Epipens are only $20 in Europe

And we could have them over here for that price if we passed a federal law allowing duty free import of medicines from any reasonable first world country.  Like Canada, the EU, Japan, a few other places.  First world countries all have regulations on the sale of medicine.  If they rule a medicine OK for sale to their citizens then it's OK for Americans too.  FDA doesn't get to block imports.  If it's legal in the country of origin, the law shall make it legal here. 
   The reason Epipens are selling for $600 here is that FDA shut down all the competitors.  Nothing fancy in Epipen, its just adrenalin in an easy to use hypodermic needle.  No patents, no nothing, but FDA kindly drove all the competitors off the market.  Nice work for Mylan.
