ELI5: Why do people experience the urge to smoke cigarettes after they have consumed alcohol, yet don't experience these urges when they are sober?

Disinhibition is a well-known side effect if alcohol. This side effect is what makes nice people get into fights and for faithful people to cheat on their partner when drinking. Alcohol increases the likelihood for people to do things that they have a general threshold for avoiding.

Someone who never had smoked would likely never want to smoke without knowing what it was or being offered. But they'd possibly want to do something that they generally avoided but now were disinhibited from the alcohol. Similarly, someone who generally avoided smoking, but enjoyed doing so, would be more likely to want to smoke when drinking because it causes disinhibition and makes people do stupid shit for all of history.
