Personalized Lip Balm
Although there's no evidence of chemicals in lip balm that cause a physical addiction, the fact that you apply it nonstop or carry it on your person at all times might make you wonder if you're psychologically dependent on it. The truth is, this may in fact qualify as a psychological addiction [source: Feldmeier].
Using lip balm shouldn't interfere with your daily life. If you have to go out of your way to find a tube of the stuff or have difficulty enjoying things or concentrating because you can't take your mind off of soothing your lips, you may have a psychological addiction.
