“Chronic” means “ongoing”, not “severe”. Given the details in the open access paper, I think this needs more study to find the threshold that matters, and also the highest number I found in this study with in browser search for “ mg” was 200 mg so arguing about 300 vs. 50 just seems silly.

200mg is not the highest number but the threshold they seem to define for chronic. There are definitely people who drink way more than 200mg as that's only about 2 cups of coffee. I assume heavy cafeine users go above 300mg.

“In this study” is an important part of the sentence you quoted.

Before learning about caffeine psychosis, my peak caffeine consumption was probably 8 cups/day where each cup was 2 table (not tea) spoons, so, ah, in retrospect terrifying: http://www.wolframalpha.com/input/?i=caffine%20in%2016%20tab...
