What is THC, and Why is It So Popular?

THC, also recognized as Tetrahydrocannabinol in full, is one of the several cannabinoids in the cannabis plant. It’s the main psychoactive element and functions similarly to the natural body-made cannabinoid.

Cannabinoid receptors are detectable in certain aspects of the brain and are associated with pleasure, memory, thinking, and more. THC affects these brain areas by attaching to and activating these receptors.

One reason for THC popularity is that the FDA has already approved the use of a synthetic THC formulation known as Dronabinol for tackling certain health challenges. A few health problems are a lack of appetite resulting from HIV/AIDS anorexia and chemotherapy-induced nausea and puking.

Also, THC substances are used for dampening pain, another reason for their popularity. Moreover, the “high” feeling it gives is also a reason for its wide adoption among teens and adults globally.

The Usage of THC Substances in the U.S.

The use of THC-contained substances is significantly rising in the United States for some reasons like its health benefits. Moreover, the larger public proposes the legalization of this substance for recreational and medical purposes.

As per the data from Pew Research Center, 88% of U.S. adults support this motion. Meanwhile, only 10% disagree with the idea.

At the federal level, convicts of marijuana possession have received a pardon from President Joe Biden. This order was released before the midterm election on November 8, 2022.

But in the period leading up to the election, two states had already legalized the recreational use of marijuana. They now add up to the 19 states and Columbia District, which already permitted substance use.

When And Why Do Employers Drug Test?

The need to conduct drug tests for employees could be based on state laws. A common misconception about drug testing is that employers require it due to a lack of confidence and trust in their employees.

Drug-testing employees have been the order of many businesses and companies for several years. It’s a safe practice that protects the company and its staff.

When Do Employers Drug Test?

  • In most cases, drug testing occurs during a recruitment process
  • Drug testing may also be needed regarding state law
  • Employers may need to drug test employees depending on the company’s industry. Such industries include safety, transit, transportation, aviation, defense, hospitals, and schools
  • County, state, and federal applicants may also need to undergo the drug test procedure by their employers

Why Do Employers Drug Test?

  • To confirm whether or not the new intakes have issues with drug abuse
  • Some employers may have rules that prohibit the use of drugs. This test ensures that no employee who does drugs gets into the workforce
  • Employers perform such a procedure to ensure the company’s and employees’ safety. This is crucial, as it determines the productivity of the business
  • Drug testing may also be performed to confirm that employees comply with the organization’s ethics

There are two forms of drug testing, random and pre-employment drug testing. Here’s a detailed explanation of these drug testing types.

Random Drug Testing

Random drug testing occurs without a prenotification to the already existing employees. This form of drug testing is necessary to confirm the compliance of current employees with the company’s drug-free instructions.

Pre-Employment Drug Testing

Pre-employment drug testing is performed on prospective employees. The purpose here is to confirm their drug status. This process allows employers to screen new intakes to ensure they’re free of drug abuse upon joining the team.

How Long Does Weed Stay In Your System?

The internet is flooded with common questions like how long does weed stay in your system, particularly from job seekers? You can also find questions like how long does delta 8 stays in your system.

The effects of weed might wear off in a few hours after inhalation or ingestion. However, the presence of THC residues can still be detected weeks later. While this is true for chronic or heavy users, the same detection time doesn’t apply to moderate and rare users.

For moderate users (3 to 4 times a week), the presence of THC can be traced 5 to 7 days after ingestion. As for rare or one-time users, physicians can detect the presence of weed three days after consumption.

UsersUsageDetection Periods
Chronic Heavy UsersSeveral times dailyAbout 30 days after the last consumption
Chronic UsersDaily consumption10 to 15 days following the last use
Moderate Users3 to 4 times a weekDetectable within 5 to 7 days
Light UsageOne-time usageCan be traced within three days

The Metabolism of THC

The most recognized way of taking marijuana is through inhalation. Another common form of consumption is ingestion. When a consumer inhales this substance, the lungs quickly absorb the THC compound. Minutes later, marijuana gets into the bloodstream.

