If it's for a job, they can't observe you. Pick up some Quick Fix, practice everything, and you're good to go.

Also, drinking lots of water and all that other junk does virtually nothing days before a test (you can dilute hours before, this is different). All you can do to speed the removal of THC and it's metabolites from your system is exercise (burning fat), but with 4 days, the THC would not have enough time to leave your blood stream.

Read up on subbing, you should be golden. :thumbsup:
