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?
