Growing concerns about the use of so-called “energy gum” have prompted warnings in Scotland about excessive caffeine use.
Just one piece delivers 100mg of caffeine into the bloodstream, even higher than the 80mg contained in a 250ml can of Red Bull.
Heart Research UK said 400mg – what is found in four cups of coffee – is safe for adults over a day but there are fears young people are using large amounts of energy gum.
The Scottish Government last month launched a consultation into energy drinks which could lead to them being banned for sale to under-16s.
Labour MSP Mary Fee wants it to be widened.
She said: “Energy gum can include doses of caffeine and it is marketed at young people.
"The consultation is welcome but the same principle should apply to other high-caffeine products.”
