Smoking is absolutely disgusting and it's extremely unattractive to see a girl puffing away on a cig while her mouth becomes filled with 10 different toxins.
That reverse, "i'll say it myself so no one else say's it" doesn't work. You're a junky and hence an outcast of society, only accepted by your own friends, who'll unfortunately won't be around for long if they also keep up these vices.
