The Europe-wide study including over 60 cities revealed a picture of distinct geographical and temporal patterns of drug use across European cities. There are two ways to visualise the data from this study, either viewing the data on a map or using a specially-developed charting tool. You can switch between the two views at any point. Please note that the data used for this visulisation also includes the year 2016 — the text in the Analysis has not yet been updated to reflect this.
How to use the charting tool? To explore the findings of the study, select the 'city' of choice and the 'target drug'. You can compare sites or explore daily and yearly trends. Weekend means refer to the mean loads detected on Friday, Saturday, Sunday and Monday. Weekday means refer to mean loads detected on the other days of the week. The findings from 2011-2016 are included in this tool.
Filter results by selecting which sites to display from the list below. Note that not all sites have data entries for all possible drug, year and day values.

How to use this map? By scrolling over the bubbles, the city name and data become visible. By zooming in on your country of interest, additional cities will show allowing further exploration of the city level data in your country of interest. To further explore the findings of the study, select the ‘target drug’ and the ‘temporal pattern’ of choice. Weekend means refer to the mean loads detected on Friday, Saturday, Sunday and Monday. Weekday means refer to mean loads detected on the other days of the week. The findings from the 2011-2016 period are included in this map. Bubble sizes are not comparable between different target drugs, but are comparable within one substance.
