How do you tell if someone just started dipping?

Anonymous
He is one of my fiends and I feel very protective of him and so I think he just started dipping. How can you tell? I think he just started because his sister caught him with a dip can in his pocket and threatening to tell his mom. He said a friend dropped it at school and he was going to give it back now. We have been on break all week, and his friend who 'dropped it' lives right next to him. I'm not going to get him it trouble or anything, but I just want to know if he is doing it. I doubt he'll tell me the truth if I just go and ask him. I know that if someone dips then their teeth will start decaying and stuff like that happens in the mouth, but he's tall so I can't really tell that way. Plus I don't think he has been doing it long, so how do I tell if it has been only a week or month. He was really sweaty for no reason, does that have to do anything with it? (No reason as in no running, or any physical exercise, he was standing there and talking on the phone most of the time.)
