Unsurprisingly, it wasn't by conventional means. It wasn't patches, and it wasn't hypnosis... Or was it?
Apparently Colin Farrell, who seems to have rid himself of all vices in the last few years, managed to quit smoking by - wait for it - writing a 'break up' letter with the ciggies and then burning it. We don't know whether he weeped while he sniffed the burning fumes, but either way it would've been a cathartic experience.
Now he didn't just write a letter to cigarettes, he penned a note to "the spirit of tobacco". Speaking with the September edition of Men's Health magazine, he said: "I wrote a breakup letter to the Spirit of Tobacco... I got a frying pan and tossed the letter with a load of tobacco, put some paraffin over it, and lit a match that sent a big, wallowing cloud up into the sky. Then I didn't have a cigarette for another two years."
OK, so it kind of worked. Two years is pretty amazing. And it won't cost you a penny - but it may cost you your eyebrows (don't try this at home, kids).
Speaking of kids, Colin's two boys James, 11, and Henry, 5 were invariably instrumental in his decision to choose a healthier path and not get consumed by Hollywood life: "You play the part and do interviews but don't overextend yourself or put on a mask or change your name... When you get home, the only thing that matters is your son is not eating his turkey sandwiches and he's not into avocado anymore, so you have to find something new that he'll eat for lunch."
