"ZOMBIE" addicts are scaling rooftops in the monkey dust capital of the UK - where drugs are posted through your letterbox for £2 per hit.
A new documentary has revealed how "dustheads" in Stoke-on-Trent have lost everything after getting hooked on the drug.
Monkey dust can cause paranoia, hallucinations, aggression and psychosis for up to 12 hours.
The ultra-addictive drug has even made users eat glass, climb three-storey blocks of flats and jump off buildings.
In a new episode of BBC Three's Drugs Map of Britain series, dad-of-seven Paul told how monkey dust cost him his home and family.

Paul said: "It can happen off just one pipe. You can have one pipe and that's it - you're f***ed for the rest of your life.
"It made me lose everything. I could see it going but, I dunno, there was nothing I could do about it.
"I'm here now in this tent because I started smoking dust."
Homeless user and dealer Steve lived in a camp in woods just off the A50 - until it burned down.
Steve said: "I've got no formal income. It's day to day living.
"Stoke is f***ed because of dust. I hate this drug man. I hate it. It's ruining my life."
Another user, Bambi, described monkey dust as the "devil's drug" - saying it is worse than heroin.
He told how he first started dealing cocaine aged five before a "friend" introduced him to monkey dust when he was 14.
Bambi said: "Off that one pipe I was awake for four days. Having a mint one.
"I wish I never took that first pipe because it has ruined my life. I have to have the bong just to get out of bed.

The BBC said it changed some personal details to protect interviewees' identities.
Monkey dust arrived in Stoke in the mid-2000s, costing just £2 per hit.
The drug soon became popular with homeless people unable to afford cocaine or hard spirits.
But even experts are baffled about how Stoke became the monkey dust capital of the UK.
The yellow-grey powder is a class B drug - and possession could land you a five-year prison sentence.
Two-third of monkey dust users in Stoke also use heroin, which is a class A drug.
Users told the documentary how monkey dust arrives in the post after they order it on Facebook and LinkedIn.
There is currently no medical substitute to treat monkey dust addiction.
UK Addiction Treatment Centres said: "Monkey dust addiction can be extremely damaging both physically and mentally.
"It carries a high risk of lethal overdose - effects can occur with as little as 3mg-5mg.
"It can lead to heart problems and kidney damage, cause extreme paranoia and agitation.
"In some cases it has been known to induce hallucinations and psychosis.
"The effects of monkey dust addiction are not limited to physical health either.
"Users may find their relationships, finances, education or career suffer as a result of their dependency.
"Legal issues are also a huge concern both due to monkey dust's drug classification as a Class B substance and the high incident rate of crime linked to monkey dust abuse."
