And everyone metabolises at a slightly different rate and will have there own under the inference time. As you yourself have already stated.
It is not an exact science, again if it was I would agree with you.
For my own information, given that individuals will break down and deal with different drugs in different rates, how exactly do you find out how long it has been since a particular person was under the influence?
Data from journals gives you the relevant percentile data for user groups.
Your argument for this seems to be very weak, going by your logic that they may have been under the influence means you have to fire everyone because they may have taken a short acting drug at work or one that you cannot detect, someone who has a trace of thc in their system is about as much a risk of harming someone as anyone else.
