Does he know your sister died from drugs? If so, talk about it some more with him - how it killed her, how it messed up other people's lives etc. Talk about how you can't trust him because he lied to you and set reasonable consequences for the lying. But mostly, lay on the guilt so that he feels like a little **** for lying to you and risking his life doing something stupid.
