It's pretty easy to test for Carbon Monoxide - can use a small handheld device that looks like a breathalyzer.

- peteretep 7y agoYou still need to be physically present at the time of smoking though, rather than able to spot check weeks afterwards like you can with nicotine usage in general.

- rsynnott 7y agoCO-related effects persist in smokers for some time after smoking (a few days for red blood cell weirdness to go away, IIRC). Not sure how easy to test it is, though.
