EMIT Dip Strips

Hey, I was wondering what kind of vulnerabilities the crappy dip strip panel tests have. From what I can tell they don't test for PH or Nitrates, but I could be wrong. I'm looking for an easier way to beat these than substitution.
These things are far from high tech so it can't be that hard to beat them.

It could be either way.

Some drug testing kits feature additional "validity check" panels that test pH and nitrites, while others are strictly drug assays that can test anywhere from 5 and up to 12 types of drugs.


It all depends on what was ordered by the party thats paying for the test.
