# Iran's schoolgirls were the targets of a deliberate, coordinated poisoning campaign

**No verdict.** Thousands of Iranian schoolgirls really did fall ill, and the fear was real. But whether the wave was a coordinated poisoning campaign, scattered low-grade chemical mischief, or mass sociogenic illness (or some mix) was never independently established. Iranian officials gave contradictory accounts and blocked outside verification; reputable experts remained split. On the record available, no explanation is confirmed.

## Summary
From late 2022, thousands of schoolgirls across dozens of Iranian cities reported sudden illness at school: nausea, breathlessness, dizziness, numbness, and strange odors. Coming amid the woman-led protests that followed Mahsa Amini's death, many Iranians concluded that girls were being deliberately poisoned to frighten them out of the classroom. Iranian authorities cycled through denial, talk of a 'hostile plot,' arrests, and claims of stress and mass hysteria. Independent experts split between a real low-grade chemical irritant and mass sociogenic illness. The opacity of the official response made the truth impossible to nail down, which is why the coordinated-poisoning claim, however plausible to many, stays unproven.

## The claim
That the wave of illnesses in Iranian girls' schools from November 2022 onward was not stress, coincidence, or mass psychogenic illness, but a deliberate, coordinated campaign, carried out or tolerated by hardline elements, to poison and terrorize schoolgirls into abandoning their education, in reprisal for the female-led uprising sweeping the country.

## Origin and timeline
- 2022-09: The death in custody of Mahsa Amini, detained by Iran's morality police, ignites months of nationwide, woman-led protests under the slogan 'Woman, Life, Freedom,' met by a violent state crackdown. This is the charged backdrop against which everything that follows is read.
- 2022-11-30: The first widely reported case: dozens of schoolgirls in the religiously conservative city of Qom are taken to hospital after reporting a strange smell and sudden symptoms. A local journalist, Ali Pourtabatabaei, is among the first to document it.
- 2022-12 to 2023-02: Similar episodes recur at schools in Qom and begin appearing elsewhere. Hundreds of videos circulate of girls reporting burning throats, nausea, headaches, and numbness. Officials initially wave the reports away as rumor, underlying illness, or anxiety.
- 2023-02-26: Deputy Health Minister Younes Panahi says the illnesses in Qom and Borujerd were not accidental and appeared aimed at shutting girls' schools, an apparent official acknowledgment of intent that authorities would later walk back.
- 2023-03-01: The wave spreads sharply to Tehran and many provinces. Reporting describes suspected incidents at dozens, then more than 200, girls' schools across most of Iran's provinces. No deaths and no critical cases are reported.
- 2023-03-03: President Ebrahim Raisi frames the episode as a security plot by Iran's enemies to sow chaos and fear. Officials increasingly blame foreign adversaries and 'dissident media' rather than any domestic actor.
- 2023-03-06: Supreme Leader Ali Khamenei calls the poisoning of schoolgirls, if deliberate, an 'unforgivable' crime that should carry the death penalty, publicly acknowledging the crisis after weeks of official dismissal.
- 2023-03-07 to 03-11: Authorities announce more than 100 arrests 'in connection with' the poisonings, some accused of ties to foreign-based media, but name, indict, and try no one. Journalists and family members who press for answers are detained or threatened.
- 2023-04-29: Iran's Intelligence Ministry concludes there was no actual poisoning by toxic substances, attributing the cases to stress, mass hysteria, and malingering, and again blaming enemies for stoking fear. The reversal, from arrests over an attack to a declaration that no attack occurred, satisfies almost no one.

