I know plenty about the MDMA. Was created in early 20th century as a diet drug.
Incorrect.
MDMA was discovered in 1914 as part of a manufacturing process and noted as a curiosity. It wasn't experimented with again until mid-century. It was first called "Adam" by pyschologists, because they felt it put the user in touch with a more innocent state of mind. Some dealer, some where called it ecstacy and the name (because it's a good one) stuck.
