I am the mum of a soldier who has failed a CDT. I understand how you all feel about this as i can't stand drugs myself. My son is learning a very hard lesson and quite rightly so. My question for you is, how long does it take from first learning you have failed the test to getting discharged. Any help greatly appreciated as this has been going on for what seems like ages now and i can't find the information on google. Thanks to anyone who responds.
