What is the name of your state (only U.S. law)? Arizona. My buddy is really into vaping, and he wants to fly with his Vapor Pen. I am on probation and both of us are under 18, making it illegal to possess products of this nature. I don't want to have any problems with this that could violate my probation since we are flying together. When TSA finds these in his bag, is it likely that they will ID him or me to find out if we are of age? There is no laws against flying with products like these. I'm strictly worried about the underage factor.
