Having something like this accessible to harm reduction groups could save a lot of lives lost due to fentanyl overdose, which is currently epidemic in North America. On the other hand, groups switching to this method from traditional chemical reagent tests would basically be building evidence for the police to use against them by creating digital records of exactly what chemicals they had in their possession (even briefly) and when. Legally, posession is posession, even if you're at a festival trying to save some kid from OD.
