Harris teeter drug test???

Has anyone ever worked at Harris teeter in NC, and when did they drug test you? Because I work there now but I haven't been put on the floor bc I'm still doing my computer training which I only have 4more left to do and I'm scared they will drug test me soon. Please help me. (And please don't judge me or tell me to stop bc everyone has a reason for everything and I've been through a lot and I don't need to bad commits. I just want to do what makes me happy without judgement).
