CAN TOO MUCH COFFEE CAUSE HALLUCINATIONS?
Perhaps you have heard the conflicting reports about caffeine and your health. The latest news to come out is the apparent link between hallucinations and caffeine intake of more than seven instant cups of coffee.
Some words of caution:
This study looked at stress of the respondents, but now ow much sleep they were getting.
The study involved self-report of caffeine intake for the participants. Self-report is prone to bias related to memory problems.
Anytime there is a “link” or an “association” in a study, that means the results are a correlation. Correlation is not causation. Therefore, you can not conclude that caffeine causes halucinations or hallucinations cane an increase in caffeine intake.

TOO MUCH CAFFFEINE LINKED TO HALLUCINATIONS
Hearing voices when nobody is around or seeing things that aren't there? Too much caffeine could be to blame. British researchers reported on Wednesday.
Their study found that students who consumed more than the equivalent of seven cups of instant coffee a day were three times more likely to have had these kinds of hallucinations compared to people on a single daily cup.
“This is the first step toward looking at the wider factors associated with hallucinations,” said Simon Jones, a psychologist at Durham University in Britain who led the study.
STRESS HORMONE
For the study published in the journal Personality and Individual differences, Jones and colleagues asked 200 students about their typical intake of coffee, tea, energy drinks and other products containing caffeine. They also measured stress.
They did not ask the students how much they slept.
The next step is to test whether caffeine is actually causing hallucinations or whether people who have them simply consume more caffeine when under pressure, Jones said.
