15 hours without nicotine (Edit: I'm pretty much a non-smoker now :p)

Switch to American Spirits.

I wouldn't recommend to use ecigs. Nicotine isn't the real problem when trying to quit (the molecule itself is out of the body after a couple of days, thus losing the need of more nicotine), but the gesture and that's the same as smoking a real cig. You may get hooked to ecigs for the next 10 years, i guess you couldn't really say that you quit.

Every time feel like a smoke, jack off instead, try it, just for shits n giggles?

Idiot!

See if you can find a sort of a support group of others who are trying to quit smoking. It helps if you have others to help you out. Tell your friends and family you are trying to quit. Just throwing out some ideas. I never smoked and don't plan to start anytime soon. But I know a person who was a drug addict for over 15 years. He finally managed to quit with the help of a support group. If he can do that, quitting smoking should be no problem :)

Death

E-cigarettes.

ps. My current mod: 1 2

film it.

Try eliminating your source of cigarettes. Destroy/sell your stash, be sure not to buy new ones. Stay away of your friends who smoke (if they do so) and you'll soon be free.

Find a substitute. There are two main methods of doing this, though first you must understand that there are two sides to your addiction: Firstly you are physically addicted to nicotine (you have little receptors in your body that need to be satisfied) and secondly there is your habit (bored? reach for a cig. Time to get up? wheres your pack. Stressed? go for a smoke etc). The habit can be retrained before you quit smoking, so then when you do actually quit you will only have to deal with the physical side of it (see method two below).

EITHER (for quitting immediately): find something to eat (you know, putting it in your mouth and all helps), something that you like and lasts about as long as a cigarette. Chewing gum lasts too long, gummibears don't, you can try various other confectionery things too. Now whenever you crave a cigarette, eat whatever you chose.

OR (for quitting in like 2 months): find something to eat just like in the option above, and eat a bit of every time you smoke. If you forget to too often it won't work, so take your chosen food with you everywhere you go (and store it with your ciggies too). Then, when your mind is really used to eating your special food every time you smoke, quit buying cigarettes. When you start craving one, you will find yourself automatically reaching for your special food, and while it won't stop the physical craving your mind will be satisfied that you are sticking to your habit and you will feel a little bit better. Nicotine patches work on the same principal, you kick the habit and then break the addiction at two different times.

Or just buy one of those ecigs, you get your nicotine with (supposedly) no health risks.

Or just don't bother quitting.

Well I smoked for some time and like ptsfthfll, one day I just told myself "No more cigarettes" and that was that. Instead of a cigarette, try getting some kind of placebo to fake the act of smoking (eg: pen, stylus, lollipop).

Try using cocaine.

I bought the e-cig just 3 days ago, and i'm not smoking a real sigarette from 3 days!
I use a juice with 9 mg of nicotine, but i'm not smoking the paper and the other shit inside a real sigarette.
Try it is worth it, and is really cheap! i bought 2 e-cigs 5 bottles of juice and 1 atomizer for just 67€

Just give up and accept your fate, you will never quit smoking.

nicotine patch works very well, you really want to stop you need stuff like this

I quit smoking a year and a half ago, and Im glad I did. Theres not one day that I wish i was still smoking. I occasionally miss the good feeling from smoking one, but in reality its not as good as I remember it. I did slip up after like 6 months, i had 2 cigerettes, I felt terrible, like I had failed, but I bit the bullet and continued on with quitting. The 2 cigarettes in reality did nothing, no worse then sitting next to smokers on a night out. You shouldnt give up, its a hard trip but after a couple of weeks it starts getting easier, within 3 months you barely think of them. It may pop into your mind for what feels like a long time, in reality its a matter of a minute or so. At this point even thinking of smoking doesnt interest me. I hope you can find the will power to continue quitting.

1 mounth without nicotine.(17 years of smoking)

I quitted smoking 2 years ago, i did not use those stupid e-cigaretes or nicotin patches.
Tell yourself you want to quit. If you feel like you want to smoke, just dont do it!
It will be a very hard time, but you just need to believe in yourself.

As others before me, I also suggest electronic cigarettes. In my case they are an alternative to tobacco. But I had no trouble switching and I don't cough anymore. If your goal is cessation I'd say try ecigs with 0mg nicotine liquid in a non-tobacco flavor. There are disposable ecigs that equal about a pack or two of usage. One of those may be good for starters.

Another thing: go to your doctor and tell him/her that you want your blood tested.
I did this and found out my blood was too thick, due to smoking. That didn't make me quit but I'm about to switch to e-cigs and then I'll just quit, eventually. Really, health is numero uno and money is just irrelevant. Who cares about money when they are bedsick/dead?

No joke, read this book:

The Easy Way to Stop Smoking by Allen Carr

Feel free to smoke while you read it, by the time you're done you'll be quit.
