ehh wrong.
it's never been considered to be legalized because everyone always considered cannabis to be a hardcore drug. Or a "gateway drug" (..pfft please.)
but yeah, that's the real reason why its never been on a ballot before.
People are starting to actually realize that smoking cannabis, is actually less harmful on your health as nicotine from tobacco. That's an actual fact.. its been proven by scientists in an actual lab.
So, I have to disagree with the idea of cannabis NEVER being legalized. It'll happen.. as its not a matter of "if", but a matter of "when".
peace.
