The more friends a person is with when they are out drinking, the more they will drink themselves, a new study concludes.
The findings come from a study of almost 200 young adults in Switzerland, who participated in a survey on their smartphones. They were asked to check in hourly to report the number of drinks they had consumed, and the number of friends they were with. As the number of friends increased, so did the number of drinks a person consumed per hour, the study found. Men were more likely to drink more if they were in a bigger group, the researchers report in the journal Addiction.
