Drug Screening - Wcccd

Hello,

I'm already done on all of all the medical requirements. I read some of the postings and some said that drug test is also a requirement. This was not stated on the letter that I received. I don't know if I'll be able to submit the result on orientation day and I think the result will come out at about 2 -3 days. Is it really necessary to have that on orientation day? or can I submit it after that? Thanks.
