Children are becoming dependent on energy drinks that have dramatic effects on their concentration and behaviour in schools, drug experts have warned.
Schools are being advised to observe children for signs of agitation which could be a result of excessive caffeine consumption. It follows reports of pupils drinking large quantities of energy drinks or taking caffeine-based pills.
The warning, from the anti-drugs advisory group Drug Education UK, comes as ministers prepare to unveil new measures tomorrow to improve school dinners and advise parents on children's packed lunches.
Bob Tait, from Drug Education UK, said: "There is a growing problem of caffeine abuse in schools. Most schools have a drug education programme to advise kids against illegal drugs, but there is less known about legal highs."
He made his warning at a conference of school nurses this week, the Nursing Standard reported. Tait said: "Children will drink them on the walk to school, at break and lunch time. If you have got a child who is worked up on an energy drink, they are going to be agitated during lesson time."
