Re-Phrasing Question

I have accepted an Area Manager position and I have a drug test in a month. As a user of THC for a few years, I was wondering what is expected for a pre-employment drug test. I am currently in a legal state, moving to work in a state where it is illegal. Obviously, I have and never would use on the job or anything of that nature, I’m just curious for what the procedure is for the pre-employment test. Do they test for it?
