Behavioural Pharmacology July 11, 2014 A. C. Parrott, Catharine Montgomery, Mark Wetherell et al. 34 citations

Stress develops when an organism requires additional metabolic resources to cope with demanding situations. This review will debate how recreational 3,4-methylenedioxymethamphetamine (MDMA, 'ecstasy') can increase some aspects of acute and chronic stress in humans. Laboratory studies on the acute effects of MDMA on cortisol release and neurohormone levels in drug-free regular ecstasy/MDMA users...

It is currently not known to what extent repeated usage impacts upon activity of the hypothalamic-pituitary-adrenal axis over a more prolonged period of time. This study investigated the integrated cortisol levels in 3-month hair samples from recent...
