If you want to see where this kind of free-wheeling approach to cGMP certification and product quality gets you - just take a look at the developing world, where big-name generics manufacturers knowingly dump subpar-quality (or even outright dangerous or ineffective) drugs on the market with impunity. This leads to all sorts of unsavory outcomes, and puts healthcare providers in the position of resorting to incredibly unscientific approaches to dosage management (it's not uncommon for physicians in such cases to recommend dosages many times in excess of what's recommended due to extremely poor active ingredient potency, based mainly on strictly qualitative feedback from patients). It effectively reduces the pharmaceutical market to a guessing game. The quality issues seen in the developing world are also directly linked to antibiotics usage practices that directly contribute to development of resistant strains of bacteria.
