Heavy smoking and drinking For a 2016 study, researchers recruited more than 200 heterosexual young women in Belgium to look at photos and bios of young men. Results showed that men whose bios indicated they smoked frequently were considered less attractive than nonsmokers and occasional smokers — especially if the men were being considered for a long-term relationship As for drinking, occasional drinkers were rated more attractive than nondrinkers and frequent drinkers when they were being considered for both short- and long-term relationships.
