I am 15 and I have a friend who is 15 and I texted her and said that I've drank some and its fun and that she should try it and kept asking her to drink with me and her dad was a cop which I didn't know so can I get in trouble with the law for that ?

Her dad may not like to hear that she was being coerced into drinking, but if she didn't drink with you and it was only texting, then I don't think you can get in trouble for that.

So you are scared this may be a problem and learn from it, okay.

Most likely not. There is no evidence that you were actually drinking.

And wait until you're legal - it's going to save you more problems than you know.
