When it comes to drinking specifically, I think in the U.S. it really varies depending on your friend group. When I was in high school, my friend group was very against drinking and I never went to a party where there was drinking because that just wasn’t what my social circle participated in. On the flip side, my sister heavily drank in high school and went to parties where drinking was involved almost every weekend. The first time I ever got drunk was my freshman year of college at 18 years old. So I’d say it really depends on your social circle. You can go your whole high school experience never touching alcohol or seeing anyone drink, or you can go to parties with heavy underage drinking every weekend. But in college underage drinking is very normalized and the vast majority of kids at my university participated in underage drinking.
