I would try yo get a letter from the program that you are in. For example if Maritime Consortium runs your company drug test program you should ask them for it.
Another option is take a drug test and give the results or if you have a drug test thats wa s done in the last 6 months I think you can use that. ( double check that last part, not sure)
Go to the CG checklist website for your upgrade to 2M.
