During a job interview, have you ever been asked to piss for your new employer? New applicants for many of the Fortune 500 corporations are now being forced to take a drug test. In fact, 15 million will be tested this year. Drug byproducts can be detected in urine, blood, hair, external residue, and even perspiration! Drugs aren't the only things they test for; employers are using urinalysis to test women for pregnancy. Pregnant women are getting laid off or denied employment after taking such a test. Parents are spying on their children. The DOD Directive requires the military to screen all active duty members annually. If you don't want to be a victim of the drug war, this text will help you. If you are well known, this text may protect your reputation. I strongly recommended that drug users (pot smokers in particular) read this.

Detection times vary depending on analytical method used, drug metabolism, tolerance, patient's condition, fluid intake and method and frequency of ingestion.

Other factors determining degree of intoxication include metabolism, tolerance, frequency of intake, fluid intake, amount of marijuana, potency of marijuana, and length of time you've been a user. If you use marijuana on rare occasions, your urine may be clean of metabolites in less than a week. There is a common and strange phenomena that occurs with chronic users. You would expect a chronic user to have the longest detection time and the smallest chance of passing. This is not always the case. A chronic user with a high tolerance will eliminate drugs quicker than an occasional user. Chronic users have tested negative after a week long binge. Lipid tissue also makes a huge difference. Skinny users not only have a faster metabolism (usually), but also lack storage for THC metabolites. Fat will cause a lag in excretion pattern, and lead to a longer detection time. You should now be able to understand why an individuals detection time for THC is so unpredictable.

Positive (defined): 50 nanograms of THC metabolites per milliliter defines a "presumptive positive" by NIDA certified labs. This value was originally 20 ng/mL, but too many false positives resulted. So the level was raised to 100 ng/mL to reduce false positives. As of January 1995, the threshold was lowered back down to 50 ng/mL because drinking water would easily bring a positive below 100 ng. Be aware that these cutoffs are not universally consistent.

Drink at least eight hefty glasses of fluid (preferably water) just prior to the test. Many people start drinking water several days before the test; which is useless. Water does NOT clean any THC metabolites out of your system because THC is not water soluble. Water only dilutes urine temporarily. Do not over do it; you can get water intoxication. People can actually overdose and even die from water intoxication. It's very hard to do, and you'll vomit before anything gets serious.

Eating red meat will boost creatinine levels. If you eat a lot of red meat for the 3 days prior to the test, your creatinine level will be normal, and the lab won't know that you've diluted your urine sample.
