should tobacco cigarettes become illegal?

A law that won't be obeyed is worse than no law at all.  I suspect that people will bootleg cigarettes if they ever become illegal.

Neither tobacco nor alcohol should be made illegal and alcohol should not be excessively taxed.

Your values are yours, if you don't like it, then don't drink it or smoke it. You don't need to impose your views on everyone else. 

I agree that tobacco should be banned.
