i didnt take up smoking until i was about 19, i was mainly only a social smoker but eventually it turned into smoking more frequantly, i was never a heavy smoker i was about a pack every 3 days which isnt too bad but its still smoking doesnt make a difference. but i decided to quit about 2 months ago and am doing quite good, i have had one smoke on 2 different occasions the last being a month ago, so im pretty sure i have quit for good. for anyone who has not being smoking for long, stop while you can do so easily, i am still only 21 so only 2 years since my first smoke, it was really easy for me to quit so i say to anyone who has not been smoking long that you might as well nip it in the bud and quit now because the more you prolong it the harder it will be.
