Smoking makes hangovers worse, new research says

Smoking can worsen symptoms of a hangover say researchers.

Researchers at Brown University found that those who smoked while drinking heavily felt much worse in the morning than those who did not smoke.

The study looked at 113 college students (naturally) and asked them to complete an online survey describing their smoking and drinking habits, said HealthDay.

They were also asked to describe their various hangovers over a six week period.

Researchers found that those who drank heavily (considered five to six beers within an hour) and also smoked that day had much worse hangovers than those who drank but did not smoke.

The more smoking the participants did that day the worse their hangover, said Time.

"At the same number of drinks, people who smoke more that day are more likely to have a hangover and have more intense hangovers," study author Damaris Rohsenow said, according to BBC.

"And smoking itself was linked to an increased risk of hangover compared with not smoking at all. That raises the likelihood that there is some direct effect of tobacco smoking on hangovers."

It is not completely clear why smoking worsens hangovers but its likely because both play with receptors in the brain.

Nicotine also has complex pharmacological effects on the nervous system, which might also play a role.

The study was published in the Journal of Studies on Alcohol and Drugs.
