Counterfeit != defective

I agree though that those bloomberg stories indicate that defective drugs are in fact reaching consumers :(

Look at what Pfizer claims they found in counterfeit Viagra:

    Blue printer ink

    Amphetamines, also known as “speed”

    Metronidazole, a powerful antibiotic that could
    cause an allergic reaction, diarrhea, or vomiting

    Too much active ingredient (or not enough),
    which may cause you harm

    Binding agents, such as drywall, that prevent
    the tablet from breaking down in your system

And look what Pfizer claims they found in other counterfeit medications:

    Toxic ingredients, such as boric acid, floor wax,
    brick dust, rat poison, and road paint

    Ingredients that can have dangerous interactions
    with other medications you may be taking

    A completely different medication with
    potentially harmful side effects

Yes I know that Pfizer is hardly a disinterested party. But I still get the impression that there's a lot of defective product out there.

Not just counterfeit, but indisputably defective!
