Acetaldehyde (the first metabolite of ethanol, responsible for hangovers), is also implicated in increasing the effect of nicotine (among others, though i rate MAOIs as most important).

See for example: University of California - UC Newsroom | Nicotine's addictive hold increases when combined with other tobacco smoke chemicals, UCI study finds

"Although adolescent rats are more responsive to the nicotine-acetaldehyde mix than adult rats, the young rats were not more responsive to ....... than adults."

I want to be a lab rat.
