I'm offering a reasoned analysis of what the actual effects of smoking a cigarette are and whether those things are widely considered luxurious. If you're addicted, sure, smoking offers a great luxury in taking the money off your back for a while. If you're not addicted and don't have some other physical need (e.g. untreated mental illness), it offers a pretty mild buzz and a lot of negatives.

But regardless, wouldn't this be more appropriate as a reply to the parent, who made the initial claim that cigarettes are luxurious and didn't present any reasons for it?
