"If someone drinks five to 10 cups of decaffeinated coffee a day, the dose of caffeine could easily reach the level in a cup or two of caffeinated coffee," said study co-author Dr. Bruce Goldberger, a professor and director of the university's William R. Maples Center for Forensic Medicine.

The results could have implications for people told to avoid caffeine because of certain medical conditions such as high blood pressure, kidney disease or anxiety disorders, according to the study reported in this month's Journal of Analytical Toxicology.

"If someone drinks five to 10 cups of decaffeinated coffee a day, the dose of caffeine could easily reach the level in a cup or two of caffeinated coffee," said co-author Dr. Bruce Goldberger, a professor and director of the university's William R. Maples Center for Forensic Medicine.
