My simple policy proposal is to allow consumers to purchase drugs from anywhere worldwide. The true Libertarian solution is to repeal all laws restricting the sale of drugs (no prescriptions required), but that will take 100 years of progress toward freedom.
Requiring prescriptions to buy drugs increases the demand for medical services, both doctors and pharmacists. Recognizing that Americans, on the whole and for the most part, are not ready for this much freedom (no prescriptions required), an intermediate palliative treatment for the high costs of medical services is to allow consumers to purchase prescription drugs from any vendors worldwide. For example, in another tab on this web site, the reader will have seen that the EpiPen costs $100 in Canada, versus $300 here, at the time of the investigation (prices change).
