Someone might eat deodorant due to a rare condition called pica, which causes cravings to eat non-food items. Eating deodorant can become an addiction, as in the case of a 19-year-old woman named Nicole who described craving deodorant throughout her day to self-soothe and manage anxiety. She started eating deodorant at the age of four and developed a full-blown addiction by her late teens. This behavior may also be linked to mineral deficiencies like iron or zinc in children or adults. Eating deodorant is dangerous because it contains chemicals like aluminum that can cause serious health issues over time, including stomach pain, seizures, dementia, and increased risk of cancer. Psychologically, the compulsion often serves as a way to self-soothe anxiety, but medical attention is necessary to address this harmful behavior. In short, eating deodorant is a manifestation of pica related to psychological or mineral deficiency factors, and it is both addictive and harmful to health.
