Left swipe dat.
Most millennials use Tinder, or at least know what it is (and if they say they don't, they're pretending). So when the anti-smoking collective Truth.com wanted its message to appeal to a younger audience, it used the popular dating app -- plus a bunch of Internet stars -- to highlight how smoking makes you less attractive in your online dating profile photos.
Truth partnered with YouTube and Vine stars, including Becky G, Fifth Harmony and King Bach, cramming as many pop culture references as it could into 150 seconds.
