I know, a provocative thread title, but one I assure you is appropriate to Lost.

So, have I missed it or does no one smoke on the Island? If so, they must have used up their supplies, because i haven't seen anyone, even the Others.

We know they drink, because of the mini-bottles and various bottles that sprang up from time to time. At one time even Dharma Label beer was dropped in, as evidenced by the cases in Hurley's van.

Apparently, Dharma no longer drops beer. Was Roger the "work man" DWI and Dharma knew and prohibited further alcohol use?

And of course, there's the firearms. Oh, well, I suppose when you're stranded on a mysterious island with murderous, child abducting psychos, one out of three ain't so bad.
