But things are not what they seem.

The footage is part of a five-minute dramatised documentary shot by A-level students – and it has inspired Hebden Royd town councillors to set up a special youth working group.

The film, Town Of Alcoholic Children, has been posted on file sharing website YouTube and appears to show youngsters chopping lines of cocaine and rubbing it into their gums.

Others aged between 14 and 18 are seen drinking vodka and lager on the street.

It was made by Emma Lund and Alex Quinn, former pupils of Calder High School, Mytholm-royd. They said it was based on real events and was an attempt to highlight youth culture, teen alienation and boredom in the town.

Hebden Royd Town councillors said the film helped crystallise plans to create a youth working group.

Nader Fekri said: "I was shocked when I first saw it but it's only highlighting the problems lots of small towns have – that there really is not much for kids between 10 and 18 to do.

"Its release coincided with our own thoughts that, as a council, we needed to do more and it certainly encouraged us to act.

"The problems these kids have – boredom and thinking Hebden is the worse place in the world – are universal but we need to come with ways to solve them."

Janet Battye added: "We do not want to see this kind of thing on the internet but we have to understand it's highlighting real concerns for teenagers in Hebden Bridge and we have to act."

Calder High's head teacher Stephen Ball said the film had earned its makers a grade A mark and had been praised by an independent film company which was making a film about youth culture in West Yorkshire.

He said: "These are very talented students who have done a fantastic job making a very realistic and hard-hitting film."
