With that said, THC remains detectable in the blood, urine, and saliva for different periods…
Top 8 Legal THC Gummies to Buy in 2025
THC is the same whether it comes from hemp or marijuana. No matter the source, THC will show up on drug tests. However, potent hemp-derived THC gummies are federally legal in the US, meaning they’re accessible in most states without repercussions.
If you want to use THC legally, high-potency legal THC gummies may be the best option, including hemp-derived delta-8 products. Just make sure to buy from reliable online dispensaries and vendors that value transparency and safety.
Here are the top eight best legal THC gummies in the US:

How Long Does THC Stay in Your System?
Whether you’re smoking the best hemp THCA flowers, puffing on top-quality delta-8 vapes, hitting a bong, or eating the best THC gummies, THC hangs around in your body long after finishing your session.
For joints, this tends to be around 3 days for non-habitual users.
Regular cannabis consumers tend to have higher levels of THC in their bodies, so it can take up to 30 days for THC to leave their system.
Edibles like THC gummies can remain in the body for a couple of weeks, though the same rules apply in terms of frequency, dosage, and individual metabolism.
Higher doses combined with frequent usage extend the time THC can be found in the body and vice versa.
1. How Long Does THC Stay Detectable in the Saliva?
THC remains detectable in the saliva glands for 24 to 72 hours after the last use.
Saliva swab drug tests are common on the roadside and in employment. If you expect to undergo saliva drug screening, make sure you cease using THC in any form at least three days before the test is due.
Hemp THCA vapes and pre-rolls, as well as potent THCA flowers offer a nice and legal way to get a little high. But remember, THCA converts to THC when heated. So, yes, try to avoid THCA before a drug test, too.
If you’re also consuming hybrid THC gummies for relaxation or indica THC gummies to help you sleep, you might want to switch to CBD for a while. CBD offers an equally relaxing and soothing effect.
Plus, CBD doesn’t show up on drug tests, which are sensitive to THC and its metabolites, not CBD. Just make sure that the product doesn’t contain THC, though, such as broad-spectrum CBD or CBD isolate.
2. How Long Does THC Stay in Urine?
A urine drug test can obtain a positive THC result if the cannabis was ingested within three to seven days. This strongly depends on the dose and frequency, as heavy users can flag a positive even 30 days after the last use [1].
THC remains in urine for the following timeframes:
Infrequent users: 3–7 days
Regular users: 10–30 days or longer
THC remains longer in urine and hair than in the blood, and if you’re a regular cannabis consumer, this means urine tests are very likely to come back positive. If you know that you are going to be subject to a drug test, it’s best to avoid THC-containing products for at least three weeks to a month to be on the safe side.
3. How Long Does THC Stay in Your Hair?
Although less common, it’s still possible to test for THC through hair samples. As cannabinoids move into the hair follicle, tests can return a positive several months after the last use [2].
THC remains detectable in the hair follicle for up to 90 days. Hair follicle tests are most common in the military and government job roles.
4. How Long Does THC Stay in Your Blood?
THC is usually detectable in the blood for a couple of days after use, but in heavy users consuming regular doses, it can hang around for up to a week. Drug tests on the blood measure THC metabolites, which linger in the body even after the effects have worn off.
Habitual consumers of law-compliant delta-9 THC or even hemp THC tinctures can expect the cannabinoid to stay in their bodies for a minimum of a week, though higher doses and more frequent use can extend this window.
How Does Your Body Process THC Gummies?
After consuming THC gummies, cannabinoids are absorbed through the digestive system before metabolization occurs in the liver. During this process, THC is converted into a more potent form — 11-hydroxy-THC — which circulates the body through the bloodstream.
This THC metabolite crosses the blood-brain barrier, delivering an intense high. Experiences are typically stronger when delta-9 THC is ingested as edibles than when smoking or vaping with longer-lasting effects [3].
How Long Does It Take for THC Gummies to Kick In?
The light-headed, floaty feeling after hitting a joint takes place within moments, but the effects of THC gummies take considerably longer to kick in.
The effects of THC gummies can take anywhere from 30 minutes to two hours to kick in [3]. Taking another dose is tempting if you can’t already feel the effects, but this can lead to dose stacking and extra powerful effects when they do eventually hit.
