The zombie drug turning the streets of British cities into scenes from 'dystopian horror films' is being mass-produced in Chinese labs by moonlighting chemists before being smuggled into the UK through the post.
The powder used to create Spice, the banned drug, is being sold online for as little as £880 a kilo which is opening the door for dealers to make massive margins with 4 gram bags being sold on the streets of London for £60.
I hate coming out late, especially when it's dark, they're all there and I literally run to the bus stop.'It's scary, they walk like zombies and it's not nice to see.'Stephanie Martingale, 32, another Debenhams worker, said Spice usage was putting a strain on the NHS.
She said: 'Yesterday at the market a guy was on the floor and the lady said "leave him, he's been there three hours", the paramedics came before and he's done the exact same thing again.
She said: 'We have seen some disgusting things as well when they are completely out of it.
In Manchester ambulances are now being 'called out dozens of times a day' to Spice cases.
Spice is a synthetic high which falls into a category of drug-like substances that can be bought in shops or online without breaking the law, but which give the body the same artificial rush of endorphins - or 'high' - as illegal drugs such as cannabis or ecstasy.
Chief Superintendent Wasim Chaudhry, from Greater Manchester Police’s city centre team, said officers were doing all they could to tackle the issue but it was 'a problem that we cannot afford to get any worse'.
He said: 'Those who take Spice are often left incapacitated or seriously ill and need the help of our partners in the NHS and ambulance service.'They can also become aggressive and become a danger to themselves and others.'The truth is, tackling the issues caused by Spice is putting pressure on public services and is taking up a lot of our resources.
'It's one thing them sat there begging, seeming quite sober and not aggressive but if there's three or four of them lying in the road shouting at each other you really don't feel safe for your children or other people.' Businesses in Manchester say the Spice epidemic is making their lives a misery.
