Bullied because I don’t drink or smoke?

I have friends that like to smoke or drink socially, I do not just because drinking causes me extreme chest pain (not heart burn but actual chest pain) I don’t know why, I also just don’t like to smoke just cause.My friends will call me stupid or lame because I don’t want to. I don’t call them drunk or anything rude because they like to. I think it’s super rude they talk down to me because I don’t like to when I’m so nice about it to them and don’t care they do. Any tips on how to handle this? Also being an adult now I thought it’s a little immature they act like this because I have my own choices.
