I would bet that you are OK. If you have enough time you can order some test strips off the internet and test yourself or go to your local drug store chain or wal mart and purchse a home test kit, it will be about $15-20.00. Def. cheaper on line. Testing yourself is the only way to know. If you test negative with your morning void you should be OK for the drug screen. Remember that everyone rids themselves of THC metabolites at diff. rates so you need to test yourself or else you are going into the drug screen with just hope on your side. Good Luck.
