Nope. I buy it all the time at my local pharmacy. Some don't want to be bothered with the book keeping, I think, so use the "no can" dodge. They do have to record and keep track of who and how often.
My local folks don't even have to ask my name anymore. They are my first stop for any ailment. Most they have solved, and if they cannot, "You should see Dotor, Mr. William."
