Understanding how long a cart stays in your system is essential for anyone preparing to pass a drug screening.
However, the answer isn’t the same for everyone, as factors like the frequency of use, the user’s metabolism, and body mass influence how long vape substances stay in the body.
Let’s delve into how long a cart stays in your bloodstream, the detection window for various types of drug tests, and the variables linked to THC detection time in one’s body.
A weed cart is a pre-filled cannabis oil or concentrate cartridge, designed specifically for use in cannabis vape pens. Unlike smoking a joint, vape carts offer a smoke-free way to consume cannabis. They are known for delivering concentrated doses of THC directly into the bloodstream, offering potent effects. THC from a cart can linger in your system longer and be detectable in various drug tests.
Those who hit a cart wondering “if I smoke every day, how long till I’m clean?”, the answer depends on many factors that affect how long it takes weed to leave the system.
How far THC can be detected in your system is influenced by individual body chemistry and the type of drug test administered, such as blood, hair, urine, and saliva tests.
These drug testing methods usually work by detecting THC metabolites that can be stored in the fat cells and slowly released into the blood over time.
Here’s the breakdown of different drug test methods to screen for THC or THC by-products in the body, with detection window:
Though blood test has a shorter detection window compared to other drug tests, they can detect fairly recent cannabis use. Blood tests can usually detect cannabis use for 2 to 12 hours after consumption.
However, heavy and chronic users may show positive drug tests beyond 12 hours as THC is stored in the fat cells. So, they can have detectable levels of THC in their blood for up to 1 month after consumption.
For a single use, THC is typically undetectable in the blood after 12 hours. For instance, if you are an occasional user and smoke once a week, the THC level may not be detectable 24 hours after consumption. Regular users may test positive for THC for up to 7 days or longer.
Hair tests are considered a more reliable method for detecting regular THC use. They offer a longer detection window because THC binds to the hair shaft from the bloodstream and stays there for an extended period.
A hair follicle test can detect THC and its metabolites for up to 90 days. For this test, about a 1.5-inch segment of hair is taken to check for cannabis use over the past 90 days.
Hair typically grows about half an inch within 30 days, but the rate varies from person to person. That’s why this test cannot determine the exact time of consumption, even though it can detect cannabis use over a longer period than urine or saliva tests.
Urine tests typically have a longer detection window and depend on how frequently you use THC. So, the detection time can vary from a few days for occasional users to several weeks for heavy or chronic users. A research review found that THC can remain detectable in urine for the following durations after stopping use:
Frequency of use | Detection Window |
Single use or infrequent use | Up to 3 days |
Less than 3 times a week | Up to 7 days |
Daily use | Up to 2 weeks |
Multiple use in a day | More than 30 days |

One study shows that the more you consume cannabis, the longer it stays in the body.
Saliva test provides short-term THC detection and is popular for roadside testing for detecting recent use of cannabis. In some cases, this oral cannabis test can detect same-day weed use.
For infrequent users, THC remains detectable for up to 24 hours in a saliva test. This review indicates that THC in frequent cannabis users is detectable in a saliva test for 72 hours after stopping use. One study suggests that THC levels may be detectable in the saliva for up to one week after last use in chronic users.

Below are some of the determining factors in terms of how long the cart stays in your system:
Detection windows are largely the same whether you’re smoking, vaping, or eating edibles, but frequency of use can significantly extend how long THC stays in your system. The length of time THC from a cart remains detectable is shorter for occasional users compared to regular and heavy users.
Your metabolism determines how quickly THC is broken down and expelled from your body. Users with higher metabolic rate may be able to eliminate THC faster than those with a low metabolic rate.
The potency and dosage with higher THC concentration and how much you consume in one session may affect how long THC metabolites can be detected in the body. If you take THC in higher doses, it will stay in your system longer.
THC breaks down into metabolites that are fat soluble, which means they bind to fat cells and slowly release into the bloodstream. People with higher body fat might store them longer, and they remain detectable for a longer time.
Not all drug tests have the same level of sensitivity. The sensitivity and accuracy of the testing method can influence how long THC and its metabolites can be detected. Highly sensitive tests may potentially extend the detection period, as they can detect minute levels of THC metabolites.
