On Tuesday, the Massachusetts pharmacy board ordered Wal-Mart to stock emergency contraception pills at all its stores in Massachusetts.  Massachusetts is the second state to require the world's largest retailer to carry the morning after pill.

The unanimous decision by the pharmacy board came two weeks after three women, backed by abortion rights groups, sued Wal-Mart for failing to carry the drug in any of its 44 Wal-Marts and four Sam's Club stores in Massachusetts.  The women had argued that state policy required pharmacies to carry all "commonly prescribed medicines."

For those of you who may not be familiar with the morning-after pill, it provides a high dose of hormones that, if taken up to five days after sex, can prevent pregnancy.  Many right-to-lifers believe that this emergency contraception is a form of abortion since it blocks the fertilized egg from being implanted on the uterine wall. 

I'm interested in knowing what you think.  Is the morning-after pill a means of abortion, or should it be viewed as simply another form of birth control?
