Based on symptoms like dilated pupils and severe anxiety, which substance withdrawal is most likely?

The symptoms of dilated pupils and severe anxiety point towards opioid withdrawal as a likely scenario. While dilated pupils are more commonly associated with stimulant use, in the context of withdrawal, opioids can lead to an array of withdrawal symptoms that include heightened anxiety levels.

Opioid withdrawal can result in physical symptoms such as muscle aches, agitation, anxiety, insomnia, and gastrointestinal distress, as well as psychological symptoms. The anxiety experienced during opioid withdrawal can be quite severe due to the impact of opioids on neurotransmitter systems. As the body becomes accustomed to the presence of opioids, the absence can result in a hyperactive state, leading to symptoms like anxiety and possibly dilated pupils.

In contrast, hallucinogens typically do not result in the physical withdrawal symptoms observed with opioids. CNS depressants, when withdrawn, often lead to slower vital responses rather than heightened anxiety and may include other symptoms like tremors and confusion. Dextro-amphetamines, being stimulants, may also cause anxiety and dilated pupils during withdrawal, but the severity and combination of symptoms align more closely with what is commonly observed during opioid withdrawal.

Overall, understanding the specific symptoms associated with these substances and their withdrawal phases is crucial in determining the correct answer
