__________ drugs refer to types of drugs that lead to the use of other more addictive types of drugs.

• A. Addictive
• B. Gateway
• C. High pressure
• D. Predisposition

Answer: (B)

Gateway drugs refer to substances that tend to precede the use of more addictive drugs, creating a pathway toward greater substance use. The term captures the idea of a progression: early, often less dangerous-seeming substances can normalize or increase exposure to drug-using environments, making it more likely someone will try harder drugs later. That’s why this option fits best—the concept is about a sequence of use, not the inherent addictiveness of a drug, a social pressure term, or an individual vulnerability. The other choices miss that progression: one describes how addictive a drug is, another isn’t a standard term in this context, and predisposition speaks to personal risk rather than a category of drugs that leads to others.
