Acute mystical-type experiences on the 5 Dimensions of Altered States of Consciousness (5D-ASC) scale.
The combination of LSD (100 µg) and MDMA (100 mg) induced comparable effects to LSD (100 µg) alone. MDMA (100 mg) alone only significantly induced mystical-type effects on the lower-order “blissful state” scale. The data are expressed as the mean ± SEM percentage of maximally possible scale scores in 24 subjects. Statistics are shown in Supplementary Table The LSD + MDMA combination did not induce significantly different subjective responses on the VASs, 5D-ASC, MEQ, or AMRS compared with LSD alone (Figs. Subjective “any drug effects” lasted an average of 1.5 h longer after the LSD + MDMA combination (mean = 9.9 h) compared with LSD alone (mean = 8.4 h;
