The following are dependence producing drugs, EXCEPT?

Appeared in: CGHS SSC - 2018

Explanation

Zinc is an essential trace mineral, not a drug. It is vital for immune function, wound healing, and cellular metabolism.
It has no psychoactive effects on the central nervous system, meaning it does not alter mood, perception, or consciousness.
Because it is not psychoactive, Zinc does not produce tolerance, dependence, or a withdrawal syndrome upon cessation.

Option B: Opioids (e.g., heroin, morphine) are a class of drugs well-known for causing profound physical and psychological dependence, leading to severe withdrawal symptoms.
Option C: Cocaine is a powerful central nervous system stimulant that produces intense psychological dependence and a strong compulsion to use the drug.
Option D: Alcohol is a CNS depressant that leads to both physical and psychological dependence. Abrupt withdrawal can be severe and even life-threatening.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of substances that cause drug dependence as background academic context rather than a clinical decision trigger.
Nurses must be able to distinguish between substances of abuse and therapeutic agents or nutrients to conduct accurate patient assessments and provide appropriate education.
Recognizing the signs of withdrawal from substances like alcohol and opioids is a critical nursing skill for ensuring patient safety, as withdrawal can be a medical emergency.
A nurse's role includes screening for substance use disorders and referring patients to appropriate resources for treatment and support.
