I'm not sure drug importation will work though, not because it's a bad policy per se, but I'm not sure that other countries will let the US import their low-cost medicines if US law changes in order to protect their domestic supplies.
There's Canada as an example case. We have ~10x the population of Canada, and California alone could use up all of Canada's medicines. Not sure Canada would go for it.
Think it's worth a shot though. I know there are some trial programs going into place in Colorado and Florida around allowing drug importation. Will be cool to follow and see how they play out.
