Blackpool's emergency services are tackling the fallout from the dizzying array of 'party drugs' that are on the rise in towns across the UK. Mephadrone - aka 'MCAT' and 'Meow Meow', and known as 'Bubble' in Blackpool - is available on many street corners. You can get a hit for the price of a pint of beer, but it can have highly unpredictable effects. PC Kris Beasley, one of Blackpool's longest-serving beat cops, has seen it all, but he - alongside his police, ambulance and fire colleagues - is increasingly facing the fallout from punters who are playing a chemical lottery to get high. Meanwhile the emergency services cope with a never-ending stream of calls, from a man exposing his penis at a railway station, to violent patients and rowdy suspects, including a pair of naked squaddies whose R&R has got out of hand.
