A 2017 study published in Drug and Alcohol Review analyzed hair samples collected from 136 subjects and found detectable levels of THC in 77% of chronic consumers and 39% of light consumers. However, there’s mounting evidence that hair follicle drug testing cannot detect cannabis accurately. Saliva tests can detect THC for up to 24 hours after last consumption in infrequent cannabis users, and up to 30 hours in regular and chronic users. In general, you can expect to pass a saliva test about two days after dabbing, about one to two weeks after for a urine test, and two to four weeks for a hair test. These numbers can increase significantly though if you are a heavy marijuana user. Before ingesting these edibles I had not smoked any marijuana in a little over a month.
Saliva test
People who use weed regularly and then stop abruptly can experience some withdrawal symptoms. It would be much more helpful if everyone would provide last smoked info, body stats, and if they passed or not. Even though exercise burns fat, that process also releases more THC metabolites into your blood, which could be a bad choice for the testing day. So if you want to flush marijuana out your system, start drinking a lot of water a few days before the test. Just 5 days after eating an edible, 80 to 90% of THC gets flushed out but the remaining 10% can be detected for up to 4 weeks. THC metabolites can be detected in sweat for about one to four weeks.

- Headaches, like most other symptoms of withdrawing from marijuana use, will usually begin one to three days after quitting and peak two to six days after stopping.
- This is drawn out to around one week for a more sensitive 20 ng/mL threshold.
- Detectable amounts were seen up to 12 days after THC exposure in more frequent users.
- As I’ve said, there are several popular cannabis testing methods and passing them depends on the testing method and the frequency of cannabis use.
This indicates that the current effects of cannabis, including withdrawal, may be more extreme compared with their effects in previous decades. Over the years, based on samples of confiscated cannabis, potency has steadily increased. The THC content has risen from around 3.8 percent in the 1990s to 12.2 percent in 2014. Weed, or cannabis, is the “most commonly used illicit drug in the United States,” according to the Centers for Disease Control and Prevention (CDC).
Support for Quitting Marijuana
Although conventional wisdom says at least 30 days, the answer is not straightforward. There are many different kinds of drug tests available, which have varying levels of sensitivity and time periods to detect marijuana in your system. Medical News Today says first-time smokers may have cannabis detected for “about 3 days,” while more consistent smokers at three to four times per week can have it detected for “5-7 days” afterward. Daily smokers can expect tests to detect weed for at least 30 days. The most common standard urine drug test can detect THC up to 90 days after inhalation/ingestion. Does that mean that everybody who has smoked a joint in the last 90 days will test THC positive?
- THC traces last the longest in hair tests, and it could be several months before you test clean.
- Hair follicle tests can detect weed for up to 90 days after last consumption, for most users.

Blood tests can detect THC metabolites for several days to a few weeks. Upon inhalation, active THC can be found in the bloodstream within seconds and detected in plasma for several hours, depending on the frequency of use and dosage. Different drug tests for cannabis have different detection windows. In general, detection time will be longer with a higher dose and more frequent cannabis use. Additionally, tests can detect THC for longer periods in individuals who use cannabis products more frequently. This is because chronic cannabis use will result in THC accumulating in fatty tissues, which will result in a slower elimination of metabolites.
How long is weed detectable on a drug test?
- Hair tests can detect THC metabolites for as long as 90 days and increase with frequency of consumption.
- For example, when you eat a cannabis brownie, it takes much longer to get “high” when compared to smoking.
- Therefore, it’s essential to know how long weed can be detected in your system.
- Yet, these alternatives, commonly referred to as “K2” or “spice,” are unpredictable, showing side effects ranging from nausea to seizures that have caused a spike in overdoses in recent months.

It’s also affected by your unique physical functions and frequency of consumption. This inactive metabolite is stored in body fat and gradually eliminated or metabolized. It remains in the body far longer than active THC, which is why so many cannabis detox drinks and kits claim to eliminate or mask the presence of THC metabolites. Blood tests typically detect recent cannabis use or use that has occurred within the last 2–12 hours.
Physical weed withdrawal symptoms tend to be less intense, peak sooner, and fade more quickly than psychological symptoms. One person’s experience with marijuana withdrawal can be quite different from another’s. However, there are some cannabis withdrawal symptoms that are more common, the severity of which depends on a host of factors, including frequency of use and overall health. Daily smokers experienced the most cannabis withdrawal symptoms. But even those who reported using marijuana less than once a week experienced weed withdrawal symptoms of moderate intensity.
