Drug and alcohol abuse causes different side effects on the human body. For example, stimulants such as cocaine and methamphetamine (also known as meth, speed, or ice) cause a constriction of the body’s blood vessels along with increased heart rate. In those individuals that are more pre-disposed to illness, these two effects together can result in stroke and cardiac arrhythmias.
The time it takes to get the results of a drug test varies based on the reason for the test (for example, if it’s for an emergency or employment screening) and the type of drug test. Be sure to tell the testing professional if you are taking any prescription drugs, over-the-counter medicines, or supplements, because these substances may affect your test results. Also, you should avoid foods with poppy seeds, which can show up as opiates in a drug test. They then measure the temperature of the urine sample to make sure it is suitable for testing.
- Once the high and euphoria are over, the user wants and needs more cocaine to feel better.
- Upon transport, the CCF is again updated as it is received by the testing laboratory.
- For example, consuming high enough quantities of dextromethorphan, a common ingredient in cough syrups, can cause a positive result for PCP on this type of test.

When Whitney Houston died at the early age of 48, the medical examiner found cocaine and heart disease caused her death. Corey Haim died from a cocaine overdose at the young age of 38 in 2010. When the laboratory discovers a “fatal flaw” during its processing of alcohol and opiates incoming specimens the laboratory will report that the specimen has been “Rejected for Testing” (with the reason stated). Methadone is another CNS depressant known to cause disorientation, weakness, drowsiness, light-headedness and visual impairment [26,27].
DOT Urine Specimen Collector Training Correctable and Fatal Flaws
This began with the introduction of several new drugs such as heroin, 3,4-methylenedioxymethamphetamine (MDMA), lysergic acid diethylamide (LSD), and γ-hydroxybutyric acid (GHB). Toxicology laboratories previously focused on a rather narrow range of compounds, including amphetamines, cocaine, selling prescription drugs illegally opioids, cannabinoids, salicylate, antidepressants and acetaminophen. Now, potent fentanyl derivatives are mixed with heroin or used on their own and could kill drug users very quickly. Immunoassays, the most common type of urine drug screening, don’t measure drugs themselves.
What is Cocaine?
Cocaine is a powerful stimulant drug that is illegal in most countries and is commonly abused. How long cocaine stays in the system is not the same for each user. There are determining factors such as frequency of use, the amount ingested, body weight, metabolism, and the type of cocaine drug test. A single use can be detected with urine for 2 – 5 days with a urine drug test for cocaine whereas this single use might not be detected with a hair cocaine drug test. It is difficult to analyze certain drugs by GC-MS techniques, such as those that are present in low concentrations. Furthermore, low recovery substances can be identified with this instrument.
The Importance of Employer Drug Testing
The procedure of dried blood spot analysis (reproduced with permission from Elsevier [36]). Blood matrix can be easily collected using a finger prick; blood can be easily withdrawn on site by the police/the driver. Dried blood spots/dried serum spots could be used instead of venepuncture blood collection at the hospital, as it is cheaper and more accessible (Figure 18) [36].

Drug and alcohol rehabilitation programs may request urine drug screens at initial assessments and follow-up appointments. Signs of drug use can remain in a person’s system long after the physical effects wear off. The analysis can determine whether a person used specific drugs days or weeks before testing.
Drug testing may be done in a variety of locations, including labs, hospitals, drug treatment centers, and workplaces. The most commonly used drug tests require that you give a urine sample. To minimize the risk of false positives, urine drug screens have cut-off levels. This means that a result is only positive when the test detects an amount of a drug that is above a certain level. Cut-offs also reduce the likelihood of testing positive due to only passive exposure to a drug. A doctor may request a urine drug screen if they think that a person has been using illegal drugs or misusing prescription drugs.
Specimen Requirements
A 10-panel drug test will look for 10 of the most common drugs that a person may be abusing. This selection usually includes five common prescription medications and five illicit street drugs. The tests are simple to administer and take and are widely available. Similar tests are popular for testing potential employees, though a simpler 4- or 5-panel drug test with alcohol is more common. It is a metabolite of cocaine and it can be detected in a person’s urine for up to three days after the drug is taken.
Apart from having a wide-mouthed sterile cup, each sterile cup has a temperature strip to protect from urine contamination. The sterile cup has a maximum capacity of 90 mL, enough to be used for testing. These features make this an optimal urine testing cup that will yield accurate test results. Most people will opt for a multi-drug screen kit like the 12 Panel DrugConfirm Advanced Flat Panel Urine Drug Test Cup with Adulterants. A multi-drug test kit can save time because it detects several substances at once. The person being tested must urinate into the sample cup to the appropriate volume needed for testing.
A false-negative result can occur when urine is very diluted, for example. A GC-MS test is more reliable than an IA test, and it can detect more substances. This is more common in workplaces that require high levels of safety. For example, United States federal law mandates that people working in the transportation industry take regular drug tests.
Ensuring that the sample is in this temperature range is the best way to tell whether the sample actually came from the donor at the time of testing. If the specimen temperatures go lower or higher than this range, the urine test was likely tampered with or contaminated. If this is the case, the sample will be rejected and the donor may be subject to consequences and another drug test. Medical staff will often measure the temperature of urine samples that are submitted to them. The appearance of a sample specimen is not nearly enough to verify that the sample submitted is authentic and unadulterated. Though the sample may look authentic, donor’s potentially could have used another persons urine that they snuck into the testing facility.
The side effects of the use of cannabinoids vary from loss of memory, problems with cognition, and even lung cancer in those that use it frequently [18]. Drug users who inject and partake in these drugs to engage in thoughtless sexual activity are at a higher risk of attaining sexually transmitted or blood-borne infections or both. Some of these infections can be fatal, including HIV, AIDS, hepatitis, herpes, endocarditis, and other sexually transmitted diseases. From this, we can say that police controls on the roadside are for the benefit of maintaining public health (as well as transgression) [13,16]. A drug test involves testing a biological sample, such as urine or hair, for the presence of a legal or illegal drug. There are several possible uses for a drug test, the most common of which is for pre-employment screening.
The appearance of the sample may also not indicate whether the donor put soap, water, or other substances into the specimen to create an invalid result. Therefore, the medical staff makes use of an adulterant test using temperature to determine if the samples have been tampered with. 10-panel drug tests can effectively test for 10 substances within their own window of detection.
Sample collection and pre-treatment are used to make the extract ready for use in the testing devices. There are many roadside testing devices available for the quick screening of samples. This article will help law enforcement agencies to evaluate all of these devices in one place and decide which device is suitable for their needs. There are many pros and cons of the devices discussed in this paper. Screening is followed by new and emerging confirmatory devices to confirm the presence of illicit drugs.
