Energy Drinks: Is It Time To Tighten Regulation?

Concerns about energy drinks have been gathering pace, with some groups, particularly in the US and the UK, now calling for them to be more tightly regulated and for greater public awareness of what they contain, their potential side-effects and risk of addiction.
Public perception and consumption of energy drinks appears to have shifted from dietary supplementation to recreational use, and some might now even say, recreational abuse, with the latter perhaps boosted by the arrival of alcoholic energy drinks, the dangers of which have been illustrated with the recent hospitalization of nine US students aged 17 to 19, allegedly for consuming too much Four Loko, an alcoholic energy drink that is colloquially referred to as "blackout in a can" or "liquid cocaine".
If energy drinks aren't necessarily supplying us with energy, what is their appeal? The answer is, caffeine. And that is where the concern arises, for caffeine in excess, particularly for young people consuming too much too soon, can lead to some unpleasant, and dangerous symptoms.
Caffeine intoxication is a clinical syndrome that is accepted by authorities such as the Diagnostic and Statistical Manual of Mental (DSM) Disorders and the World Health Organization's International Classification of Diseases (ICD). They say that caffeine intoxication can lead to nervousness, anxiety, restlessness, pacing (psychomotor agitation), insomnia, stomach upset, tremors, rapid heartbeat, and in rare cases, even death.
