Recently shocking photos have emerged showing the effect that the illegal substance 'Black Mamba' is having on people on the streets in Derby City Centre. The past week has seen a police crack down in the St Peter's quarter as police try to tackle the growing problem that is not just effecting Derby City Centre, but cities around the country.
The drug, which is a synthetic form of cannabis, is highly addictive and leaves people in a "zombie" state, often remaining standing while apparently unconscious.
The pictures were taken by Derbyshire police, who are determined to crack down on dealers distributing the drug in the city centre. They say the two individuals pictured are believed to be under the influence of the drug.
Derby North MP Amanda Solloway said she was "deeply disturbed" at the situation.
Mrs Solloway, who campaigns on mental health issues, said: "It's incredibly shocking to hear of these stories where people are in dreadful and very vulnerable states in the city centre and in the middle of the day
"It's having a horrible effect on them and it's been worrying reading the Derby Telegraph and seeing the extent of the problem.
"However, I'm pleased to hear this is something the police are taking very seriously and treating as a priority. It's a very sad situation.
"I have an immense amount of sympathy for people who live and work in the city centre who have to walk through Derby and come across these people.
"I feel sorry for the police and paramedics who have to spend their time dealing with the problem. I think the police are doing a very good job in clamping down on it but they need help and support, I don't think it can all be down to them.
"I think it's a complex issue that needs more than just pro-active police action.
"People will be making a lot of money out of this and it's important that illegal market is also smashed."
