This comment is recklessly ignorant: within 24 hours after your last cigarette, there is already a significant difference in blood pressure, and within a month the lungs have already begun to heal. Within a year the lungs have healed substantially. After a year, a person's risk of having coronary artery disease is cut in half. Smoking causes permanent damage, but spreading misinformation about "the damage already being done" is really unhelpful.
