Introduction: Methylenedioxymethamphetamine (MDMA) is an amphetamine- derived psychostimulant, usually known as "ecstasy." The long-term neuropsychological effects of MDMA are examined in several studies with conflicting results. The most common findings reported are depression, anxiety, and memory and attention deficits. In addition to acute psychotic reactions observed after MDMA use, serotonergic and dopaminergic toxicities may increase the psychosis risk in the long-term. Cannabis usage among MDMA users is very high. The aim of this study was, therefore, to examine the additive effects of cannabis and MDMA on subclinical psychotic symptoms (SPS).
