Deteriorating Cost-Benefit Ratios for Ecstasy/MDMA with Repeated Usage
68 recreational Ecstasy/MDMA users were categorized into four subgroups: light versus heavy users (+20 occasions lifetime), subdivided into current and former users (usage within 6 months). Each unpaid volunteer completed a questionnaire about their personal experiences on Ecstasy/MDMA. The four questions here covered experiences the first and last times on Ecstasy. Positive effects were assessed using a ten-point rating scale from 1 (none) to 10 (maximum), while ‘negative’ effects were
