More than 11 500 hospital emergency presentations related to drug use were reported in France in 2015 through the Oscour network, which covers around 9 out of 10 hospital emergency presentations. More than a quarter of presentations were related to cannabis use and one quarter to opioid use, whereas cocaine, other stimulants and hallucinogens were implicated in a smaller proportion of cases. More than a third of the cases were due to use of multiple or unspecified substances. Four out of every 10 clients who sought emergency care were admitted to hospital, while the remaining clients were discharged home. The mean age of clients was 34 years. The proportions of younger individuals (under 24 years) and older individuals (over 45 years) have increased in recent years.
The emergency department from Hospital Lariboisière in Paris participates in the European Drug Emergencies Network (Euro-DEN Plus) project, which was established in 2013 to monitor acute drug toxicity in sentinel centres across Europe.
