This isn't 'targeting the homeless'. It's targeting smokers of all kinds, including those who use vaporizers. Note - I'm not a smoker of any kind. If this causes people who are doing nothing but cluttering up the mall to leave so they can get a fix then that's what happens. It's going to make the mall cleaner (far fewer cigarette butts) and maybe more people will use the pedestrian mall for, I don't know, walking?
