Substance Use Disorder (SUD) is a medical condition characterized by an inability to control the use of substances such as alcohol, drugs, or medications, despite harmful consequences. It affects the brain’s reward and motivation systems, leading to physical and psychological dependence.
Key Features of SUD
- Craving: A strong desire to use the substance.
- Loss of Control: Difficulty regulating its use even when intending to stop.
- Tolerance: Needing larger amounts of the substance over time for the same effect.
- Withdrawal: Experiencing physical or emotional symptoms when not using the substance.
- Neglect: Abandoning responsibilities, relationships, or self-care due to substance use.
