AITA

My whole life, 18m, my family has been smokers ( cancer sticks and the devils lettuce ) and I cannot stand anything that involves smoking. I recently bought my first car (2025 accord) and told my family there is no smoking allowed. All of my friends vape and I don't want anyone vaping in my car either. I know it doesn't leave any smell, or make the ceiling yellow like cancer sticks , but I just don't like it. How can I tell my 15+ friends, that I don't want them vaping in my car without giving them a reason? Since there honestly is no valid reason
