Final answer:
The influence of drug-abusing friends fits within the meso-level of Rappaport's levels of analysis, which examines interactions within smaller groups that are part of a larger community.
Step-by-step explanation:
When considering Rappaport's "levels of analysis" perspective in psychology, the influence of drug-abusing friends would best fit within the meso-level. The meso-level deals with interactions between smaller groups within a community or institutions like schools. In this case, the drug-abusing friends represent a smaller social group within the broader community that can directly influence an individual's behavior. This level is in between the micro-level, which looks at personal, and individual interactions, and the macro-level, which considers broader societal trends and large institutions.
