Will a drug test come up positive by touching and smelling a bag with cocaine in it?

If you smelled the bag up close enough then for sure you inhaled some, as far as touching the bag, if absorbed through your skin will also make a positive on the test. It has also been researched that 4 in 5 monetary bills have traces of cocaine on them, so maybe that excuse will work, for they too will create a positive result on a skin test (hands).
