A groundbreaking study of over 300,000 adults found that smoking just two to five cigarettes daily raises your risk of heart failure by 50% and death by 60%
They also found that dropping from 20 cigarettes to two per day did not produce a proportional drop in danger, concluding that there is no safe limit when it comes to smoking
Smoking damages nearly every system in your body, accelerating disease, weakening immunity, and increasing your risk of cancer, oral disease, inflammation, and chronic lung damage
