Physical dependence, often referred to as addiction, is a condition where an individual relies on a particular substance or activity to function normally. There are many synonyms for this term, including substance dependence, chemical dependency, drug addiction, and habitual dependence. However, physical dependence can also refer to non-substance related activities such as gambling or social media usage. In these cases, terms such as behavioral addiction or psychological dependence can be used. Regardless of the situation, physical dependence is a serious concern that can have detrimental effects on an individual's wellbeing. It is important to seek professional help if you or someone you know exhibits signs of physical dependence.
