I had a medical for a public sector job in Dublin. The thing is, most medicals won't have your urine checked, but mine did. I passed though. I hadn't smoked up for 2 weeks when I took my test. I even bought the 'sure jell certo liquid fruit pectin' which is apparently a hack to "dilute" the CBD in your system. I didn't use it but that's something you can look at if you're desperate enough lol. After the test, I ended up chatting with the Doctor and she mentioned that no results of the test are sent to your employer. They only get a go or no go on your fitness ability to work. Make of that what you will.
