Samples should pass scrutiny, BUT, many drugs are not sampled (generics, most controlled meds).Sample pkgs are generally designed to maximize ad space, not to be space efficient. If "trimmed", then they may not pass scrutiny any better than other re-packaged meds.

Multiple "meds in baggies" can then be placed in a "harder" container (pill bottle, altoid tin, etc. Whatever is size appropriate.) to achieve both space efficiency and med protection.

BreathingMeat:
Unfortunately there are no CLEAR international standards, only general agreement, with varying degrees of enforcement re prescriptions.

Simon:
Check with a pharmacy that has a contract to supply long-term facilities ( nursing homes, etc), it should be equipped to blister pack meds ( though it may only be in month-long "pages")
