Does FedEx Drug Test for Part time?

Hey so upcoming I have a meeting at the recruiter center and I was wondering do they actually test or do they care for things like weed? I heard from other place they don't for part time but ykkk kinda worried as I take almost 5-6 grams in edibles per day for medical reasons and so like within that reasoning if they drug test me when they hand it to me should I just tell them "like I'm gonna fail this for weed but I wanted to let you know that I will never bring it into the workplace and my medical team agreed it is beneficial to me and I am getting legal cannabinoids". Or something like, "I need advice, please?
