Just got news that made my day!!

So, I made a post a few days ago thinking that I had to take an actual "piss-in-a-cup" drug test. In actuality no urine will be involved. I have to take a "Drug Evaluation" test. Basically, a sit down meeting with a drug counselor to determine if I have a drug problem. Now, I'm pretty ecstatic about this. But also still a bit nervous. What can I expect from this evaluation? Just questions about prior/ current drug usage I'm guessing?

Anyone with experience in this please advice?
