The Artist: Kid Cudi
When He Quit Smoking: 2011
Why He Did It: Although he made his announcement on April Fool's Day last year, this most certainly was not a joke. Instead, Cudi announced he was quitting because he was "happy being a new me." On his Tumblr, he wrote: "Giva f--- who thinks of me different, you didnt care about me in the first place if you can be proud and happy for me for growing and starting a new chapter. Im not your puppet or your tap dancing drug addict here to be your miserable muse, i always made music for me to help myself find understanding. I have finally learned from the words in my songs. I love who loves me and who really cares about me."
