MaddDog: If your that serious about it then check this out. Some of the shit said above will work, some better then others but choosing one will be the hard part. If your willing to spend a good chunk of money you can pretty much be guarenteed a clean test. Go to your nearest GNC store and ask them for the drink that cleans out your system. They more then likely keep it in some locked glass case inside the store, they will take you to it and retrieve a bottle. First off, the cleaner costs around $40 for a single use. I know the last thing you want to do is spend $40 on a single, one time only drink to clean out your system and it not work. I don't remember the exact name of the drink but the company that manufacture's them guarentee's the drink will work, or double your money back. I know $80 isnt worth a job, but it's mainly to reasure you it will work (you think a company would offer that to the thousands of people taking it if they knew it wouldn't work). Now there is a catch to this. The drink doesn't really 'clean out your system', in so many words it just covers the weed from showing up on a drug test temporarily. Im not sure the guidelines to taking it, but it lasts for aproximatley 6-8 hours. You have to use it just a couple of hours before your test. I know this sounds like a hassle, but you have to decide weather or not you think its worth it. I can't tell you from a personal standpoint if it works or not; I had to see my probation officer for the first time since getting arrested (weed/alcohol related) and so I drank a bottle, and didn't get tested. I can tell you this, when I asked the lady that worked at GNC, she said it was a very popular drink and she has customers that get tested on a regular basis and had never failed a single one of them. Of course there's the alternative in drinking a shitload of whatever the fuck will make you piss and that will probably work, but I wouldnt risk it. This cleaner also comes in a pill format that works just the same, same price, single use. Good luck with your job.
