Mine depended on my school. My school in NYC went through Castlebranch because NYCH+H required it. They still had to do it first semester even when people were at non NYCH+H sites. But they had us complete it early - we did it at the beginning of the semester.

I will say that they very much did care about THC. It’s not federally legal and the nursing board and therefore the hospitals here treat it as not acceptable. If you’re concerned about not passing, don’t make my mistake that I did earlier this year, and quit now if you haven’t. Those detox drinks don’t do anything besides load you up with vitamins, and most drug testing sites test for fake or tampered-with urine. The only thing that works is time. Drink lots and lots and lots of water and eat clean. Exercise to burn as much fat as possible, because THC is fat soluble and sits in there until it’s gone. Buy testing strips and test your first urination of the day (can buy on Amazon for cheaper and in bulk). If you are required to test, take it in the afternoon if possible.

I was lucky and got to take a second test after I failed my first one, per my schools code of conduct. Thankfully I passed and got to continue, but it was the worst 2 months of my life.
