idek why i'm posting so just keep scrollhing

so this girl i used to be friends with got into drugs (mostly weed) and drinking and cigs cuz of her sister. basically she change so we stopped being friends which is fine. we just started school today and she NO JOKE has a smokers voice and let me inform all of u that we r sophomore in highscool. idk why she would choose to smoke especially at this age. we weren't that close of friends but do u think she would listen if i talked to her about it? she has a whole group of friends that do this stuff so i kinda think i should just let her do her.
