This is the very first article I've read with actual NUMBERS highlighting a person's risk if they 'socially smoke' or lightly smoke (may not on a daily basis: less than 5 cigarettes on the days they do smoke. anywhere from 1-39 cigarettes/week).
A person may socially smoke a few cigarettes a night on the weekend when they are drinking or at a party.
Results of this study:
Women (35-49 years old) who smoke 1-4 cigarettes a day have 5 times the risk of developing lung cancer and men have 3 times the risk as non-smokers.
Light Smokers have a lower-quality of life than nonsmokers (general health, mental health, physically)
Women 'light smokers' have a shorten life span of 4-6 years!!!
Light smoking is a 100% turn-off for a man or woman! (ok, i just added that).
Bottom Line:
Even light smoking comes with deadly, and life-debilitating risks. Any time your friend tells you "i just have a few when I go out on the weekends" remind them of this!!
