"Have you ever..."
...two days into a quit decided that "just one" would get you through the day and then you'd REALLY quit. So you go buy a pack and smoke just one. Throw the rest of the pack out the window as you drive to work.
Some 24 hrs later you find yourself driving by the same spot you threw them out at, you stop, it's been drizzling all morning...you find the wet pack. You sort through them to find 2 that are still smokable... YES I DID THAT AND WORSE!
