This years's Global Drug Survey is now closed.
With over 100,000 respondents from over 50 countries, GDS2016 is one of the biggest surveys of drug use ever conducted.
We want to thank everyone who so generously gave their time and expertise this year as well as our global media and network partners.
We can't say thank you enough!
We'll start data analysis and report preparation in February 2016 using our global network of academic collaborators. Our first results will
come out exclusively through our media partners and our website during June 2016.
Until then please use our free harm reduction and self assessment tools at
Or visit the Global Drug Survey YouTube Chanel.
If you have any questions or want updates on new projects or our latest research findings please e mail us at
Wishing you all a fantastic and safe 2016
