This paper shows how the second wave of the European Web Survey on Drugs (EWSD) led to a better understanding of the drug situation in Luxembourg. Until the EWSD, detailed information on the drug situation in Luxembourg was very limited, with only a few surveys, often small-scale, having been conducted in the country since the late 1990s. As shown in the paper, the EWSD was able to provide new and complementary information that allowed for deeper insights into patterns of drug use in the country. The paper also offers reflections on the methodological challenges and lessons learned in conducting the survey.
