N. Macinnes et al., Former chronic methylenedioxymethamphetamine (MDMA or ecstasy) users report mild depressive symptoms, J PSYCHOPH, 15(3), 2001, pp. 181-186
Previous work has indicated recreational use of methylenedioxymethamphetami
ne (MDMA or ecstasy) is associated with elevated scores on self-report meas
ures of depression. We sought to examine the long-term effects of consumpti
on on depression in a group of individuals who had consumed large quantitie
s of the drug in the past, but were now leading relatively drug free lives.
Respondents to this study (n = 29) had consumed an average of 1.5 ecstasy
tablets in the last month, 8.4 in the last 6 months and 23.3 in the last 12
months. The estimated total consumed was 527 tablets, indicating that thes
e respondents were indeed former chronic users of the drug. None of the res
pondents had consumed ecstasy in the last 14 days. Levels of depression (Be
ck's Depression Inventory) were significantly (p < 0.01) elevated compared
to a matched non-drug using control group. Within the group of former chron
ic users, these levels of depression were not significantly affected by cur
rent use of alcohol, cannabis or amphetamine, but were positively correlate
d with an external locus of control (p < 0.05), infrequent but severe- (p <
0.05) and frequent but mild(p < 0.005) self-report measures of life stress
. Multiple regression indicated that levels of frequent but mild life stres
s (p < 0.005) and the quantity of ecstasy tablets respondents consumed over
a 12-h period (p < 0.05) were the only variables that were significant pre
dictors of self-reported levels of depression. The results of this study in
dicate that former chronic ecstasy users report higher levels of depression
than their matched controls.
