A Bradford firm which sells pioneering drug testing kits for businesses and concerned parents is to hit the TV screen again.

This time, Modern Health Systems Ltd will be helping out Richard and Judy with a feature on girls who go out binge drinking.

The firm was happy to supply breathalyser-style testing kits for the show to use when quizzing women on a Leeds night out.

The link with the Channel 4 show follows the use of the kits on ITV1's Trisha when parents used them to find out if their children had drugs in their bloodstream.

Company boss and former Bradford police superintendent Les Vasey said he welcomed the additional publicity for the kits which are proving increasingly popular with parents.

"The producers were wanting a way of testing people for their feature about alcohol misuse among young women," he said. "They wanted reliable, easy-to-use equipment."

And Mr Vasey said the company, which sells the kits through its website at www.easy-tests.com, was continuing to expand. One big growth area is advising firms on testing employees for drugs and alcohol."One company believed 30 per cent of its workforce was on cannabis and more firms are going to have to look at this," he said.

"In the past, it has largely been big industries such as petrochemicals, but we are taking more inquiries from white-collar businesses which have productivity concerns."

Mr Vasey said, on average, 15 per cent of workplace tests proved positive. Accidents and absenteeism associated with drugs cost British industry £12 billion a year.

Bradford firms had tended to be more reluctant to look at the technology, which uses urine, hair and oral fluid for the tests. But he expected more to sign-up with the publicity surrounding cannabis, which is set to have its status as a drug reduced.

"Use of cannabis has really taken off since the Government started talking about it," he said. "Firms are looking at this type of test because it is less intrusive and easy to use."

Modern Health Systems, which has a team of trainers plus access to 500 counsellors around the UK, is growing at around 25 per cent a year and has received financial support and advice from Yorkshire Ventures.
