After you use a wax pen, THC may be detectable in your urine for about 30 days, depending on how frequently you use THC, the testing method, and other factors.
Drug tests look for THC and its byproducts — called metabolites — that remain in your system long after you use cannabis.
The time THC stays in your urine can vary, depending on multiple factors. The more you use cannabis, the longer it takes for traces of THC to leave your system.
For urine tests, the period of detection — that is, the length of time that THC is detectable after use — depends on how frequently you use THC.
Cannabis metabolites are fat-soluble, which means they bind to fat molecules in your body. If you use cannabis often, THC may build up in your fat cells, which causes a higher baseline concentration of THC metabolites.
This means people who often use THC can test positive for THC for longer than people who don’t use it often.
A 2017 research review suggested that THC may be detectable in urine for the following amounts of time after the last use:
- first-time or infrequent use: 3 days
- four uses per week: 5 to 7 days
- daily use: 10 to 15 days
- multiple uses per day: more than 30 days
Some urine tests are less sensitive than others, though. Certain tests may stop detecting THC as soon as one day after use.
But if there’s a chance you’ll receive testing for cannabis, it’s best to prepare for the possibility that the urine test will be accurate for longer.
Police may perform saliva testing for roadside testing to find whether someone has recently used cannabis. Saliva tests have a fairly short window of detection. In some cases, they can detect
However, a small 2013 study noted that blood tests detected THC
After you use cannabis, the chemicals enter your bloodstream and reach your hair follicles via the tiny capillaries in your scalp. The sweat and sebum surrounding the hair shaft can also contain THC metabolites.
Hair grows about 0.5 inches in a month. When testing for drugs, someone may take a 1.5-inch hair segment to test for drug use during the past 3 months.
There’s little to no evidence that THC ingested via wax pen will metabolize differently from THC ingested via smoking cannabis.
When you smoke, vape, or ingest cannabis, the
These metabolites remain in your body long after you use THC. Even after the effects of cannabis wear off, the metabolites are detectable in your urine and saliva. Drug tests look for THC metabolites, not just THC itself.
Eventually, your body eliminates THC metabolites via your urine and stool.
Many factors affect how long THC stays in your system, including:
- How often you use cannabis: If you use cannabis often and in high doses, it’ll take
longerto eliminate THC from your body.
- How you ingest cannabis: For example, if you consume cannabis edibles, THC may
stay in your systemlonger than if you smoke or vape.
- Kidney and liver function: Since your liver and kidneys play a huge role in helping your body process drugs and eliminate them from your body, THC may stay in your system for longer if you have kidney or liver conditions.
No, not really. There’s little evidence to suggest that there’s anything you can do to metabolize THC faster, nor is there anything you can do to eliminate THC metabolites faster.
If you’re concerned that you may receive testing for drugs, there’s little you can do other than abstain from further THC use. Drinking a decent amount of water can help keep your kidneys healthy, but there’s no evidence that it’ll help you pass a drug test.
Some cannabis detox remedies and kits involve drinking a lot of water to flush the metabolites out of your body and then using creatinine or vitamin B12 to mask the dilution. There’s little research on whether these kits are safe or effective.
Also, avoid drinking large quantities of water in a short time. This can cause overhydration, which can be harmful.
Is a wax pen the same as a dab pen?
Yes. Wax pens and dab pens are portable devices used to vape cannabis concentrates. Wax is one type of cannabis concentrate. People can also use many devices to vape budder, crumble, shatter, and other concentrates.
Is a wax pen the same as a weed cart?
Not exactly, but they’re similar. A weed cart — short for cartridge — contains THC oil or concentrate.
People don’t usually use wax pens with a weed cart. Weed carts need to attach to a battery or pen.
Wax pens usually come with wax inside the pen. But certain devices may allow you to use cartridges and a concentrate chamber.
Is a wax pen the same as live resin?
You can use a wax pen to vape live resin. When it comes to cannabis concentrates, live resin usually has a more potent effect than wax.
Will delta-8 wax show up on a drug test?
Yes, delta-8 THC will probably still test positive for THC use.
So, although delta-8 may technically not be illegal where you are, you may still experience legal difficulties if you get a urine drug test after using it.
Will delta-10 wax show up on a drug test?
There’s little research on this. Some internet users have warned that delta-10 products have caused them to test positive for cannabis use, but this is only anecdotal — and it’s possible that those delta-10 products also contained delta-8 or delta-9 THC.
Delta-10 is so chemically similar to delta-8 and delta-9 THC that delta-10 wax may show up on a drug test. If you use delta-10, your urine may test positive for THC.
It may be best to avoid delta-10 if you know you’ll receive testing for cannabis.
Will CBD wax show up on a drug test?
Although there are no studies about the detection test for CBD wax specifically, a 2021 case report looked at a person who smoked one 250-milligram (mg) CBD-rich cannabis joint daily for 26 days.
The joint was 6.0% CBD (15 mg) and 0.2% delta-9 THC (0.5 mg). The researchers detected THC metabolites in the person’s urine after 8 days of smoking.
So, if you may get testing for THC, it’s best to stick to CBD products that are THC-free.
After using a THC wax pen, you could test positive for cannabis for about 30 days after use.
However, the detection window could be much shorter if you use THC infrequently. Infrequent or first-time users may test negative for cannabis use as little as 3 days after using a THC wax pen.
Your biology and how you use THC may affect how long it stays in your system. The same applies to delta-8 THC and delta-10 THC products, which can cause you to test positive for drug use.
