Cocaine Drug Test for HOUSE ARREST PLEASE HELP

[jooked]

hi, i have a question about a retarded ass mistake that a good friend of mine made last night because of new years.......he lives in las vegas, he is currently on a house arrest program and he has a weekly drug test every thursday, he has been completely clean since beginning the program, however last night being new years eve and the peer pressure of an ex girlfriend, he made a huge mistake and used a very insignificant amount of cocaine...maybe a little under a half of a gram.. he has not used in probably a month and the last time he did, it was another small amount such as this time.... he works out regularly, drinks plenty of water, and is taking niacin and cranberry supplements to help flush it out of his system..also he just found out all of his charges have been dropped and he will be completely free after january 10th so he DESPERATELY cannot afford to have this test on thursday go badly for him.. he has not had one bad test and this is the one that could really screw him over being so close to his release / clean slate...if his test is on thursday morning (8 am PST) and it is tuesday (5 pm PST) currently what would you recommend for him and any tips/comments/suggestions would be more than appreciated. please get back to me as soon as possible.

thank you so much for your time in advance.
