What is one effect that physical dependency can have on a person?

Physical dependency occurs when an individual has developed a tolerance to a substance, leading to the need for continued use to avoid withdrawal symptoms. When someone who is physically dependent stops using the substance or significantly reduces their intake, they often experience a range of withdrawal symptoms, which can include anxiety, irritability, nausea, and tremors. These symptoms are a direct indication of the body’s reliance on the substance to function normally.

In contrast, the other options do not accurately reflect the effects of physical dependency. Increased energy is not a typical response to withdrawal. Improved relationships and enhanced ability to focus are outcomes that may not be associated with dependency and can actually be negatively impacted by substance use. Understanding the implications of physical dependency is crucial for recognizing the signs of addiction and the importance of seeking help.
