and benign drug as it is often portrayed in popular culture.