In the case of ingestion, it takes up to 1 hour, 30 minutes to 3 hours before THC enters the bloodstream. Afterward, it fuses with the blood proteins and travels to several body areas. These include the heart, fat, brain, and ultimately, the body tissues absorb it.

During this process, the compound may damage certain organs while adversely affecting the brain. The initial stage of the metabolism process is very fast. But it slows down during the transmission of THC into the liver and bloodstream.

Furthermore, the liver can form marijuana metabolites from the THC compound. The consumer may excrete these water-soluble metabolites through urine before the body tissues absorb them.

What Factors Affect How Long Does Weed Stay in Your System?

Many factors, including frequency, method of intake, body mass, gender, genetics, etc., affect the time weed stays in your system. So, consider the factors below if you’re wondering how to get weed out of your system in 2022.

Usage Frequency (Dosage)

The first determinant of the question, “how long does weed stay in your body” is the number of consumption times. This is relative to the dosage since it shows the amount of THC compound your body receives per time.

As a result, THC residues would clear off from the systems of infrequent users faster than chronic users.

Intake Potency and Method

Weed with more potency contains a higher concentration of THC compound. So it could remain in your system longer than expected. Additionally, ingested weed lasts longer in the body than inhaled ones.

Body Mass Index – BMI

Consumers with more body mass are likely to retain THC in their systems longer than those with lesser fatty tissues. The reason is that fatty tissues store THC, and these tissues are not abundant in individuals with lesser BMIs.


Genetics is also a significant factor when answering the common question, how long does weed stay in your system? Not everyone possesses the same metabolism capacity. So, individuals with high metabolism levels have shorter detection times than the others on the flip side.


Generally, females possess more fatty tissues than males. This fact increases their chances of having longer detection times since cannabis hardly metabolizes in fatty bodies.

After considering these factors, you want to look at purchasing an effective detox to flush out THC remains from your system. Some folks would suggest the use of homemade remedies to tackle such issues. While this option may seem okay, there’s, however, a limit to its potency.

This is where top-notch detox supplements like Toxin Rid come in. These products eliminate traces of THC compound present in the body regardless of the detection time.

How Long Does Weed Stay in Urine?

Often, the question, “how long does weed stay in urine” arises in anticipation of a drug test upon employment. Well, in a heavy consumption situation, weed may last up to a month in urine.

Other times, it could remain detectable for around two weeks or a few days, depending on the intake frequency. Generally, THC detection times in urine depend on dosage and frequency of usage.

For many organizations, the most common strategy to detect the presence of weed in the body is through a urine test. This is mainly due to the simplicity of collecting the sample. Also, a urine test is quite effective for detecting recent and short-term use of such drugs.

Usually, THC stays traceable in urine within 2 to 3 days, though certain factors may alter this period. A few of them are:

  •       The specificity of the test
  •       Test sensitivity
  •       Dosage
  •       User’s metabolism rate
  •       Frequency of consumption

Home-based urine testing is not very effective, particularly for long-term drug use. Nevertheless, several people still implement this strategy, though it can’t take the place of thorough testing in the laboratory.

Furthermore, certain parameters can affect the results of home-based urine testing. A few of them are as follows:

  •       The method applied to run the test.
  •       Taking some other form of drugs or prescription a few leading up to the test.
  •       The method of storing the urine sample or test.
  •       Meals and drinks ingested before the test

Why Toxin Rid is the Best Product?

Detox products are abundant in several online and on-site shops, but Toxin Rid remains the most recommended.

It’s made from natural ingredients

All ingredients in the Toxin Rid pills are natural, which only contributes positively to your health. Primarily, Toxin Rid pills contain vitamins, herbs, and minerals that are harmless to the body’s system.

Other ingredients to point out are:

  • Calcium
  • Chloride
  • Boron
  • Potassium
  • Kelp
  • Iron
  • Alfalfa extract
  • Sodium
  • Magnesium

Vitamins – These are organic compounds contained in animals and plants. They’re vital for the proper functioning of the body cells and are ideal for boosting the immune system.

