Subjective Measures. MDMA increased ratings of Drug
liking relative to PLC (t(24)=-3.93, p= .001) but MA did not
differ from PLC (t(24)=-2.00, p= .06). Both MDMA and MA increased
wanting more drug ratings compared to PLC (MDMA, t(24)=-3.32,p=. 003; MA, t(24)=-2.38, p=. 03). For VAS ratings, MDMA
significantly increased feelings of friendliness compared to PLC
(t(23)=-2.06, p= .05), as did MA (t(23)=-2.15, p= .04).In
contrast, MA but not MDMA increased feelings of sociability
(t(24)=-2.14, p=04 ) (Figure 1).
