If there is potential for abuse then that will be reflected in the prosecution in court. If the results from this are easily wrong or tampered with then it won't really hold up in court.

What I'm wondering is if they could use during routine traffic stops, like a breathalyzer? They have you put your index finger on a device and that device tells whether or not you're under the influence of drugs or alcohol at that moment (or if you've been in contact with either).

The tip-off to the presence of drugs has less to do with the actual fingerprints, and more with the sweat that is secreted through the pores of the fingertips and then detected using dyed antibodies
Yep.

The enzymes papain and pepsin cut antibodies. If you coated your fingertips with these they could effectively cut the detecting half of the antibody (antigen recognizing portion) away from the portion with the attached dye. This would ruin the test.

An just so you know, the molecule that an antibody recognizes is called its "Epitope"

Does pepsin even exist in high quantities outside of the stomach?

Yay more stuff for governments to waste money on! It will never ever ever pay for it's self, you are just going to further push it underground and then the chemists will figure out an additive to put in the drugs to bypass it... when will they learn.
Decriminalize,tax and control... I would rather know who is doing what so if it does become a problem you have better tools available to deal with it. Forcing people to deny who they really are because they need to hide and lie about who they really are is not the answer it's creating another problem.
It's a form of discrimination, and all of you un-educated bubble boys who think every drug is crack need to stop talking.
