THE level of caffeine laced with alcoholic drinks should be restricted by Scots law, a former health minister has claimed.

Alex Neil, MSP for Airdrie and Shotts, wants to see a definitive legal limit set in a bid to stifle anti-social behaviour.

The SNP stalwart argues the likes of Buckfast tonic wine, which contains more caffeine than Red Bull per 100ml, must be subject to greater guidelines.

Hise call was issued as Scotland secured the right to introduce minimum unit pricing for alcohol; however, Buckfast will not be affected.

Mr Neil said: "Buckfast is a blight on many communities and it often leads to young people becoming hyperactive and engaging in anti-social behaviour.

"The problem is not just alcohol but the combination of caffeine and alcohol. A limit on caffeine should be supported."

A spokesperson for the company which makes the drink admitted he was "somewhat surprised" by the MSP's comments, adding he had not called for the restriction while in office.

The Buckfast Abbey Trust also rejected the claim the substance had any influence on disorder in Scottish communities.

The Scottish Government said they would not rule out introducing a policy along the lines of Mr Neil's suggestion at some point in the future.

A spokesperson added: "While huge progress has been made in tackling alcohol misuse, we want to go further. We will consider proposals as part of the alcohol strategy refresh, but all proposals need to be evidence-based."
