Caffeine linked to hallucinations in study

So that's what is wrong with all those people that I used to work with that drank coffee all day. I wish I would have  known this years ago, I would have dealt with them a little better. they probably were listening to me and the other people that were talking as well. Every year there is a different study about coffee/caffeine.  One year, it is ok to have caffeine, another year, you should not have too much. Exactly, what is too much? What is the standard dosage of caffeine one can have a day if they do not drink coffee? There are so many ways you can get caffeine. Is it just the caffeine in coffee? But the fact that too much will have you hearing and seeing things, is enough for me to call a few friends and tell them to back away from the cup.

You can’t believe everything you hear, especially if you’re polishing off the third refill of your venti coffee. Australian researchers at La Trobe University have just published a study suggesting that people on a serious caffeine buzz are prone to hear things that aren’t there. The study might raise new concerns about the safety of caffeine. But for the average person who’s weary of conflicting reports about coffee and health, the new findings may not amount to much more than background noise.

Evidently deciding that an actual Starbucks would be too loud for science, the researchers brought volunteers to a lab. The subjects — some highly caffeinated, some not — put on headphones that pumped out white noise. They were told that Bing Crosby’s "White Christmas" would be playing in the background, which was actually just a white lie. Even though Bing wasn’t anywhere around, some of the caffeine-addled listeners said they could hear the song. (In their defense, it should be pointed out that the differences between white noise and "White Christmas" are pretty subtle.) The researchers concluded that five regular cups of coffee could be enough to increase the risk of auditory hallucinations.
