To the reader:

I wanted to add a note to this response: street ecstasy is often laced with other drugs; the most common one is Methamphetamine. Sometimes street ecstasy has research chemicals that can be purchased over the internet. The rumor about getting violently ill after ingesting ecstasy could be related to pills that contained an unanticipated substance. I tend to view ecstasy as a "mystery pill." Even "trusted friends" with "trusted sources" can have pills with undesired substances.  :(
