| Comment | Have you known people before to have been tested? The article said only 500 officers had been trained in the use of the testing kit. That's for the whole of police scotland, so it's unlikely for anyone you know to have been tested.
I wonder about the sensitivity of the tests when it comes to cannabis especially. Does it reasonably distinguish from people who must be high at the time of testing and those who had some the night before, for example? |