The onset time of THC gummies depends on individual metabolism and whether they have been consumed on an empty stomach. Although it can take up to two hours for the effects to begin, they can last for several hours — sometimes as long as 10 hours.
As for inhalable products like legal weed carts or hemp THC cartridges, the effects kick in in less than 15 minutes.
Do THC Edibles Show Up On Drug Tests?
Cannabis edibles and hemp-derived THC gummies, including hemp delta-8 gummies, contain THC. It’s this THC that flags positive results, and this can happen regardless of eating, smoking, or vaping cannabis products.
Drug tests analyzing urine, blood, and hair can all come back positive if you’ve used THC gummies recently. The risk of producing a positive result is increased in heavy users dosing THC frequently.
You should also be mindful of full-spectrum CBD gummies and high-CBD stress gummies. Even though, in some cases, it’s a trace amount, they will still contain THC.
So, even if you are taking CBD gummies for therapeutic rather than recreational use, you could still be caught out.
How about Amanita muscaria gummies? Will you test positive after consuming a bite or two?
Well, it depends. If it contains shrooms alone, it might not trigger a positive test. Common drug tests are usually not sensitive to mushrooms and their active ingredients.
However, if the shroom gummies contain THC, then it could result in a positive drug test.
FAQs: THC Gummies in Your System
Don’t get in a muddle over how long THC can stay in your system.
Let us guide you through the answers you need with our FAQs.
1. Does Metabolism Affect How Long THC Stays in Your System?
Everyone’s metabolism is different, and this can impact how long THC remains in the body. Users with faster metabolisms can clear THC quicker than those with slower metabolisms. This may make the detection window shorter for faster metabolisms, though this doesn’t have much of an impact on heavier users [4].
2. Can Drinking Water Help Flush THC Out of Your System?
Drinking water may help dilute THC metabolites in urine, but it won’t have much of an effect on the speed of elimination. Keeping hydrated with enough water promotes urine production, which can help flush out THC, but it may still be found in the blood and hair.
3. Are THC Gummies Detectable Longer Than Smoking Weed?
THC gummies and edibles, in general, have a longer detection window compared to smoking weed. This is due to the way THC in edibles is metabolized and can be affected by dosage and frequency of use. Regular edible consumers typically have higher levels of detectable THC in their systems.
4. Can Exercise Help Reduce THC Levels in the Body?
Exercising is beneficial for overall health and can burn fatty tissue where THC is stored. THC is fat-soluble and thus gets stored in the body’s fatty tissues. Exercises targeting fat loss may help reduce THC levels slightly, but this can take substantial time.
5. How Accurate Are At-Home THC Drug Tests?
The accuracy of at-home THC drug tests is generally good. However, they aren’t as reliable as lab tests completed in a fully controlled environment with specialized equipment. For the most accurate at-home drug test, follow the instructions carefully and complete each step as precisely as possible.
6. Does Body Fat Affect How Long THC Stays In Your System?
The body tends to store THC in fatty tissue or cells, meaning individuals with higher levels of body fat may retain THC for longer. Users with a lower body fat percentage can get rid of THC from the body more quickly; this is also the case for users with fast metabolisms.
7. Can Secondhand Smoke Cause THC to Appear in Drug Tests?
Secondhand smoke doesn’t usually flag a positive result from a drug test, but it may be possible in extreme cases. This may happen if an individual is present in an unventilated environment where cannabis is being smoked. It’s possible to experience a contact high from inhaling secondhand cannabis smoke.
8. How Long Before a Drug Test Should You Stop Using THC Gummies?
THC in edibles such as gummies can remain in the body for a couple of weeks for occasional users but up to 30 days for regular users. Heavier users should stop using THC a month before a drug test, but infrequent users should be clear in one to two weeks.
9. Are Blood Tests More Accurate Than Urine Tests?
Blood tests can produce more accurate results in terms of recent use, but urine tests can expose cannabis use over a longer period. Urine tests can also detect a wider range of drugs, but it’s hair follicle drug tests that can flag cannabis use for the longest period since consumption.
10. Can THC Gummies Cause False Positives On Drug Tests?
THC gummies don’t cause false positive drug test results. Cannabis edibles only produce true positives if THC metabolites are present in the body. Most forms of cannabis consumption will lead to positive results in blood, hair, and urine tests regardless of the way THC was taken.
