I disagree as they have been using the scraper for a few years.. the problem with the scraper is that in only indicates a presence in ur saliva but NOT a specific reading of level of the or whatever it looks for, that’s why they are not used elsewhere other than Australia.. cops don’t care if u are stoned or not, all they care about is if it’s in ur system... all is pretty much does is indicate wether u have had some or not, nothing like alcohol brathaliser...