Herbs – are other natural ingredients like garlic that contribute to a healthier heart and help to prevent diabetes and cancer. They also come in handy for dampening the chances of blood clots and provide anti-tumor and anti-inflammatory properties.

Minerals – These ingredients boost the overall health of the body. Minerals contribute to healthier bones, heart, brain, and muscles while promoting their proper functioning. They’re also helpful in generating hormones and enzymes.

Fast working solution

It only takes an hour for the working process to start. But it doesn’t imply that the results are as fast. Unlike other options, it simply means the detoxification process begins within an hour.

Simplifies the detoxification process

Usually, during the detoxification process, patients lose lots of electrolytes and fluid. Often, this occurrence leads to lightheadedness, headache, weakness, etc. But this doesn’t apply to Toxin Rid due to the presence of vitamins and minerals in the pills. These nutrients help to replenish what the system loses during the drug-ridding process.

Multiple options available

Toxin Rid provides users with different medication duration kits, like the 5-day and 10-day options. The right choice for you depends on your drug test time and history.

Backup Plan: Synthetic Urine

Fake or synthetic urine is relative to artificial urine, an alternative to a positively tested urine sample. It has the same characteristics as real human urine and possesses the same constituents. A few elements to note here are nitrates, ammonia, and creatinine.

This product also exudes a similar odor as human urine, and manufacturers do enough to keep it untraceable from drug testing. Individuals needing synthetic urine can get it for as low as 15 dollars.

Drug Testing with Synthetic Urine

Synthetic urine could fail in a drug test, though the chances are slim. Illicit drug users may opt for synthetic urine to escape the possibility of detection within 24 to 48 hours preceding a drug test. Another option, though less unique, is diluting the urine.

Certain weed consumers go as far as using lemonade, dog urine, or other household options to alter positive test results. While this seems quite illegal, the majority of them succeed at it.

Will Synthetic Urine Work?

Synthetic urine may work depending on the detecting method of the company or organization. Not every firm possesses the right equipment or mechanism for detecting fake urine. So, testing for pH levels and validity may not be possible in such settings.

A pH level drug test determines whether or not the urine is diluted. On the other hand, validity confirms the presence of creatinine and temperature levels in the urine sample.

Furthermore, a company implementing the right urine-detection method will fish out fake urine, given the wide range of areas the drug test covers. Drug users should be aware of this possibility when opting for such a backup plan.

Meanwhile, synthetic urine products with ample constituents help you evade sudden urine drug tests. A good example of such a product is TestClear.

TestClear Powdered Human Urine Review

Test Clear is a dehydrated form of real human urine, primarily created to escape anticipated drug testing. This powdered form of urine acts similarly to natural human urine when mixed with water.

Why is TestClear the Best?

About 11 to 13 chemicals of natural urine are present in Test Clear. This formula makes the product right to scale through any urinalysis. This gives Test Clear an edge over other similar products on the market.

Shipping Method

The shipping carriers of the TestClear product include FEDEX, USPS, and UPS. Customers are open to shipping options from these carriers like 1-day, 2-day, 3-day, and Ground Shipping.

However, deliveries may take additional days for products shipped to Hawaii and Alaska.


The TestClear powdered urine kit sells at $49.95, and it offers a 100% money-back guarantee to both new and existing customers.

How Long Does Marijuana Stay in Your Hair?

Some of the regular questions from prospective employees are can a hair follicle test detect one-time use? How long does marijuana stay in your hair? Well, as per one-time use detection, it’s possible to trace marijuana in hair follicles after a single dosage of weed. Also, the detection time of marijuana in your hair typically depends on usage frequency.

Here’s the thing, metabolites of marijuana or cannabis can enter the hair bulb through the bloodstream by diffusion from sweat or sebum around the hair shaft.

