Between 2019 and 2021, a photovoice research project was conducted in Marseille involving 7 participants, focusing on the practice of injection in public spaces. The use of photovoice, a participatory research method introduced by Wang and Burris in 1997, entailed providing participants with cameras to document their practices. In this article, we revisit the trajectory of the study to illustrate the extent to which this methodology diverged from conventional survey approaches. The use of photography raised specific ethical concerns, as it functioned both as a record and a memory generator. The participants engaged with the project through the 27 exposures available on disposable cameras. The collection of photographic evidence and the narratives they provided offer insights into their political commitment and the collective identity they navigate in their daily street experiences. By employing a clue-based analysis, as proposed by Piette in 1992, the photographs shed light on the spatial and material dimensions of drug use, as well as the symbolic and emotional facets.
