So, when a new drug is developed and marketed, and the the developer markets the drug as "safe" "non-addictive" etc. - knowing full well it is neither - and doctors use this info when deciding when and who to prescribe to, what is the libertarian response to this? Is it the patients fault when their lives are turned upside down simply because they trusted their doctors advice? Does the developer have no responsibility? And should those whose lives have bee ruined through job loss, relationship breakdowns etc have no legal remedy when drug makers are making billions in profits based on incomplete or partial disclosure? I simply do not understand your reasoning. Do you seriously expect every patient across a broad spectrum of intellectual capabilities and educational backgrounds to research every medication prescribed to ensure they are safe? And what about "new" meds with limited track records?
