Drug Testing Information |
What Do They Test For?- Cannabinoids (marijuana, hash)
- Cocaine (cocaine, crack, benzoylecognine)
- Amphetamines (amphetamines, methamphetamines, speed)
- Opiates (heroin, opium, codeine, morphine)
- Phencyclidine (PCP)
|  | What Are the Types of Drug Tests?
There are four primary types of drug sample: urine, hair, saliva, and blood. Most common is the urine test which has the benefit of being inexpensive and less intrusive than the blood test. | | Urine Tests
- Are the least expensive of the test methods
- Can be done at home (for example by parents)
- Detect use primarily within the past week (longer with regular use)
- Can be affected by abstaining from use for a period of time before the test
- Are often temperature tested to insure sample integrity
| | Hair Tests
- Are considered the least intrusive method of drug testing
- Are currently many times more expensive than urine tests
- Detects substance use over a longer period
- Do not usually detect use within the past week
- Requires a sample of hair about the diameter of a pencil and 1.5 inches long - test cannot be done with a single hair
- Test positive a little more than twice as often as a urine test
- Are not significantly affected by brief periods of abstinence from drugs
- Can sometimes be used to determine when use occured and if it has been discontinued
- Claims to be able to reliably differentiate between opiate and poppy seed use
| | Saliva Tests
- Can be done at home (for example by parents)
- Detect use primarily within the past week (longer with regular use)
- Can be affected by abstaining from use for a period of time before the test
| | Blood Tests
- Are considered the most intrusive method of testing
- Are the most expensive method of testing
- Are the most accurate method of testing
- Are the least common method of testing (most likely due to cost)
| | Detection Periods
The amount of time any drug can be detected in one's system can vary from person to person and test to test. It certainly can also depend on the amount of the drug taken and when it was taken relative to the time of the test. Keeping in mind that there is no 100% hard and fast rule for how long a drug will be in one's system, listed below are some general guidelines on the drug test detection time for various drugs. | | Approximate Detection Time in Urine
- Alcohol 1-2 days
- Amphetamines (crystal, Ice, crank, methamphetamines) 5-7 days
- Barbituates Short-Acting (ie. secobarbital) 1-2 days
- Barbituates Long-Acting (ie. phenobarbital) 2-3 weeks
- Benzodiazepines (Librium®,Valium®,Serax,Xanax®) 2-30 days
- Cannabinoids (THC,Marijuana) 20-90 days
- Clenbuterol 2-4 days
- Cocaine (Crack) 3-5 days
- Codeine 2-5 days
- Euphorics (MDMA, Ecstasy) 3-7 days
- LSD 1-4 days
- Methadone 3-5 days
- Methaqualone (Quaalude) l-14 days
- Opiates (heroin, Vicode, morphine, codeine) 2-7 days
- Phencyclidine (PCP, Angel Dust) 1-30 days
- Phenobarbital 10-20 days
- Propoxyphene (Darvon) 1-3 days
- Psilocybin (mushrooms) 3-5
- Steroids (anabolic) oral 14 days
| | False Positives
False positive test results can be attributed to human error and sample contamination. In addition, there are a number of controlled and uncontrolled substances that will cause a false positive result; these are some of the reasons why labs will immediately split your specimen into two samples.
