Edge Hill University wants members of the public to take part in its study into the effects of Ecstasy on memory and other mental processes.
Philip Murphy, the principal investigator, and his colleagues are looking for people aged between 18 and 30 who have had experience of using both Ecstasy and cannabis, or cannabis alone. Eligible applicants will be given £10 in supermarket vouchers to thank them for their time, which should help offset the expense of munchies.
