Which of the following symptoms are associated with withdrawal from substances?

Withdrawal symptoms from substances can vary based on the type of substance used and the severity of the dependence, but many common physical signs are well-documented. Symptoms associated with substance withdrawal often manifest as physical discomfort and can include shaking, fever, and vomiting.

Shaking is frequently observed during withdrawal as the body reacts to the absence of a substance it has become dependent on. Fever can occur as a result of the body’s response to the withdrawal process, causing increased metabolic activity as the system tries to regain homeostasis. Vomiting is another common symptom, often indicating the body's distress and the gastrointestinal system reacting negatively to the absence of the substance. Together, these symptoms highlight the physical impact that withdrawal can have on an individual, underscoring the challenges faced during the recovery process.

In contrast, the other options describe characteristics that are not directly related to withdrawal symptoms. They focus more on emotional states or behaviors that do not align with the physical nature of withdrawal.
