So if a grandma committed murder she shouldn't go to jail because of the children? Are grandmothers exmpt from the law?
Millions of people over thousands of years have enjoyed the effects of marijuana. The damage has been far, far less than from alcohol; indeed, less than from aspirin
Sorry I don't think of becoming a burnout as a beneficial effect. I don't go for the marijuana is a "wonderweed" arguement.

That's your opinion, but I don't think that the US Constitution stands on the right to smoke dope anytime, anywhere.
The Constitution does not permit pot smoking. That would be because the Constitution was written to restrain the government. Anything not prohibited in the Constitution is allowed by definition (cf: Civics 101).
