> What test do you insist people pass before consuming alcohol or tobacco?

The same test, and lower the legal age too. Or given current realities, leave the age alone with no test, and with a test a lower age.

But as far as smoking goes you have to make sure to filter the smoke by some method and don't expose others.

> What about sugar?

Yes, sugar can be harmful, but it's hardly in the same class.
