There are a few things that can cause a false positive:\n· Kidney infection and diabetes can cause you to test positive for cocaine.\nDesipramine and amantadine, prescribed to reduce cravings for cocaine, may cause false-positive results on urine tests for amphetamines.\n\nHave your doctor test your blood or hair samples.

Absolutely. A good friend of mine passed every drug screen he ever took. Even when they surprised him with an unannounced drug test he was able to pass it. All you have to do is dont do drugs!

No. They stay in you system approx 3 days. The high from smoking vs. snorting is dramatically different. Cocaine itself is very addictive, it is an expensive high and last quite a while. While crack is cheaper, but its' affect goes away in minutes rather than hours. I say no to drugs- sober about 8 yrs.  Shooting and smoking are more addictive than snorting.

There have been no reports of this product causing a false positive drug screen.\n\nDrug screening processes have grown more sophisticated. They don't test for remnants of chemical byproducts in the system anymore. They now test for traces of the drug itself. We get people in our police dept all the time who fail a drug test but say "I just took some Sudafed." The response is "Cool. We don't test for Sudafed. We test for methamphetamine. You failed."

Standardly Detectable in Urine for 48-72 hours after use.\n\n"Elimination of cocaine is predominantly controlled by its biotranformation. Very low concentrations of cocaine may be detected in urine during the initial several hours, but benzoylegonine persists in urine at detectable concentrations for 48 hrs."\n\nLong term habitual users may have traces of cocaine remain in their system for longer than the standard 3 days.\n\nIn hair tests, it can be detected at different variables, depending on your metabolism.  Increasing doses usually result in increased levels of the drug and metabolites in hair.

That's something you shouldn't know because you shouldn't be doing cocaine in the first place. It's dangerous!!!!!!!!!!!!!!!!!!!

Any Cocaine Metabolite stays in your body system for a minimum of 1.25- 4 hours and a maximum of 2-3 days.This is called the detection time.You can metabolize drugs at a different rate and, thus, have slightly different maximum and minimum detection times, as to how long the drug will stay in the body.

1.3.1 Passive smoke and positives: \n"Second hand marijuana smoke in a car can cause you to fail the next day" (Nightbyrd). It is possible that second hand [marijuana] smoke will raise someone to the 50 ng/mL level; however, *extreme* exposure is required. For instance, a closed car full of pot smokers and a non-smoker may render the non-smoker positive for both urinalysis and the hair test, provided that they are sealed in the car for a while. The Army did a case study where volunteers were put in a room pumped full of smoke for an hour, five time daily. Subjects started testing positive after the second day. The non-smoker would have to take in virtually as much second hand smoke as a smoker. Non-smokers are safe in a ventilated area, as long as they don't get a hair test. According to Clinton, simply blowing crack smoke on ones hair may cause a positive hair test. Second hand pot smoke doesn't affect the hair test results as much as crack smoke does mainly because exhaled smoke contains no THC. The only pot smoke that contains THC is the smoke that hasn't entered the lungs.

I knew some people in the Air Force who tested positive for drugs. First, he needs to get a military lawyer. He will suggest a hair sample test for the drug. However, if you are guilty of doing drugs, they will have to put you through a rehab program before you are dishonorable discharged.

You don't fail per se, but it can come back inconclusive and you'll have to repeat the test.  \n\nThe presence of Drugs is what makes you fail.  Unless you have cocaine in your water supply, just take the test again and don't worry about it.

Depends on whether or not you are a chronic user.  If you used frequently and for a long period of time, it may show up in hair follicle tests for upwards of 60 days.\n\nHowever, occasional users will test positive for marijuana use with conventional urine tests for between 14 and 30 days.  The less frequent the use, the shorter the time.

You can't.  It will test positive in your urine for over a month if you have been smoking for a long time.  It will test positive in a hair follicle for 3-6 months, depending on how long/how much you've used.\n\nOvernight?  Absolutely no way.  There's nothing you can drink, eat or do to get it out overnight...or two nights...or three nights...or

They send you to a lab to do the test.  It test for everything from cocaine, to pot, to prescription drugs such as vicodin.  Basically ANY kind of drug that is in your system will be found during this drug test...so even if you're taking a prescription drug, be prepared to explain why it's in your system.  I know this because when I tried to get on at Albertsons, when I took my drug test I had vicoding in my system..from a prescription...but since I couldn't find my prescription bottle they refused to hire me.  So..just be prepared..EVERYTHING that is considered a drug whether legal, illegal, prescription or over the counter will show up when they do the test
