Alcohol is bad, but smoking is worse.
Smoking is both way more addictive and it is a bigger health risk.
It’s rare to be a moderate smoker, generally you either don’t smoke at all, or if you do you are a smoker, with numerous health risks.
With alcohol moderate use is the norm, and only excessive use will make you an alcoholic, resulting in numerous health risks.

AFAIK it has only lately become known that even moderate alcohol use is still a health risk. AFAIK mostly causing intestine cancer.
So instead we have campaigns warning against drinking to much, which was also how it started with cigarettes.
