Need I say more… Cigarette smoking is the lead cause of preventable deaths a US study showed. Quitting smoking is difficult, but it’s worth it to save money, time, and potentially your life. Smoking is most commonly associated with cancer, but it’s a big player in other chronic illnesses too. But there’s good news! The CDC advocates that those who quit smoking before 40 will reduce the risk of smoking-related illnesses by 90%, but whenever you go through the trial of quitting cigarettes there will be a positive impact on your life expectancy.
