Pot protects against strokes... wow. There's a new one I haven't heard.
And the founding fathers were "probably stoned" while fighting the Revolutionary War.
Gotta love it.
Not that I'm for it, but it actually is scientifically proven to prevent prostate cancer, glaucoma, reduce blood-pressure, and several other things.
But more importantly, the ATF is over-stepping their boundaries on this one - they don't have the right to decree such stipulations on firearm sales and to be perfectly honest, they don't have the right to step on any of the State's rights to pass their own laws (in some states, Marijuana isn't illegal).
Think about it this way - what if the Fed government outlawed your favorite guilty pleasure (single-malt Scotch, certain cigars, whatever), but Oklahoma laughed at that and kept that same thing legal. Then the ATF steps in and tries to enforce that law regardless of what Oklahoma says and refuses to sell you a gun.
Its like the old Nazi saying - when they came for the (legal) pot-smoker's rights, I didn't say anything because I wasn't a pot-smoker...
