You need to clear the house (and car) of ashtrays, lighters and cigarettes. By making it harder for yourself to slip back into smoking you will increase your chances of success.

It can be tempting to kid yourself that it is a good idea to have a packet of cigarettes in the drawer to prove that you can avoid them, or ashtrays around the place to remind yourself how horrible they looked when they were full of ash… But the fact is that these things are reminders of smoking and opportunities to smoke.
