I don’t have much to say about Thai girls. However, in the west, MDMA is often faked - not just cut. I can’t find the results of a study, but it is a large chunk of the MDMA sold. And I can almost guarantee that Thailand has an even higher fake MDMA rate then Europe and NA. So it is very possible this guy never actually took MDMA.
Just my two cents.
