There are lots of forms of drug screening available. However, the urine test is the most widely used. This test can check for drugs in five typical types. These are cannabinoids, or marijuana and hash, cocaine, or crack benzoylecgonine, opiates, or heroin, codeine, morphine, or opium, amphetamines, or methamphetamines and pace, and phencyclidine, or PCP. Urine drug tests are the cheapest of drug tests. Individuals that are against drug screening say that the pee test is invasive and that it can be misused by assessing a worker’s urine for pregnancy or for the presence of prescription drugs that may indicate a medical issue.
An employer could detect private medical facts about a job candidate
For instance, if the potential employer wishes to be sure a woman is not pregnant because of the fear which the individual will soon be out of work for some time for childbirth, a drug test could show pregnancy. The employer could also detect other medical facts, like if the job candidate is taking drugs for cancer or depression – both ailments an employer is legally not permitted to inquire about at a pre-employment interview.
Some types of drug screening reveal recent medication use
A urine test is one of these because it can show usage over the last week. These evaluations are subject to manipulation from employees, job candidates, students, and many others who don’t wish to risk failing the test. For this reason, urine drug tests are done under strict provisions that try to take this possibility away. Other drug screening systems can be found that reveal drug usage over a more extended period, such as the hair test.
These are quite a bit more expensive than urine tests
However, they’re the very best test for determining when the drug use occurred, and if it is still happening. Some drugs, like cocaine, morphine, and codeine stick to the hair, and laboratory professionals can determine when the last usage of the medicines occurred, dependent on hair growth of the penis. Hair tests do not typically find drug use that has happened within the previous week. These are not the appropriate screenings for discovering if an employee snorted cocaine before arriving to work that day because they cannot be detected employing a hair test.
Another test that is getting more popular is that the saliva test
Although it costs a bit more than urine testing, it is less costly than blood tests. Saliva tests may determine whether drugs are used in a previous couple of days, so they’re useful when it is vital to understand if the person has recently used drugs. Saliva tests are unusually high at finding methamphetamine and opiates. Blood tests are one of the types of drug screening available that provide the most precise results of illegal drugs in an individual’s system. They are invasive and costly, so they are not routinely used by companies for random drug tests. Ultimately, a form of drug screening that is not used very often is that the sweat patch screening. This can be a contentious evaluation because it can cause a false positive result if a person has just been around secondhand smoke out of marijuana.
