A better question is who are you to force your personal pleasure on anyone else?  There are a couple of things wrong with your argument.  One of them is that no one has the moral right to harm others just to get their own kicks; a truth that applies to everything from smoking/vaping marijuana where people with allergic reactions will be exposed to it just by the fact of needing to breath through harm caused to minors around the users to victims of accidents involving someone who is high.  Another thing wrong with your argument is the use of fallacies: moral equivalency ("this is safer than that" does not justify using "this") and appeal to popularity ("everyone does it" obvious).

it does not affect the way i work in any way i just pay attention in class all the time it does not matter what they are wearing
