From 2007 to 2011, the government estimates the number of emergency room visits involving the neon-labeled beverages shot up from about 10,000 to more than 20,000. Most of the cases involved teens or young adults, according to the survey of the nation's hospitals released late last week by the Substance Abuse and Mental Health Services Administration.
More than half of the patients considered in the survey told doctors they had consumed only energy drinks. In 2011, about 42 percent of the cases involved energy drinks in combination with alcohol or drugs, such as the stimulants Adderall or Ritalin.
The beverage industry says energy drinks are safe and there is no proof linking the products to adverse reactions.
