We invite anyone who has or is taking Hydrangea or similar substances to take a short online survey to help us understand more about the reasons why individuals take it/them and their experiences of it/them. This survey is part of a research project being undertaken by a final year Master in Pharmacy student at the University of Hertfordshire who is being supervised by an EU-MADNESS team member (John Corkery). University ethics approval has been given for this survey.

Please feel free to pass on this link to others.
