A social network perspective on heroin and cocaine use among adults: evidence of bidirectional influences.
Article in Addiction (Abingdon, England), 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
aimsWhile several studies have documented a relationship between initiation of drug use and social network drug use in youth, the direction of this association is not well understood, particularly among adults or for stages of drug involvement beyond initiation. The present study sought to examine two competing theories (social selection and social influence) in the longitudinal relationship between drug use (heroin and/or cocaine) and social network drug use among drug-experienced adults.
designThree waves of data came from a cohort of 1108 adults reporting a life-time history of heroin and/or cocaine use.
settingLow-income neighborhoods with high rates of drug use in Baltimore, Maryland.
participantsParticipants had weekly contact with drug users and were 18 years of age or older. MEASUREMENTS: Drug use data were self-report. Network drug use was assessed through a social network inventory. Close friends were individuals whom the participant reported seeing daily or rated as having the highest level of trust. Findings Structural equation modeling indicated significant bidirectional influences. The majority of change in network drug use over time was due to change in the composition of the network rather than change in friends' behavior. Drug use by close peers did not influence participant drug use beyond the total network.
conclusionsThere is evidence of both social selection and social influence processes in the association between drug use and network drug use among drug-experienced adults.
