Karachi's deepening drug crisis has begun leaving visible scars on the city's public infrastructure — from missing bridge railings and stolen electrical cables to 33 traffic signals rendered non-functional by cable theft, according to reports citing Pakistani and Sri Lankan media. The crisis, once seen primarily as a human and social tragedy, has evolved into a structural public safety emergency that affects every resident of Pakistan's largest city.

How Drug Addiction Is Destroying Public Infrastructure

The link between addiction and infrastructure damage has been documented repeatedly in 2026. In September 2026, five men died when a dilapidated government school wall collapsed in Orangi Town after they allegedly attempted to extract steel rods from the structure. According to police reports cited by Pakistani daily Dawn, the men had gathered near the school to consume drugs before attempting to strip the steel. The incident laid bare a grim cause-and-effect chain: addiction fuels the need for quick cash, which drives theft of public materials, which in turn endangers the broader population.

Separately, reports in October 2026 confirmed that 33 traffic signals across Karachi were non-operational due to cable theft. Stolen items reportedly include streetlight equipment, gas meters, electric cables, brass fittings and manhole covers — a pattern documented across roads, parks and pedestrian bridges throughout the city.

A City's Infrastructure Under Systematic Threat

The damage is not isolated to a single neighbourhood. Reports citing Pakistani daily The Express Tribune indicate that theft of public infrastructure is widespread across Karachi, with railings stripped from pedestrian bridges and flyover structures in multiple areas. In August 2025, the Natha Khan Bridge on Shahrah-e-Faisal suffered structural damage after steel reinforcement was allegedly removed, creating a large pothole and disrupting traffic flow — an early signal of the crisis now playing out at greater scale.

Sri Lanka's Daily Mirror, which compiled these findings in a detailed report, noted that the consequences extend far beyond petty theft: 'When a stolen cable disables a traffic signal or missing steel weakens a bridge, the damage becomes a public safety issue.' The report argued that neither the Orangi Town deaths nor the traffic signal failures alone capture the full extent of the problem — together, they reveal a systemic failure with roots in addiction, organised demand for stolen scrap, and weak enforcement.

Karachi Ranked Fourth Least Liveable City Globally

The infrastructure deterioration comes against an already troubling backdrop. In July 2026, Karachi was ranked the world's fourth least liveable city on the Economist Intelligence Unit's (EIU) annual Global Liveability Index 2026, placing 170th among 173 cities assessed. The only cities ranked below Karachi were Dhaka, Damascus and Tripoli.

Karachi's overall score was 43 out of 100. It scored just 20 on stability, 54 on healthcare, 36 on culture and environment, 75 on education and 52 on infrastructure. The EIU index, a globally recognised benchmark, assesses urban liveability across healthcare, stability, culture and environment, education, and infrastructure.

Who Benefits — and Who Is Accountable

Reports raise pointed questions about the supply chain that makes such theft possible: who purchases stolen scrap materials, and why do scrap dealers face little meaningful scrutiny? Critics argue that enforcement gaps — at both the addiction and the scrap-trade levels — allow the cycle to continue unchecked. The drug problem in Karachi, as analysts note, is no longer confined to the individuals struggling with substance dependence. It is, as the Daily Mirror put it, 'etched into the city's streets, crossings and public structures.'

Authorities in Karachi have yet to announce a coordinated crackdown addressing both the addiction crisis and the organised theft of public assets. With the EIU ranking, recurring fatalities, and mounting infrastructure damage all converging in 2026, pressure on city and federal officials to act is intensifying.
