Hi I applied for my licence April 2021 after been revoked 6 monthes for cannabis use. A letter arrived from dvla medical group on the 31st December 8 monthes later. Problem is I never actually thought they were going to bother getting back to me I couldn’t get ahold of them for 5 monthes straight while I was off cannabis and clean and in the end ended up relapsing I’ve been smoking again for a good few monthes I figured I stop after the new year and detox again in time but the letter has caught me off guard. Does anybody know the time frames roughly from when there first letter is sent out to when I have to take a urine test? I’m an idiot I know and I’ve made a stupid decision. Any help is much appreciated thanks.
