I don’t want someone to snitch on me what to I do?

so I was talking with a friend in class and we were talking about weed we didn’t say the word out loud not that I can remember but I don’t want the people who heard to get me in trouble at school. My overthinking and anxiety is making me stressed about it. It happened a little while ago but still.
