Which term describes genetically transmitted elements that influence drug use?

• A. Inherited risk factors
• B. Risk factors
• C. Protective factors
• D. Drug misuse

Answer: (A)

Genetic influence on drug use is being tested. When we describe elements that are passed from parent to child and can shape someone’s likelihood of using or developing problems with drugs, the term inherited risk factors fits best. These are genetic traits that raise susceptibility—variations that affect brain reward pathways, neurotransmitter systems, or how someone metabolizes substances. They describe a predisposition that comes from DNA and can interact with environment, experiences, and social context to influence drug use behavior. The other terms don’t fit as precisely: risk factors is broader and can be environmental or genetic and doesn’t specify heredity; protective factors are elements that reduce risk; and drug misuse refers to the behavior itself, not the hereditary aspect.
