These drugs are widely advertised and promoted (why would anyone advertise medication?), given in doctors offices like candy (even free-in the form of samples), and everyone is profiting. Everyone except for the victims whose health issues show up months or even years later.
I think the only safe answer is just that-play it safe: Just say NO to drugs!
There are certainly times when taking medication is beneficial, but those times (in my opinion) do not apply to colds, flus, heart burn, weight gain, mild allergies and so many other symptoms that are your body's natural way of crying out and telling you that there is a bigger issue at hand. We are a culture of "no pain is acceptable" and we want to kill the symptom instead of finding out the source and looking for a cure. It is like "putting a band-aid on cancer", and the band-aid is a toxic chemical.
