I have started mixing mdma and ketamine for a different usual effect. Last night I had a gram of ket and a gram of mdma, mixed together in lines. The trip was mind blowing, whole thing like a dream; the room and people I was with kept changing and every hour or so when swim came around the turn back to reality was odd and intense. The trip also seemed to have its own soundtrack which run alongside all the events and strangeness. Are there any risks with mixing these two together? And is there another way to make the trip more intense or strange?
