One limitation of the study is that it did not look at which types of cannabis products people used or the strength of those products. Also, because the study focused on young adults, the results may not apply to other age groups. However, the new study adds to the scientific evidence that long-term cannabis use how long does weed stay in your system may affect cognitive abilities, including memory.

The accuracy of hair follicle testing for THC is often debated due to various factors that can affect the results. So, if you’re wondering how long weed stays in your hair, it’s important to consider that hair drug testing can detect drug use for up to 90 days. This means that even if you have stopped using weed for a while, a hair drug test may still show positive results. For occasional users who consume marijuana infrequently, traces might only be detectable for about 30 days post-use.
Conclusion – How Long Does Weed Stay In Hair Sample?
- Whether you use marijuana for recreational or medicinal purposes, understanding how long does marijuana stay in your system helps you prepare for drug tests or plan your health decisions.
- A urine drug test has some drawbacks, and one of them is detection window.
- Additionally, environmental exposure to THC can also affect its retention in hair.
- Most urine tests can identify 5 to 50 nanograms of THC-COOH per milliliter (ng/mL) of urine.
Tetrahydrocannabinol (THC) is the main component responsible for the euphoric high you get when using marijuana. Over time, THC stored in your body’s tissues and organs is released back into the bloodstream. Then, of course, not everyone’s hair grows at the same rate, so it’s possible that your hair may rat you out for drug use far past the 90-day date if your hair grows slowly. This connection remained even when researchers excluded people who had used cannabis recently, based on the urine test. The results also weren’t affected by how much alcohol participants reported drinking, researchers found. People also provided urine samples on the day of testing, which were used to determine if they had used cannabis recently.
- Anything above that pretty much confirms you’ve used marijuana in the past three months.
- This phase can last anywhere from two to seven years, depending on individual factors such as genetics and overall health.
- The likelihood of getting a false positive from a blood test is low.
- It’s essential to be aware of this when considering drug use, especially if you have a job or other responsibilities that require drug testing.
- One way to help protect yourself is to apply for your medical marijuana card to ensure that your cannabis use is documented as medical and share that with your employer.
Frequent Cannabis Use May Damage Working Memory, Decision-Making Skills
- We’ve discussed the lifespan of THC in hair follicles, how your body metabolizes cannabis, the various detection methods, and more.
- Those with faster metabolism have higher chances of clearing weed the fastest, while those with slower metabolism have prolonged detection windows.
- This means that a person who smokes several times over several days has consumed a higher THC dose than someone who smokes once, so they are more likely to test positive.
- While legal in some states, it can be disallowed in job situations.
- With edibles, the effects can take much longer to kick in — usually between 30 minutes and 2 hours.
- Again, the level of marijuana in the body significantly depends on the amount of THC in it.
Using certain cannabis products with a high concentration of THC results https://ecosoberhouse.com/article/10-celebrities-who-died-because-of-alcoholism/ in more metabolites and by-products. These by-products are stored in the body as they bind to the fat molecules. The metabolites also circulate in the body in the bloodstream and reach your hair follicles, getting deposited in the hair shaft. When you use marijuana, the main active ingredient – THC – is absorbed into your bloodstream and processed by your body. Once THC enters your system, it’s distributed to different organs and tissues, like the brain and liver. 1 These metabolites are what stay in your system long after the initial effects of the drug wear off.
It helps to penetrate the inner layer of your follicles and remove the drug residues. This factor will also significantly affect the weed survival time. With age, the body’s processes also slow down, and it might get more challenging for the system to expel the drug efficiently. The more this compound is present in a person, the darker their hair is.
I was not only interested in working memory, but I wanted to see how cannabis affected a range of different drug addiction treatment brain functions, so we looked at seven tasks,” he added. In particular, Yafai is concerned that people who use cannabis for chronic pain or to help them sleep may be turned off by the way the results of this study are presented. In the new study, researchers examined data from the Human Connectome Project, which explores how age, growth, disease, and other factors affect the connections in the human brain.
Frequently Asked Questions About Weed Detection In Hair and Other Drug Tests
More activity and increased metabolism times can mean your body fully processes and excretes cannabinoids from your body. Urine tests are one of the most common methods for detecting weed. THC can show up in urine for varying amounts of time, depending on how often you use it. With occasional use, THC may be detectable for 1 to 3 days after use. With moderate use, it may take 7 to 21 days for THC to clear from the urine. Daily use, especially by those who have used marijuana over a long period, can test positive for up to 30 days or more.
A 2017 study reports on testing where hair samples from 136 cannabis users self-reporting heavy, light, or no use of cannabis. For the study, researchers cut hair into 1-centimeter sections to test for exposure up to a month prior. When THC enters the body, it is metabolized into a byproduct called THC-COOH, the substance detected in drug tests to give a positive result. The body can store this byproduct in places like fat cells for weeks or months. A process called immunoassay screening will be done to detect drug metabolites. If it is positive, which means the drug is present in the sample, the quantity of the specific drug will be measured by a more precise test called gas chromatography-mass spectrometry.
