Why would you use ASA (commonly known generically as aspirin in the US, where it does not have trademark status) if you don't have to take anything?
I asked the dental assistant why they prescribe Vicodin. She said that most patients need it. Strange that most patients in the US "need" it, while most patients in Canada getting the same operation do not.
Apparently my humor was wasted ... usually when there is a grin at the end of a sentence, the person is not being serious
