Bon Jovi frontman Jon Bon Jovi has told Kerrang!'s sister magazine, Q, that he's given up smoking because he can't afford it."I swore off them before [our current] tour and I'm happy to say I haven't picked them up," he said. "I quit because I tried to get life insurance and the price [for a smoker] was so ridiculous it was enough to piss you off and just throw them in the garbage."Bon Jovi will take up a 12 night residency at London's O2 Arena next month.
