Hiring process

So I’m in the very early stages of the hiring process (just submitted an application and will be attending a seminar next week where I’ll be completing the multiple choice test as well). I also want to be fast tracked as I am eager to get started ASAP. I am more so curious about the drug test portion of the process, I use THC gummies most nights to help me with my insomnia which I am ready to give up to comply with department requirements, but am wondering if the drug test needs to be completely clean to advance? Any answers or insight would be greatly appreciated!
