There are SIX standard methods for testing for drugs and alcohol

Despite the fact that drug and alcohol abuse has far-reaching consequences for society, it can be especially harmful in the workplace. Employees can decrease productivity, causing a company's revenue to fall. Employees that have Addiction to drugs or alcohol is 2-5 times more common to be late or sick become abusive, or suffer injury, according to the National Safety Council.

Here are a few more concerning statistics:

Opioid misuse is responsible for 50% of occupational deaths and 40% of workplace fraud.

70% of the 14.8 million people who misuse drugs in the United States work;

74 percent of illegal drug users work, and they are responsible for 40 percent of all factory deaths worldwide.

Many companies have drug-testing systems in place to detect the use of recreational marijuana and illegal substances, alcohol, or prescription drugs. The tests differ according to national, local, or federal rules, as well as the substances being studied.



Drugs and alcohol, how long do they last in the system?

The duration of drug and alcohol effects on the body vary significantly. Cocaine high, for example, lasts 15-30 minutes. However, clear signs will last for longer in the body. LSD (Lysergic acid diethylamide) highs last 6-12 hours. Alcohol has a wide range of effects. For example, it can take up to 7 hours for an adult male to metabolize alcohol to the point that His blood-alcohol concentration, or BAC, returns to negative. Alcohol can be found in the saliva and blood for duration of up to 24 hours after ingestion and in urine for up to 80 hours.

Approaches to testing can differ depending on how long a drug remains in the body until the effects have worn off. Some medications leave traces after just a few days, while others remain for months.

Some of the reasons that influence how long a drug stays in the body/system are as follows:

Ø Amount consumed

Ø Frequency of use

Ø Scales of hydration

Ø Medical status

Ø Metabolic rate

Ø Physical exercise

Ø Medication form

6 Different Types of Drug Tests

Tests also differ based on the material or drug being screened, as well as the kinds of samples used for lab examination. Below are the most popular forms of drug tests:

1. Blood Analysis

Although blood testing is more invasive than breath and urine samples, it is the most accurate in measuring individual levels of alcohol content. Certain blood tests will determine the exact degree of alcohol 24 hours after drinking.

Since conventional blood draws include a needle poke in the shoulder, many laboratories and other facilities now have a less invasive blood sample collection system. Small blood samples are collected for processing using volumetric absorptive micro sampling (VAMS®) technology.

To facilitate quick VAMS blood processing, a portable Mitra® system has been developed. Via a finger prick from a smear of blood on the tip of the digit, Mitra instruments collect blood "tiny samples." This method is less invasive and faster than traditional blood sample processing methods such as venipuncture.

Blood test findings can be more thorough than urine test results which show more than just the existence of substances. Researchers found that PEth, a strong biomarker of alcohol, can be detected in very small blood samples, providing accurate evidence. These blood tests can detect drug metabolites as well as the quantity or level of drugs in the blood.

Mitra instruments have been shown to capture high-quality samples, and they are now used in several opioid and alcohol rehab centers to collect blood samples from clients face-to-face. This method of sample selection eliminates the possibility of patients tampering with or substituting samples, as happens with urinalysis.

2. Breath Analysis

Law enforcement officers also use the breath test technique to check for alcohol consumption of drivers. Police officers use a breathalyzer to determine the blood plasma alcohol level of exhaled breath and water vapor. It is a common approach since sample collection is non-invasive and easy for roadside research. According to recent studies, roadside alcohol monitoring may involve finger-prick In the future, blood collection or micro sampling will be needed.

3. Hair Analysis

The metabolites of drugs penetrate the blood vessels of the scalp. The drugs are filtered into the hair, which holds a permanent record of drug use. This means that a patient who used marijuana, cocaine, alcohol, or some other material a long time ago would test positive and the opioid metabolites are now present in their hair.

4. Test of Saliva

Another minimally invasive saliva checking is a drug testing instrument. Saliva, on the other hand, is mainly suitable for checking for recent drug use. For example, saliva tests for marijuana will only produce correct outcomes if the subject smoked or consumed recreational weed within the previous 4-10 hours.


A sweat test entails the application of a patch to the skin. While these tests can detect drug residues in a person's saliva, they also have a high rate of false positives. Sweat checks aren't widely used because dirt and other contaminants may make them unreliable.

 6. Urine Examination

The most common measurement is the urine test instrument for detecting illegal substances. The "pee-in-a-cup" sample collection method is non-invasive; no needles are used. Urine samples can contain high levels of parent drugs (drugs being screened for) and drug by-products.

Urine samples, on the other hand, are less successful than other approaches at identifying narcotics and alcohol because they have a brief retrospective duration. In other words, after a 48-hour cycle, a urine test is less likely to detect daily substance use. Another disadvantage to urine monitoring is the simplicity with which the samples can be tampered with.
