1. When was the last time you smoked, how often do you smoke, and how much ? Also your weight and are you lean or fat?
2. When is the test?
3. Is it on the spot or sent to a lab?
4. Where do you have to do it at?
Possible Solutions for on the spot testing:
1. If you don't have someone in the room while you do it. Have someone with the same gender as you that does't do drugs piss in a bag and tie it off then keep it on you in a place where you can keep the temp of the piss between 91F and 97F degrees (Useully between your legs works best).
2. This is kinda gross but works as well. keep a little bit of bleach with you when you go. dip your finger in the bleach to the first line on your finger about 10mins til you take the test so it can dry. Then you pee on the finger that has the bleach.
3. If your lean, occassional smoker, and have about a week. Drink 3 cans of AMP, two 16oz Cranberry Juices, and eat one big of doritos. Also exericse until you are sweaty as hell. Do this every day until the day of the drop.
4. Go to a tanning salon and find a lotion with THC in it. Then you can say that its false positive.
5. You can dilute your sample heavily with water. Don't confuse this with drinking water; you can also add water directly to the sample. Be sure to use hot water (between 91 and 97 degrees), they will likely take the temperature of the sample. This method isn't dependable because some facilities have the sink water shut off so people can't do this. If there is running water, they may listen to you. If you turn on the water, make it sound like you're washing your hands or something.
I have personally used the first 4 methods while on probation and parole and they worked for me.
Also my friend uses this site for reference for medicines that will give false postives and what it will give the false positive for. He said it really does work and he is a major addict. False Positives on Drug Tests
honestly if you can fake a false positve. They will have you wait so long pending on what you showed a false positive for. Then have you redo the test. This works best if its going to be sent to a lab.
