12. Mila Kunis
Mila Kunis just loves smoking – there are tons of photos on the internet that illustrates her addiction, but we are not here to judge. Ashton Kutcher, her husband, used to be a heavy smoker too, with up to 40 cigarettes a day, but he quit cold turkey together with his ex-wife Demi Moore. He said he was inspired by Allen Carr’s book, The Easy Way to Stop Smoking.
