We rightly ban "speeding" and other reckless behavior, none of which is mentioned in the Constitution.

We are thinking human beings with the Constitution in our hands. If we really are thinking, we'll severely curtail or ban destructive substances, especially when we have ample evidence of their destructive natures.

If we really are thinking, we'll severely curtail or ban destructive substances, especially when we have ample evidence of their destructive natures.

Like alcohol.

And tobacco.

And sugary drinks.

And bacon.
