A bit of help could be usefull...

[Ne0ster]

I've been a social smoker for a long time now.. Never felt any sort of craving or signs of addiction.. But some of my friends carried a pack of chewing gum with them. And they eat it when they have the urge to smoke. Apparently when u keep your mouth occupied you wont have the urge.. It would be good to tell your friends about your plan to quit. This way, they should stop offering cigarettes to you and should also stop you if they ever catch you smoking.
Hope this helps!
