Not so much "chalk and cheese" but "feather and revolver"
It's merely an illustration that the absolute language used to proclaim that there are no social issues related to them is not correct.
>"No county, municipality or other political subdivision may adopt or enforce any local law, ordinance, resolution or rule having the force of law that includes being a common drunkard or being found in an intoxicated condition as one of the elements of the offense giving rise to criminal or civil penalty or sanctions..."
And in fact they specifically make it illegal to do the thing you suggest, and use other laws as a backdoor against public intox:
>"No county, municipality or other political subdivision may interpret or apply any law of general application to circumvent the provision of subsection A."
(This leaves ability to pass a law at state level, but state has no public drunk law)
But my point still stands - there are social negatives that we pass laws around consumption of various drugs (including alcohol), and that they are very similar in most states (AZ might not have a public drunkeness law, but still has plenty about other stuff like DUI, public consumption, age limits, licensing, open container law, etc).
I wouldn't go that far. Any substance that alters perception, inhibition, etc has the potential for some social impact. For example, public drunkenness, DUI, liquor license etc were created because intoxicated people caused some sort of problem and laws were created around that. While these were created for alcohol, it's likely similar laws would be created for other substances.
