A test like will have very low sensitivity, being unable to detect most adulterants added to drinks, and low specificity as well, given that colorimetry is a bad way to detect a substance which differs more by specific gravity than color, and given that drinks are seldom clear to begin with.
A false positive could have unfortunate social outcomes for everyone involved, a false negative would create unwarranted confidence, spiked drinks are uncommon enough that it's a safe bet that false one or the other would be the normal outcome, and the damned thing is, the cup is known to already contain the most common date rape drug in existence, ethanol.

Alright.