## The evidence, claim by claim
- Claim: The pattern, overwhelmingly girls' schools hit across the country during a woman-led uprising, proves a coordinated campaign to punish and silence female students.
  Evidence: The pattern is real: reporting placed suspected incidents at girls' schools in most of Iran's provinces, and the timing amid the 'Woman, Life, Freedom' protests made a reprisal reading natural. A senior health official, Younes Panahi, even said early on that some cases were deliberate and aimed at closing girls' schools. But no perpetrator, organization, or motive was ever identified in any transparent proceeding; Iran announced over 100 arrests yet tried no one and named no attacker. A striking pattern is not, by itself, proof of a directed plot, and here the directing hand was never shown.
- Claim: The girls were chemically poisoned; toxic gas was detected.
  Evidence: Officials gave contradictory accounts. One health official floated 'nitrogen gas'; others, and finally the Intelligence Ministry, said no toxic substance was found. A University of Leeds environmental toxicologist who reviewed blood-test results from affected girls reported no evidence of toxins. No chemical agent was ever publicly and credibly identified. Given how tightly Iran controlled the samples and the narrative, absence of a confirmed toxin does not prove nothing harmful was ever present; it does mean chemical poisoning was never established.
- Claim: It cannot be psychological: hundreds of videos show girls genuinely, physically ill.
  Evidence: The symptoms were real, but that does not settle the cause. Mass sociogenic (psychogenic) illness produces genuine physical symptoms, nausea, breathlessness, fainting, with no toxic trigger, and typically spreads through tight-knit groups by sight, sound, and an unfamiliar smell. Psychiatrist Simon Wessely of King's College London saw hallmarks of it; statistician and epidemiologist Ali Arab of Georgetown called a purely psychogenic explanation 'absurd' given the scale and evidence. The World Health Organization had judged a similar wave in Afghan girls' schools (2009 to 2012) to be mass psychogenic illness. Experts stayed genuinely divided.
- Claim: The government's own admissions prove a real attack took place.
  Evidence: Officials said mutually incompatible things over a few weeks: it was rumor and stress; then it was deliberate and aimed at girls' schools; then it was a foreign 'security plot'; then it was mass hysteria and malingering with no poisoning at all. A narrative that shifts this much cannot anchor a firm conclusion in any direction. The contradictions are themselves part of why the episode could never be independently verified.
- Claim: Officials blamed stink bombs and pranks, so the whole thing was harmless mischief.
  Evidence: The Interior Ministry said some incidents involved 'harmless and smelly substances,' suggesting stink-bomb-style pranks or copycats. That may account for some episodes, but it was asserted without named culprits or public evidence, and it sits awkwardly beside thousands of reported hospitalizations. Families, teachers, and rights groups rejected it as a way to minimize the crisis. Like the other official framings, it was neither substantiated nor independently checkable.

## Why people believe it
- The timing was damning. A state that had just spent months violently suppressing women and girls in the streets was, to many Iranians, exactly the kind of actor that might tolerate or orchestrate an attack on girls' schools. The suspicion grew from real, recent repression, not from nothing.
- The official response looked like a cover-up. Weeks of denial, then a 'foreign plot,' then arrests of no one identifiable, then a flat claim that no poisoning had occurred: each turn eroded trust and made the darkest reading feel like the honest one.
- The people who reported it were punished. The journalist who first documented the Qom cases was detained, family protests were met by riot police, and schools were reportedly told not to report new cases. Silencing the messengers reads, to a wary public, as confirmation.
- There was a regional template for it. Attacks on girls' education elsewhere, including the earlier Afghan school-poisoning scares and acid attacks on women, gave the wave a ready-made frame of misogynist violence into which it slotted.
- Mass sociogenic illness, offered by officials as the explanation, has a long history of being used to dismiss the distress of women and girls. To many Iranians, hearing the state reach for 'hysteria' sounded less like science than like an excuse.

## Open questions
- No credible, independent toxicology was ever released. What chemical agent, if any, was involved in any of the incidents remains unestablished, because outside experts were never given verifiable samples or scene access.
- Whether any episodes were deliberate, and if so who was responsible (hardline vigilantes, state actors, copycats, or pranksters), was never adjudicated in any transparent trial. The 100-plus announced arrests led to no public prosecution.
- How much of the wave was sociogenic spread and how much, if any, involved a real irritant may be impossible to disentangle after the fact, given how the cases were documented and how quickly the official story changed.
- The full scale is itself uncertain: tallies ranged from hundreds into the thousands, drawn largely from social media and constrained state reporting, with no independent count possible.
