Average cigarette smoking reduced the total life expectancy by 6.8 years, whereas heavy cigarette smoking reduced the total life expectancy by 8.8 years. The number of total life-years lost due to cigar or pipe smoking was 4.7 years. Moreover, cigarette smoking reduced the number of disease-free life-years by 5.8 years, and cigar or pipe smoking by 5.2 years. Stopping cigarette smoking at age 40 increased the life expectancy by 4.6 years, while the number of disease-free life-years was increased by 3.0 years.
Depende del tiempo que lleves fumando, de cuanto fumes y de cuantos anios lleves sin fumar.
In developed countries as a whole, tobacco is responsible for 24% of all male deaths and 7% of all female deaths: these figures rise to over 40% in men in some countries of central and eastern Europe and to 17% in women in the United States. The average loss of life of smokers is 8 years. Among United Kingdom doctors followed for 40 years, overall death rates in middle age were about three times higher among doctors who smoked cigarettes as among doctors who had never smoked regularly. About half of all regular cigarette smokers will eventually be killed by their habit.
Tobacco now causes one-third of all male deaths in middle age (plus one fifth in old age). Tobacco is a cause of about half of all male cancer deaths in middle age (plus one-third in old age). Of those who start smoking in their teenage years and keep on smoking, about half will be killed by tobacco. Half of these deaths will be in middle age (35-69) and each will lose an average of 20-25 years of non-smoker life expectancy.
Los que fuman desde la adolescencia tienen un 25% de probabilidad de morir entre los 35 y los 69 por causas relacionadas con el tabaco y otro 25% de hacerlo despues! Creo que es basante significativo, ya que no hemos hablado de las otras multiples enfermedades no mortales que tambien causa el tabaco.
Every cigarette a man smokes reduces his life by 11 minutes. Each carton of cigarettes thus represents a day and a half of lost life. Every year a man smokes a pack a day, he shortens his life by almost 2 months.

There are some 1.1 billion people who smoke on our planet earth. Just less than one-third of all adults in the world smoke regularly. Tobacco deaths will not only occur in old age but will start when smokers are about age 35. Half of those who die from smoking-related causes will die in middle age, each losing about 25 years of life expectancy. More than 95% of the tobacco consumed is in the form of cigarettes. About half of all smokers who undergo lung cancer take up smoking again.

Y ojo que yo he sido fumador, bastante poco y de forma intermitente, 6 meses si, 6 meses no, habitualmente mucho los fines de semana paquete o mas por dia de juerga y durante la semana un paquete para toda la semana o menos, en general se puede decir que he fumado durante algo mas de una decada de forma intermitente (efectivos quiza 3 años en total a una media de media cajetilla al dia) y tampoco demasiado dejandolo por completo a los 35, pero antes de los 35, por ejemplo entre los 30 y los 35 fume solo unos 3 o 4 meses sueltos solo socialmente y cosas asi... Yo siempre he tenido facilidad para dejarlo y luego sobre todo por ser muy juerguista para volver, todavia ahora si me tomo unas cuantas copas me fumo un par, lo que pasa es que eso ya lo hago tres o cuatro veces al año.
