In the English speaking world, it is a slur regardless of whether or not you use it as slang for a cigarette. Do you really believe that using a word is more important than making sure others don’t feel marginalized? Emotional intelligence is partly about empathy and using that to recognize harmful behavior. A sign of maturity and positive personal growth is realizing that your behavior causes others to feel unwelcome and correcting that behavior. It’s fortuitous that, in a thread about signs of poor education, we are having this discussion. Criticisms are learning experiences, not made with malice; malice is purposefully saying something harmful and celebrating it. Will your life truly be ruined by substituting that word so you don’t accidentally hurt someone?

If you knew saying that word could cause pain in others, why would you say it and further celebrate it? OP may not have meant their question this way, but your comment is how I identify people with poor emotional intelligence.
