Drug testing has been enforced for at least 2 decades in many companies to determine whether business's employees use drugs. The most usually abused drugs detected by drug tests are marijuana,
hashish, cocaine, herion, ecstasy and others.
There are different types of drug tests carried out at present. Most commonly, urine, saliva, hair samples are taken and checked in a testing lab. Drug examination can be also conducted on-site, which spares a lot of business's funds and is a lot convenient for employees.
Thus, one of the most commonly used on-site drug test is the oral swab. It is inexpensive. The business spends almost $1.00 per test. Besides, it not that embarrassing as collecting urine specimens. More than that, saliva tests are quick. Hence, the results get ready in a few minutes. In addition, these drug tests are harder to adulterate than urine drug tests, since specimens are collected under direct supervision. Though being donor friendly, non-invasive and very easy to run, oral fluid drug tests are appropriate for determining very recent drug abuse. At least 6 types of drugs can be determined in this way.
One more way of drug checking is examination of urine samples. Up to ten types of drugs can be detected by means of urine drug tests. There are 3 kinds of a urine test: dip form, cassette form and cup form. The employee's urine is gathered in a specially made secure cup and closed off with a tamper-proof tape. The cup is then directed by express delivery service to a testing laboratory where it will be tested for drugs.
Hair testing is thought to be reliable and can detect drug use as far back as 90 days. Since hair grows out, any drugs taken are encased in the hair shaft. Longer hair can provide an individual's drug history spanning a longer period of time than shorter hair. Human hair grows out, on average, 0,5 inches a month. As a rule, testing labs need about 0,5 - 1,5 inches for testing. It provides information on about 30 - 90 days of drug abuse.
Spray drug tests are also easy to run. They are very accurate and difficult to adulterate as well. But the number of drugs detected by a spray drug test is very limited.
Though a lot of employees and privacy advocates find drug screening a brutal intrusion of privacy and breech of one's rights and freedoms, drug tests are still carried out by employers, since drug abuse is often the reason for absenteeism, health problems and on-the-job accidents.