It can also get in by external contamination (contaminated fingers and side-stream smoke). The American Addiction Centre indicates that THC and other marijuana metabolites can last up to three months in the hair.

Hair follicle testing is another method for assessing marijuana in the system. According to research, it has the longest detection time. The hair follicle tests can detect drug use for up to 90 days.

Hair grows approximately 0.5 inches per month. Therefore, a 1.5-inch segment of hair taken from the scalp can detect a window of weed intake for three months after the last use.

THC can get into your hair at the slightest physical contact with a marijuana smoker. It could find its way into a non-smoker’s hair strands through contact with contaminated surfaces and provide a false positive result.

That is why hair testing is the least reliable method for cannabis testing.

Old Style Aloe Toxin Rid Review

Hair follicle drug tests can be very disturbing as many people fail them despite observing adequate precautions. Drug metabolites like THC can remain in your hair for over three months after the last use.

That is why you must use the best product to cleanse your hair from toxins before going in for a hair follicle drug test.

How It Works

The Old Style Aloe Toxin Rid Shampoo uses a purifier that can penetrate the innermost layer (medulla) of the hair shaft. It washes hair from within, not just the surface or cortex. Removing drugs from your hair can be tasking but not impossible with Old Style Aloe Toxin Rid Shampoo. It is probably the only product that works out of all the tricks available.

One of the main ingredients in the shampoo is propylene glycol, which has a special detoxifying effect on the hair. It also contains EDTA, which acts antioxidant.

However, it doesn’t remove everything in one wash. As you know, the hair medulla contains an amorphous and oily substance that allows drug metabolites to stick and makes it difficult to wash. That is why passing a hair drug test is difficult for most people.

You must wash with Old Style Aloe Shampoo about 15 times, each lasting for 15 minutes, before your drug test. You can also apply the Old Style Aloe Toxin Rid using the Macujo Method a day before your test.

Additional Details

The price ranges from $199.95 to $235. Shipping can be done within and outside the United States through UPS, FedEx, and USPS. You can contact the manufacturer directly for a rebate if the product does not satisfy the performance of the purchase.

How Long Does THC Stay in Saliva?

Research suggests that significant absorption of THC occurs in the mouth and increases in concentration for several hours after use.

How long does THC stay in saliva?THC stays in the oral fluid longer than in the blood after acute use. A saliva test can detect it in the saliva even 72 hours after use for heavy smokers. But  THC metabolites can be detected in the saliva of a regular or chronic weed smoker for up to 30 hours. The detection time for irregular users is between 24 hours to 4 days.

Salivary tests have a short detection window and may also detect same-day cannabis use. It works for roadside testing and in workplaces to assess the use of illicit drugs. It uses a swab to collect oral fluid between the lower cheek and gum.

How Long Does Weed Stay in Your Bloodstream?

How long does weed stay in your bloodstream is another popular question among potential employees. You might also want to ask, can you fail a drug test from secondhand smoke? The fact remains that once marijuana is ingested or inhaled, it resides in your system for a period.

For light users, the detection period could be as low as 2 to 3 days after the last intake or inhalation.

Frequently Asked Questions – FAQ

Can I Run Drug Testing at Home?

Anyone can perform a drug test simply and conveniently from the comfort of their homes. However, you must follow the right method for the test.

How Long Does a One-Time Smoke Session Last in Your System?

If you’re not a regular weed user, a single smoke session should last up to 3 days. On the flip side, it could last for over a week or two if there are residues of THC in your system before your last intake.

Furthermore, you can expect the drug to be detectable in your system after 30 days if you’re a chronically heavy user.

Are Homemade Remedies Useful?

Home-made remedies are not so efficient in detoxing your system of THC residues. While they may help light or one-time users, chances are that they’ll fail for moderate, chronic, and heavy users.

Certain detox products promise to eliminate every atom of THC in your system. One of the most common and recommended ones is Toxin Rid. As the name suggests, it rids your system of both short and long-term weed residues, leaving your system 100% clean.
