Am I controlling?

I suggest my girlfriend to build boundaries and keep some distance with some of her friends after she told me that 2 of her friends were trying to shove cigarettes into her mouth. Am i being too controlling? I love her and i dont want bad things to happen to her 🫩 (we are both 17, 18 in a few months)

She said she have enough willpower to not be influenced by these people, and she said they aren’t her type of people anyways and she's avoiding hanging out with them. I just had to give her a suggestion and she thinks on her own👍
