There was a time when the property of the aspirin to prevent heart attacks, drastically increase the people's chances after a heart attack or prevent a second heart attack were known and well-documented.
By that time aspirin was in widespread use for many decades and all it's side-effects, interactions and properties were well-known.
Unfortunately, according to the FDA rules, it was illegal for the company (Bayer) to advertise that aspirin can prevent heart attacks untill it passed a several years-long standard testing process.
The company could not even say "Aspirin may prevent heart attack but this claim has not yet been verified by FDA". The company officers would go to jail for something like that.
Of course the few tens of thousands unnecessary deaths that such restriction caused were not the fault of the government.
If those dummies with weak hearts were carefully reading medical industry trade journals, they would have known about the healing properties of aspirin.
