Cocaine
Europe

Cocaine is the second most popular illegal recreational drug in Europe (behind cannabis). Since the mid-1990s, overall cocaine usage in Europe has been on the rise, but usage rates and attitudes tend to vary between countries. European countries with the highest usage rates are the United Kingdom, Spain, Italy, and the Republic of Ireland.

Approximately 17 million Europeans (5.1%) have used cocaine at least once and 3.5 million (1.1%) in the last year. About 1.9% (2.3 million) of young adults (15–34 years old) have used cocaine in the last year (latest data available as of 2018).

Usage is particularly prevalent among this demographic: 4% to 7% of males have used cocaine in the last year in Spain, Denmark, the Republic of Ireland, Italy, and the United Kingdom. The ratio of male to female users is approximately 3.8:1, but this statistic varies from 1:1 to 13:1 depending on country.

In 2014 London had the highest amount of cocaine in its sewage out of 50 European cities.
