The document also said the addition of an inhalation room would be vital for the long-term future of the facility.

Health experts involved with The Thistle previously said they were “keen” on the idea but smoking laws in Scotland and drugs laws set in Westminster would need to change before pipes could be supplied to users.

The report stated: “For The Thistle to be effective, it must be able to meet the needs of the population it is trying to help, which it cannot do without an inhalation room.

“As well as making the facility accessible to those who inhale drugs, encouraging visitors to change their method of consuming drugs from injecting to inhaling can be an important harm reduction step.”

MPs also called on the UK government to place The Thistle on a more stable legal footing, describing the current situation as precarious.

After years of political wrangling, The Thistle was able to go ahead after Scotland’s senior law officer, Lord Advocate Dorothy Bain, said users would not be prosecuted for possessing illegal drugs while at the facility.

The report argues that should be the pilot be considered a success upon ending, then UK legislation should create a new legal framework to properly operate and regulate both the site, and any potential future rooms.

The committee had been told the UK government does not support drug consumption facilities and would therefore not make legislative changes in support of them.

The committee said the UK government should adopt “an evidence-based approach” to the facility rather than deciding in advance.
