Can your THC levels go down if you havent smoked in two weeks but smoked constantly before?

Yes, the levels will start to decay as you eliminate fat from your system over time. It depends on how much you smoke, how much fat you have, your metabolic rate, and the strength of the weed to determine if it is completely gone. They sell a home test for drug teting at CVS and they work real well. If you need to know, the kit is about $40 and it will tell you if it is still there.

There is a way to pass a drug test ,but its not very comfortable. First, lets cover some background. In most cases, the evidence they are testing for is sotred in your fat and released slowly in to your blood stream over time. The longer you go without, the more likely you will pass the test. So the byproducts of drug use are tranported out of the body in your urine (and feces, there is a neat test!). So you need to "clean" your urine.

So what you can do is injest a bunch of sugar, with lots of water. About an hour or two before the test, you have to injest 1/3 of a cup of sugar with 16 ounces of water. Wait 15 minutes and drink another 16 ounces of water and then start trying to pee. You should also take some creatin and some vitamin B2. The creatin is a marker they check for to make sure you have not dilluted the sample (which you are). The B2 makes your pee yellow so it "looks" right. If you weigh more than 150 pounds, you should double up on the recipe. The sugar shocks your body in to not releasing anything in your urine for a brief period, so you pee clean, and the creatin and B2 make your pee look correct.

You should do this about an hour before the test, and it last for about 1.5 to 3 hours after it is working. One way I checked to see if it was working was when the B2 made my pee super yellow. You can buy a test kit at CVS that checks for specific drugs, and these tests are very sensitive. So you can pretest to see if it is working, however they are about $40.

So before the test, you should try to get rid of your fat by wqorking out. But don't work out two days before the test, because as stated earlier, you get rid of it through your pee. So if you work out hard, you might relase more, so relax the days before the test. You also want to avoid fatty or greasy foods in the days up to the test, and avoid alcohol, caffiene, pop, and fruit juice the day of and the day before the test.

You can pass a urine test ,but Its not comfortable; your bladder will want to explode, the creatin made my face real hot, and the sugar shocks your body and its an unpleasent expeirence no matter how you slice it. But I can tell you with certainty that this works. I was testing positive with the home test the day before I took the test, and in fact that was how I learned that I needed to do a double dose. The day of the test, I was not sure it was working, but right before the test, my pee looked like a highlighter, and that's when I felt pretty sure it was safe. And I passed the test. So it can work.
