I can't really tell you what's best because I don't know your dad for one and two, I don't know your dad's friend. But, from the way this friend sounds, he probably tokes up himself.

Just do what you feel is best and go with it. If you get caught, well, shit happens. But if you don't, then you just waisted an 8th for nothing. That's why it's best for you to decide based on your circumstances.
