They probably should question them. Even something as seemingly benign as Paracetamol is not without its issues if used too often, or after alcohol. It can do serious harm. Most medicine can.
Another fun medicine fact. Australia banned the sale of pseudoephedrine from store shelves quite some years ago to try and reduce domestic amphetamine production. Ever since, all of the major pharma brands have sold phenylephrine based cold and flu medicine as a replacement. Our Therapeutic Goods Administration recently found that this preparation is no better than placebo. We're talking about a billion dollar industry that has been knowingly selling snake oil for ten years.
I guess what I'm saying is a healthy dose of skepticism and knowledge seeking should be applied to anything you are putting in your body or exchanging money for. The pharmaceutical industry are not saints. They're just as driven by profit incentives as every other business.
Nobody uses dropbox because they like dropbox. They use it because it's usually the only such service supported by the stupid fucking app they need on the stupid fucking ipad their company insists they use which has no other viable way to put files on and off of the fucking cunting thing because apple is fucking stupid and so is this god damn company.
Someone once told the IT manager that apple devices are "the most secure" and he doesn't even fucking realise that by forcing us to use fucking stupid third party fucking services like fucking dropbox to get files on and off that they are subjecting confidential commercial fucking information to being fucking exposed to third fucking party boneless fucking cunts.
