bring pipe on airplane?

So i'm flying back from amsterdam to houston tomorrow, and wanted to know if i should bring my glass pipe (it's been used, probably about 1-2oz smoked). i would put it in my suitcase under the airplane, but i was wondering if dogs or screenings would catch it and give me a ticket or something... i've never seen dogs in schiophol or IAH, but could they arrest me or something if i had it in my packed bags?
has anyone done this?
thanks dudes

Used pipes are paraphenalia.
Even the workers at the head shop can tell when you try to return a used glass piece, just by sniffing it, even if you HAVE cleaned it with formula420. And dogs have far better noses. Not worth the risk.
Please don't try to bring any cannabis products or paraphenalia on airplanes.
