Re: IMPORTANT!!! help me 
Okay, as someone who's been in your shoes let me share this with you. And please understand that I do not mean to sound cruel here.
THC is a fat soluble compound and your body stores it in your fat cells. Which means there is no way to clean out your system "fast". There are people out there selling cleansing kits, but these are simply masking agents and most drug testing companies use methods which will pick up these masking chemicals and your test will be nullified. Meaning you fail. These very same people will guarantee you results but they are simply selling their product. They could care less if you pass of fail. All they want is your money.
Years ago I was in a situation where I had already changed jobs and was suddenly made aware that I would be UA'ed before I could go on the payroll. At the time I was a daily toker. I was lucky in that a friend of mine was in high places at this company and he arranged for me to delay my UA. I stopped cold turkey and drank lots of water and after a month I self-tested using a kit from a local head shop. The results were positive. A month later same results. I finally went on a crash course drinking 1 gallon of distilled water and 1 gallon of cranberry juice each day for a whole week. That crash course is a lot easier to write about than to carry it out. Drinking 2 gallons of anything in a 12 hour period, while you're awake, is not simple. And you're going to have to piss about every 10-15 minutes while you're awake. Something not easily handled in certain jobs. Again i was lucky and had a job where no one suspected anything. Going to the bathroom 4-5 time an hour will make some people suspicious of your actions. This crash course worked because at the end of the week I took another self-test and passed. I then went and took my official UA for this company and all was well. They never tested me again. But a few years ago I was working for a company which randomly tested all it's employees each month. I was in abstinence at the time so no problem.
Again, not to be cruel, but you're probably SOL unless you can sneak some clean urine into the test. And in some places this is impossible because one of the tests I was given, the clinical person insisted on watching me and it was a woman no less. They also check for temperature of the urine and if it's not in range, then you fail.
The only advice I can offer is to go to this person, company, agency, whatever, unless it's Law Enforcement and you're doing this for your PO, and come clean. Tell them you will be glad to take the test but you know now it will be positive for canabiniods. They may offer you help in the form of time, or rehab classes. Or you can tell them to take a hike. It's your choice and up there's if they don't like it.
I for one will be glad when the day finally comes that employers are not allowed to discriminate against people who use a relatively harmless compound like MJ. I can see a person losing their job because they piss hot and the same people who fired them for this infraction routinely consume alcohol...which is far more dangerous than weed.
I wish you the best. And at 24, you're still young enough to move on to another job if this doesn't work out for you. But you're really better off working for some place which doesn't practice the hypocrisy which is so prevalent in our world.
