10 Things Not to Do if You Want Someone to Stop Smoking

Use Anger

Depending on who you ask, anger can make people want something more or less. A 2010 study in Psychological Science found that flashing pictures of angry faces before showing people images of objects made them want the object more than when they viewed happy or expressionless faces [source: APS]. Other studies have shown that anger motivates people to act productively [source: TIME]. Applying either approach to helping someone quit smoking however, probably has a lot to do with an individual's personality. Shouting at someone in red-faced anger and then holding up a pack of cigarettes probably won't make them quit. In fact, it might just inspire them to light up.

Using anger to try and influence someone to quit smoking might be a lot less about the person who's smoking and more about your own anger. If personal feelings against smoking are so strong that you can't talk about it without raising your voice, hostility can get in the way of lovingly influencing and supporting someone to try quitting.
