I started smoking at 15....................JUST TO BE COOL!!! Made me sicker than a dog.....when i first started! Kept doing it.....became addicted and i smoked 18 yrs and just quit 4 months ago! I have to say, it wasnt easy!!!! I deal every day with this......BUT.......i feel soooooo much better....dont smell, no cough, have energy, awesome workouts, skin and hair look better. There are so many positives!!!!!! Smoking was starting to run me down! It's amazing how quick you can become addicted. I started with buying 1 and 2 at a time! Soon after a pack. I was up to a pack in a half a day! When you are a teenager..you dont think ahead about the damage you can do.....so this is wonderful that you are thinking about this! Believe me....when you hit your 30's, the damage you have done can really show!!! And 40's i cant even imagine. I am 33, and i actually still look young-----but----i do have damage to my face from smoking. Put it this way.....GUARANTEED......by the time i am 40-45, i will need to have botox, or some kind of treatment....UNLESS....if i continue to be a non smoker, the "smoker lines" will fade a little. Good Luck to you.....This is wonderful you are thinking about this now, as a teenager....it takes strength, and it sounds like you have it!!
