The Hero book goes into this to a degree:<br/><br/>• Prostitution Is Legal (Sort Of):While Las Vegas legally  forbids  the  sale  of  sexual  acts,  prostitution  is legal in Nevada as a state unless city governments rule otherwise.  Effectively,  while  prostitution  is  illegal  in Las Vegas, it’s also commonplace and readily available.  Those communities that allow prostitution require sextrade workers to regularly obtain health screenings in an attempt to minimize the effects of sexually transmitted diseases. While the “Vegas whore” is a standard archetype for  the  city,  it’s  not  entirely  accurate.  (She’s  probably cleaner than those junkie-sluts in LA, anyway.)
