Canada is the only country with a universal public health care system that does not include coverage for prescription drugs; lack of drug coverage leads to underuse of necessary medications. Arguments have been advanced for and against a national pharmacare plan. This article investigates six commonly cited reasons for not introducing such a program in order to determine their validity - private plans are doing a good job, public plans should only cover the poor, strengthening the pan-Canadian Pharmaceutical Alliance is all that is needed, a public plan will deny people access to important new drugs, pharmacare will cost too much and pharmacare is just about money. The evidence presented shows that these are just myths.
