You can test for nicotine usage very easily, but you can’t catch someone smoking anywhere near as easily.

- goldcd 7y agoIt'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.
- shhwwreyfd 7y agoThey would not be without smoke for weeks, not even for hours. Smokers continuously need cigarettes and reek of tobacco.
- 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.
