With marijuana becoming legal in more and more states across the country, many people are using marijuana products or other similar products derived from the cannabis plant (though some come from hemp instead). 

Marijuana and these other similar products contain THC at varying levels. Even though it’s legal in many states, there are still jobs that test for THC levels and will reject applicants if the tests come back positive. 

Other people need to keep low levels of THC when they’re in rehabilitation programs for drugs that are unrelated to marijuana, CBD, or CBG. Some of these products replace opioids and alcohol for addicts, and they may help the consumer. They’re still not “allowed”. 

If you’re worried about how THC levels register in different drug tests, you’re in the right place. Keep reading to learn more about what’s going to be traceable and what you should be safe with. 

What Are the Different Kinds of Drug Tests?

There are several different kinds of drug tests, and they all pick up different amounts of THC (or whatever else they’re looking for). Some are more common than others, and some are reserved for more serious situations (like those involving the law).

Knowing the kind of test that you’re going to take is helpful if you’re trying to determine the amount of THC that you can have in your system without setting off any alarms. We’ll go over this first before helping you determine how much you might have in your system, depending on the type of product that you’ve consumed.

These are the more common types of drug tests that you might encounter in the workplace and elsewhere.

Urine Test

A urine test is the most common form of drug test. It’s easy to administer, and the results are quick. It is also the easiest test to fool if the person who is administering the test and the person taking it are in different rooms.

Urine tests have a range of capabilities regarding their THC detection, but they average out at 50 nanograms (ng) per milliliter. A nanogram is one billionth of a gram, for perspective.

While these tests are easy to fool, they also have a long period in which they can detect THC. If you’re using marijuana, for example, you may need to wait weeks before your levels will be undetectable. Recreational marijuana has high levels of THC.

Other products with trace amounts of THC may not be detectable even the day of the test, though it will depend on its sensitivity. If you’re using full-spectrum CBD, for example, which can contain up to .3% of THC, you may want to give yourself some time. 

Saliva Swab

An oral swab is an unreliable testing method, but it’s another popular one because it’s so simple. Employers who aren’t that concerned with THC usage may be more inclined to use this test.

In people who only occasionally use products containing high levels of THC, the test was only positive for up to three days after use. Those who consume these high-THC products every day had a wider window of about a month.

The levels of THC in weed are high, yet the test is still ineffective. This kind of test won’t detect low THC products such as CBD and CBG.

Blood Test

While many would think that blood tests would be the most sensitive, they can only detect THC for a few hours before becoming ineffective. 

That means that products with high THC levels might be detected for several hours, but products with low THC levels won’t be detectable at all. The nanograms per milliliter would be too low to register on the test.

Hair Test

The hair test is the most sensitive test on the market, but that works against it. It’s also known to be the most unreliable. Its hypersensitive detection abilities make it prone to inaccuracies. 

It isn’t uncommon to have false positives from hair tests even from being around a casual cannabis user, especially if they touch your hair (such as a friend, partner, or even hairdresser). 

This type of test can be reliable for up to 90 days after THC consumption, and it’s the only one that could be triggered by products with low levels of THC, but the unreliability of the test means that you aren’t likely to encounter it. 

Will My Product of Choice Trigger a Drug Test?

If you’re consuming marijuana regularly (whether through smoking, edibles, or any other method), you will test positive on a urine test if you don’t wait the appropriate amount of time before testing. Marijuana has the highest THC level.

There are methods through which you can get THC out of your system faster, but they’re unreliable. Tricking the test is possible, but it requires sneaky methods like using fake urine or getting someone else’s urine to take your place. 

Unless you smoke on the day of the test, you are unlikely to test positive on a blood test, and if you’re not a chronic smoker, you’ll be unlikely to test positive on a saliva test. The nanograms per milliliter are too low. 

When it comes to other products in the cannabis or hemp family, CBD and CBG can contain trace amounts of THC. While CBD may trigger a hypersensitive urine test, this is uncommon. Pure CBD will not.

CBG has even lower levels of THC, meaning that it will be virtually undetectable through standard testing. While it may trigger a positive result in a hair test, this can be attributed to the false positives that this test is known for. Even if you had your eye on a CBG isolate kilo, there’s nothing to be concerned about. 

In short, marijuana is the only thing you should be concerned about when it comes to drug testing. 

Are Your THC Levels Low Enough for a Drug Test?

Tests can detect THC in the body for a while, but products with low levels of THC won’t set off the average drug test. If you’re worried about your low-THC cannabis and hemp products triggering a test, you may want to skip a week or so to ease your anxieties, but these tests aren’t often strong or accurate enough to detect such minute THC levels.
