Parenthetical to this post by OneSTDV comes results from the GSS showing that smokers have fewer friends than non-smokers do, (medians of 4 and 5, respectively; means of 6.9 and 7.7, respectively). These items are only able to be cross-referenced in 1986 (n = 1,463). Smoking wasn't cool then, and after a couple of decades of visceral crusading against it, it's now something mostly reserved for low-class, antisocial types to do in shame, away from everyone else.
So it's almost certainly even less cool now than it was then. We probably have to go back a generation before that to find a time when smoking was hip, rather than immaturely rebellious, as it was in the 80s and early 90s, or prolish as it is today.
