I thought this was might just grieving parents blaming something coincidental, until reading this article. I didn't know that there are other cases of the spiciness of these new peppers seem to be causing problems for some people. Still no clear evidence, but it's possible there's something.

"These ultraspicy peppers may either contain a unique vasoactive substance, or there is a dose-related effect of capsaicin concentration that can trigger RCVS," the doctors concluded. "Further research in this area is needed to determine the exact pathophysiology of this phenomenon. This case provides further evidence that ingestion of hot peppers may lead to serious consequences and that further research is needed to assess their safety."

Emphasis mine.
