$this->bbcode_second_pass_quote('', 'I')t would be nice if they would do the same with prescription pharmaceuticals.
They already do. The standards of proof of efficacy and safety are so high that it can cost tens of millions of dollars (if not hundreds of millions) and several years to get a drug to market. Indeed, a new drug doesn't just have to prove its efficacy and safety it has to be demonstrably better than what is already on the market before it will gain favour among the medical community. [*]
Yes, prescription drugs have side effects, sometimes they are dangerous. However, it's worth remembering that *all* drugs and medications have side effects - whether they are made by big pharma or not.
There are 2 key points that are worth remembering - prescription medications will have had their side effect profile very carefully assessed and documented (almost to a paranoid extent, hence the long lists packaged with the drugs), the same is not necessarily true of borderline substances (see my post above).
Additionally, if a drug is prescribed for a specific condition and has proven benefity, then some side effects may be acceptable. E.g. Someone prescribed anti-coagulant medication for multiple previous blood clots, would likely accept the 1 in 100 risk of life-threatening side effects of the medication, instead of the 1 in 10 risk of life-threatening blood clot.
Conversely, if a substance is taken without a clear purpose or proven benefit - then the degree of side effects that could be tolerated is much lower. To continue the same illustration, anti-coagulant medications are excellent at preventing heart attacks - but if your risk of heart attack is only 1 in 1000, then taking the medication is a bad risk.
The reason that many drugs are prescription only is because balancing risks and benefits requires skills, knowledge and training that, in general, only a doctor would have.
[*] This is my experience in the UK. There are strict guidlines about what mediciations can be prescribed and in what circumstances, and these are evidence based. Direct marketing of drugs to doctors is relatively low profile - usually restricted to advertisements in the medical press, or the provision of scientific and marketing literature about a product at educational meetings. Free samples, expensive dinners, etc. aren't allowed. Similarly, prescription medications cannot be directly advertised to the public.
