What people say cured them, and what is actually known about it.

An antiparasitic drug repurposed online first for COVID-19, then for cancer.

A dog dewormer at the centre of the most viral cancer-cure story of the last decade.

The "cancer is a fungus" theory and the household-cupboard cure.

The herbalist staple said to stop haemorrhage in seconds.

The Pauling claim, the oral-versus-intravenous distinction, and a real ongoing research programme.

The original suppressed-cure story, and the one with the largest body count.

Documented here as a poisoning hazard. No accounts are collected for this entry.

A corrosive paste sold as a way to "draw out" tumours.

A pre-antibiotic remedy that never quite went away.

Built on a real Nobel-winning observation, extended into something lethal.

The claim where the palliative benefit is real and the curative claim is not.

A heavily studied compound whose central problem is that the body barely absorbs it.

Forty years of deliberate non-treatment, ended only by a whistleblower and a journalist.

A drug marketed as completely safe, and a company that fought the evidence.

Internal knowledge of cardiac risk years before withdrawal.

A pain epidemic manufactured by a marketing campaign, with a guilty plea to prove it.

The playbook every later denial campaign copied, preserved in the industry's own memos.

The claim that the mid-century polio epidemics were caused by DDT and lead-arsenate pesticide exposure rather than by a virus, and that the post-1955 decline was falsely credited to the vaccine.

The claim that the 1918 pandemic was not viral at all but caused by experimental bacterial vaccines given to US troops, sometimes combined with the argument that aspirin poisoning produced the deaths.

In 1955 Cutter Laboratories released polio vaccine in which the virus had not been fully inactivated. It paralysed 164 people and killed 10.

Polio vaccine produced between 1955 and 1963 was contaminated with simian virus 40, a monkey virus later found capable of causing tumours in rodents.

The US vaccinated 45 million people against a swine flu pandemic that never materialised, and halted the programme after a real Guillain-Barre syndrome signal appeared.

The claim that the MMR vaccine causes autism, originating in a 1998 Lancet paper that was retracted and whose author was struck off.

The claim that the ethylmercury preservative thimerosal, used in some multi-dose vaccine vials, caused a rise in autism and neurodevelopmental disorders.

The claim that vaccinated people shed something that harms the unvaccinated around them. Real for a small number of live vaccines; mechanically impossible for the ones it is usually asserted about.

The claim that adverse event reporting systems reveal mass vaccine deaths being suppressed — and the counter-claim that vaccine injuries essentially do not happen. Both misread what the data is.

An open question rather than a settled one. Two hypotheses — natural spillover and a research-related incident — remain live, and this entry does not pretend otherwise.

The claim that the pandemic was invented or wildly exaggerated, evidenced by videos of quiet hospital corridors.

The claim that death counts were inflated by recording anyone who died with a positive test as a COVID death.

The claim that PCR run at high cycle counts manufactured a pandemic of positives from harmless fragments of RNA.

The public was told masks would not help, then told to wear them. The first advice was not purely a reading of the evidence.

Aerosol scientists said the virus was airborne months before health agencies said so, and were dismissed.

The CIA really did dose unwitting civilians with LSD and fund coercive psychological experiments for two decades, then destroyed most of the paperwork.

The FBI ran a covert programme to monitor, discredit and break up domestic political groups, using forged letters, informants and press smears.

The second of two reported attacks on US destroyers in August 1964 — the one used to justify escalation in Vietnam — did not occur.

The US Joint Chiefs of Staff really did draft a plan to manufacture pretexts for war with Cuba, including faked attacks and casualties.

The public case for invading Iraq rested on weapons claims that inquiries later found unsupported, and on a single discredited source.

Residents told for eighteen months that their water was safe were drinking water with lead levels that officials' own data already contradicted.

The lead industry funded the science, staffed the advisory panels and reassured the public for fifty years about an additive already known to poison the people who made it.

Oil companies' own scientists projected the warming effect of their products accurately, while the companies publicly funded uncertainty about it.

A high-level simulation of a coronavirus pandemic was run in October 2019, which is read either as foreknowledge or as ordinary preparedness work.

Official accounts of the 1963 assassination have been contradicted by a later congressional inquiry, and a portion of the record has still not been released.

The best known 9/11 argument: jet fuel burns cooler than the melting point of structural steel, so the towers could not have come down from fire alone.

A 47-storey tower that no plane hit came down late that afternoon, in a way that looked to many people like a demolition.

The claim that explosives or incendiaries were placed in the buildings beforehand, evidenced by dust residues and puffs of debris from the facades.

The claim that the damage was too small for a Boeing 757 and that a missile or a smaller aircraft struck the building instead.

The claim that United 93 was shot down by a fighter and that the passenger revolt was a cover story.

The claim that the leaseholder said the order to demolish WTC 7 out loud on television, and profited from the destruction.

A section of the 2002 congressional inquiry on possible Saudi connections was classified in full, then released in 2016 — largely vindicating the people who said something was being kept back.

The claim that the attacks came without warning did not survive the record: warnings existed, were specific in places, and were not acted on.

Officials said the air was safe to breathe within days. It was not, they were told internally that the data did not support saying so, and the illnesses followed.

A connection between Iraq and the attacks was repeatedly implied to the public and did not exist.
