I first saw Consumer Physics' SCiO handheld scanner a couple of years ago and was impressed by its ability to identify materials by scanning and analyzing their chemical composition. In the intervening years, Consumer Physics has partnered with Analog Devices to increase the sensor's accuracy and reduce its size, and at CES 2017, the company announced the first smartphone with an integrated SCiO sensor, making this technology even easier to carry and use.
[...] The SCiO sensor uses near-infrared spectroscopy to identify a material's molecular content. By illuminating an object with a broadband light source and using the spectrometer, a type of optical sensor, to break the reflected light into its constituent components, SCiO's signal processing algorithms compare the reflected light's wavelengths to the original emission to create a spectral fingerprint. This technique works because molecules will only absorb photons at certain energy levels, which means specific wavelengths will be missing or attenuated in the reflected light.

Expect metal detectors to be augmented with drug sensors, to be mandated at every public building, and to be integrated into theft detectors at every corporate chain store and franchise. Within a year, drug possession will be totally eliminated by chemical sensors everywhere, just like graffiti was totally eliminated by surveillance cameras everywhere.
With no freedoms remaining in the real world, expect lots more online trolling. Tweenage terrorist lesbian niggers rule the universe!
