Such in your opinion has a greater influence on teens decision to drink alcohol: the influence of family friends or advertisements why

If a teen's parents drink alcohol, they might decide to do so as well. This is because the teen can think that it's a normal adult hobby. If a teen's friends drink alcohol at a young age, the teen might do so as well, because they want to fit in, and not bullied/made fun of. An advertisement can encourage teen's to drink alcohol because the advertisement can say it will be a flavor the teen likes.
