Here is the link to Roger Ebert's review of "Smoke," but don't read it if you want to be surprised by all of the plot twists since he gives away several of them (though not the last one which involves Harvey Keitel in a GREAT and memorable monologue).
http://rogerebert.suntimes.com/apps/pbcs.dll/article?AID=/19950616/REVIEWS/506160303/1023 Ebert says in part about the film: "Like a few other recent, brave movies, ["Smoke"] places trust in the power of words."
And later on: "The movie is a delicate creation, with no big punch line or payoff. Watching it, I was in the moment: It was about these people wandering lost through their lives. Afterward, I felt good about them - good because they were likable people, but good, too, because the writer and director took care to give them dialogue that suited their needs. Of all the handicaps in life, the worst must be the inability to express how you feel."
Yes, good likeable people, people who just happen to be smokers.
I hadn't meant to get upset today, but on this theme, I just can't help noting how the antismoker professionals with their junkscience propaganda about ETS and their unceasing demonization of smokers have riven families and destroyed relationships and driven people out of their own homes. It's just awful.
