Messages for the individual smoker
• Those killed in middle age lose many years
• Stopping smoking works– Even in early middle age, those who stop (before they have
lung cancer or some other fatal disease) avoid most of their risk of being killed by tobacco
– Stopping before middle age works even better
www.deathsfromsmoking.net
• The risk is big: about half are killed
