Never heard of that: There is no reason to think it is connected. Unless you live in a place that has made use legal (or non-criminal), you may be feeling anxious and paranoid about it. While this should also not directly cause whiteheads, it can possibly be a psychosomatic symptom. Don't smoke if you feel worried. See if that clears it up. Otherwise it may just be simple pimples. Ask a dr. To check it out.
