Because of the steady rise in the use of e-cigarettes that burn nicotine and cannabis oil, new detectors are being installed in places where smoking and vaping are prohibited, such as schools and universities. They have particularly caught on with school districts, where administrators and teachers are trying to stem the rising tide of popularity of vaping amongst teenagers.

Vaping is much more complicated to detect than burning tobacco or marijuana. These detectors are powered by batteries that heat a liquid and turn it into vapor that is inhaled. The vapor usually contains nicotine, CBD, or THC.

The US federal government recently issued several regulations banning flavored disposable vapes and pods because it is believed they are marketed to children. However, these products are still easy to buy, as cheap Chinese flavored pods and disposables are still entering the United States.
