Thin Layer Chromatography In Drug Screening

Drug testing in the United States began with the explosive use of illegal drugs, in order to curb drug abuse. This began during the Vietnam War with drug use at a climax. In general, Drug testing is a way to detect illegal drug use and deter it, usually by Urinalysis. Drug testing in the United States violates a citizen's right to unreasonable search and seizure's along with jeopardizing one's freedom. Furthermore, Drug testing is not only an unreliable invasion of a person's privacy but it assumes that one is guilty before submitting to the test.

| Analysis of urine by physical, chemical, microscopical means to test for the presence of disease drug.

drug testing has become very common in both the workplace and schools within the last twenty years or so. generally, urine testing is the most common form of drug screening. many people are creative in their efforts to beat drug tests and have formulated many products to mask the appearance of drugs in the system. products such as masking chemicals and even synthetic urine are widely available, and even the most severe cases of drug abuse may go undetected. because of the ever-expanding market of products designed to help a drug user pass a screening, many employers are turning to hair follicle drug testing.

Eric, I found your point about standardizing drug screening for pregnant mothers interesting. In my opinion testing for drugs could be a beneficial preventative strategy. Testing for alcohol use early on can prevent damage to the fetus. Also, testing will allow mothers the opportunity to receive help. The only negative outcomes of standardizing drug screenings are the cost and doctor- patient relationship. Drug screening expecting mothers can be expensive, but the cost to care for a infit addicted to drugs is more. Drug screenings can also effect doctor- patient relationships. If drug screening were standardizing the relationship would change to doctor- patient- police relationship.

Throughout recent years, applicant drug testing has become one of the most prevalently used strategies by many organizations to control substance abuse in the workplace. Drug testing is a selection tool used by organizations to determine whether or not an individual has previously used drugs and/or alcohol. Most employers find that drug testing, if done correctly, is a worthwhile investment associated with increased workplace safety, lower absenteeism, fewer on-the-job accidents, improved productivity, lower theft rates, and less medical and workers' compensation expenses (Grondin 142). By identifying and screening out substance abusers, organizations believe that they are also screening out those

A study was released June 23, 2016, on a new method for detecting anti-depressants in whole blood by Gas Chromatography on a triple quadrupole mass spectrometry (GC-MS/MS). This study was conducted by Liliana Trua, Andre L castro, Sonia Tarelho, Pedro costa, M. GoretiF. Sales, and Helena M. Teixeira. The purpose was to use GC-MS/MS to detect and quantify antidepressants (AD) in whole blood for forensic science purposes. There is a plethora of research on the separation of AD 's from substances such as urine or serum, yet there is little research on the separation of Anti-Depressants 's from whole blood (Truta, Castro and Tarelho). Furthermore, the methods researched were generally carried out using Liquid Chromatography as opposed to Gas chromatography (Truta, Castro and Tarelho). Research has shown that Gas Chromatography produces better resolution and the analysis is faster and is measured in minutes (Cheriyadath). The objective was to determine if Gas Chromatography was truly the better method for separating whole blood from anti-depressants (Truta, Castro and Tarelho).

The use of work place drug testing has always been an issue in the law world and the corporate world. Work place drug testing is used to make sure whether the current or potential employees are not under any influence of illegal drugs on the job or during their time off of their jobs. Drug-free work programs can have a lot of short-term and long-term benefits as well as disadvantages for the employers as well as the employees.

I believe that drug testing is a useful way to ensure the safety of the workplace and the health of employees. It can lessen the impact of drug abuse in the workplace, including tardiness, absenteeism, turnover, attitude problems, theft, decreased productivity, crime and violence. No company wants to make its employees feel uncomfortable or untrustworthy, but there is also a need to make sure the environment that they work in is safe. Using pre-employment drug testing, a business can check potential candidates to make sure they comply to the safe standards of the organization without doing anything that could seem out of the blue or unnecessary.

Samantha, it does depend on where you live. The prescription pills or heroin can cost higher or cheaper than other places, depending on the access, distributor, and deals they’re having to keep an individual’s business circulating. Sometimes they offer credit until the individual get paid, rather it’s their public assistance, their paycheck, or social security check when they have had them as a client for a period of time. I’ve seen these things take place in Chicago, Illinois for a

The scientists Ms. Volk has on her team have eminent credentials in chemistry, biochemistry and biology. Today, Mrs. Volk spoke to our class about three different types of methodologies, matrices used in drug testing, and drug trends. The 1st methodology is screen methodology (instant testing) which is an immunoassay based test applied to all samples. The second step, known as the confirmation test, is usually undertaken by a laboratory using highly specific chromatographic techniques and only applied to samples that test positive during the screening test. After a suspected positive sample is detected during screening, the sample is tested using a confirmation test. Confirmation test in most laboratories is performed using mass spectrometry, and is precise but

The OTC medication chosen is NiteTime Server, this is a genetic brand pain and fever reliever. It tells what symptoms it relieves such as headache, fever, sour throat, minor aches and pains. The product has as its active ingredient both 650 mg of Acetaminophen for pain reduction and fever reducer. It also has 20 mg of Dextromethorphan HBr which is a cough suppressant. The label clearly defines what the active ingredients do as well as a warning label. Some of the warnings are that taking large doses of Acetaminophen can be sever on the liver. The warnings also mention about not consuming three or more alcoholic beverages with this medication. If a sever sore throat last longer than two days the user is advised to call their doctor. The label

As the difficulty of analgesic therapies rises, establishment of the priorities of care must be forced in order to avert or diminish adverse events from occurring and to ensure that high quality and safe care is followed through. Opioid analgesia, in particular, remains to be the main primary pharmacologic intervention for managing pain in hospitalised patients. Although, while opioid use is generally safe for most patients, it may be associated with adverse effects, the most serious and severe opioid-related adverse event being respiratory depression (Davies et al.

Single drug tests are made to screen and detect only one kind of drug, like Cannabis. Multi drug tests are made

In conclusion, drug testing is useful in the workplace for workers to work better and be more productive at their jobs. The worker has a cleaner environment to work and helps keep away illegal items. There are many benefits for drug testing and is necessary for the

The most common method is a urine sample. Although a quick way of testing, there are many negatives that have accompanied this type of test. The first problem started with the issue stated above. If the tests are simply preliminary or are expected, employees can discontinue drug use for the days leading up to the test and pass. The other problem is with adulterated tests. “Unless sample collection is directly observed, such tests are easily defeated” (Colakis 2007). For this reason, lab technicians and other personnel involved are not entirely sure of the circumstances during the testing and cannot confirm the urine specimen is from the correct
