Detecting the THC molecule in room air

  1. Dec 17, 2013 #1
    Is there a material or chemical substance that would have a visable change of any kind when exposed to THC? For example-something I can put in a room and detect if anyone is smoking pot in that area?

    Welcome to the PF.

    It looks like there are lots of test kits for saliva and so on:

    But I'm not sure what the best way would be for airborne testing. Does the room have a central air heating/conditioning unit feeding it? If so, you might be able to test the particulates caught by the filter...

    Most people use the Mark I Mod 0 Nasal Atmospheric Delivery System and Olfactory Sampling Device, or their nose.

    The US border control and police have a device that can accurately detect trace amounts of drugs by sampling the air, and signals detection with a visible change. The device is a dog.
