The centre’s managers and officials are also under investigation, Iran Wire reported citing the judiciary’s Mizan news agency.

It further added that the centre’s capacity was about 40 people.

Reportedly, such incidents are not rare in Iran and are majorly because of the disregarding of safety measuring, ageing facilities and inadequate emergency services.

According to the UN Office of Drugs and Crime, Iran has one of the most severe addiction problems in the world.

Moreover, the country lies on the main trafficking route for poppy, the source of opium and heroin, from Afghanistan to Western Europe, according to Iran Wire.
