I feel like there's something missing from this Limbaugh story

I have a hard time believing that US Customs is going to detain you for a vial of Viagra. Whether or not the prescription is in your name (Limbaugh's lawyer is now claiming that Limbaugh got the prescription in his doctor's name to avoid embarrassment - which is a bit odd, since Bob Dole is on TV hawking the stuff). It just sounds odd. Odd, as in, something's missing from this story. How much Viagra did they find? Did they find anything else? I just have a very hard time believing that they found, say, 20 pills of Viagra and detain a guy. What are we missing here?
