I knew it had to be a joke, because I used to chain-smoke, and only managed a little over 3 packs a day. 5 packs a day could definitely be accomplished, but it would have to done specifically to record high numbers.

Yeah, one of my best friends chain-smokes and I reckon 3 packs in 1 day would be unusual (though not necessarily unheard-of) even for him - usually it's more like just over 2 packs (45 - 50 cigarettes). He smokes several cigarettes per hour, at least.
He also usually wakes up during the middle of the night, has a smoke, and then falls asleep again. Not being able to sleep through the night without waking up for a smoke . . . now
that's nicotine addiction.
