Bathrooms in the United Kingdom's Parliament building have tested positive for cocaine once again.
In 2013, reporters from The Sun on Sunday, swab tested multiple locations in the House of Commons for drugs - and nine came up positive.
This week a new investigation undertaken by Vice has revealed the bathrooms still contain cocaine residue. This time around, only four of nine locations returned positive results.
Vice tested rooms that can be accessed by people holding an access pass, as well as visitors who attend functions and events at Parliament.

- Police called after screaming heard at Boris Johnson's flat
One of the strongest test results came from the bathrooms outside the Strangers Bar.
Both investigations used swabs which can be rubbed across a surface, and will turn blue to indicate the presence of cocaine.
The most recent investigation comes after multiple Conservative MPs confessed to previous drug use.
Michael Gove admitted he had snorted coke on "several occasions" during his years as a journalist.
Rory Stewart said he had smoked opium in Iran, and multiple other MPs confirmed they had smoked cannabis.
Tory front runner Boris Johnson confirmed he had smoked cannabis and was unclear about his cocaine use.
In one interview with Marie Claire, Johnson said he had taken cocaine, and then claimed in another interview with the BBC he had sneezed, and the drugs did not enter his nose.
He then said it might have been icing sugar.
"Parliament takes the issue of substance misuse very seriously and offers a range of welfare and health support services for those who need them," a UK House of Commons spokesperson told Newshub.
"Parliament is a public place and we welcome over a million visitors a year who have access to the facilities. Should drug use be identified in Parliament, appropriate action would be taken."
