Weed, also commonly known as marijuana, is a recreational drug that has gained increasing popularity in recent years. It contains chemical particles called THC, which enter your bloodstream when you consume weed and can stay in it for a prolonged period of time. Blood drug tests represent one of the most widely used methods of detecting THC. They are used in a variety of situations, from employment procedures to child custody cases. It’s extremely important to understand how long weed can be detected in your bloodstream. This knowledge will allow you to make informed decisions regarding weed consumption and avoid the negative consequences of failing a blood drug test. This article will provide a clear answer to the question “how long does weed stay in your blood stream?” by explaining how blood drug testing works and the factors that influence weed detection times. We will also provide you with practical recommendations on how to beat a blood drug test.
Understanding Blood Drug Tests
As we already mentioned, the consumption of weed leads to the accumulation of THC in your bloodstream. Blood drug tests are specially designed to detect this residue and determine whether you’re a drug user. The testing process involves taking your blood sample and thoroughly analyzing it in a lab. We should also note that this type of testing is commonly used in various situations due to its high accuracy and reliability.
How a Blood Sample is Collected
A healthcare specialist or lab worker will collect your blood sample. This process includes the following steps:
- Cleaning a spot on your forearm with an antiseptic
- Wrapping a tight elastic band around your upper arm
- Inserting a needle into your vein
- Drawing your blood into a small tube
- Labeling the collected sample for a THC blood test
Substances That Can Be Detected by a Blood Test
- Weed (marijuana, THC)
- Alcohol
- Cocaine
- Amphetamines
- Opioids
- Barbiturates
- Benzodiazepines
- Oxycodone
- Methadone
- Phencyclidine
- Propoxyphene
Blood Drug Test Timing and Results
Modern labs usually analyze collected blood samples within 1-2 days. In urgent cases, they can perform an analysis on the same day. A positive result means that drugs were detected, while a negative one means they weren’t. We should also warn you that blood test results will show both which substances were detected and their levels.
When and Why Do Employers Drug Test?
Due to the increasing popularity of weed as a recreational tool, drug testing has become a common procedure in the modern workplace. Most employers believe that drug users tend to be absent-minded, irresponsible, and prone to making mistakes. Thus, hiring them could lead to decreased overall productivity and workplace accidents. Moreover, certain industries have to comply with strict anti-drug laws and are simply forbidden from employing drug users.
As you might have already guessed from reading this information, employers use blood drug tests to maximize operating efficiency and avoid legal liability and potential financial losses. They are also a common part of pre-employment screenings and post-accident investigations. These tests are especially widely used in such industries as transportation, construction, healthcare, security, sports, and the military.
Additionally, we should note that you may have to pass a blood drug test in various legal situations, such as those concerning probation or child custody. Thus, you can be forced to undergo blood testing by legal authorities like courts or probation officers.
How Long Does Weed Stay in Your Blood? How Far Back Does a Blood Drug Test Go?
It depends. THC can stay in your blood for different periods of time based on a variety of factors. These include the frequency of weed consumption and your personal characteristics such as weight, metabolism, etc. For starters, let us look at how long THC can stay in your blood based on consumption frequency.
Consumption frequency |
Weed detection time |
Single use |
1-2 days |
Occasional use (3-4 times per week) |
Up to 7 days |
Regular use (daily) |
Up to 15 days |
Heavy use (several times per day) |
Up to 30 days |
As we already mentioned, THC can be detected in your blood by a drug test based on several factors, and one of them is the consumption method. For example, THC enters your bloodstream very quickly when you smoke weed, but it accumulates in your body much slower when you consume edibles. Such differences produce a significant impact on weed detection times. You can see a detailed table illustrating these differences below.
Consumption method |
THC detection time in blood |
Smoking |
1-3 days for occasional users, up to 7 days for regular users |
Eating |
Up to 5 days for occasional users, up to 10-15 days for regular users |
Vaping (vax pan) |
1-3 days for occasional users, longer for regular users |
We would also like to briefly talk about different types of drug tests that can be used to detect THC in your system. While blood tests are usually used to detect recent weed consumption, employers and legal authorities often rely on urine and hair tests to determine whether you consume weed because they offer much larger THC detection windows. Let us look at weed detection times for different types of drug tests.
Drug test type |
Detection window |
Blood |
12-24 hours (up to 7 days for heavy users) |
Saliva |
24-72 hours (up to 7 days for regular users) |
Urine |
Up to 30 days |
Hair |
Up to 90 days |
What Factors Affect How Long Does THC Stay in Your Blood?
We have briefly mentioned that the amount of time for which weed stays in your bloodstream depends on a number of factors. Now let us look at them more closely. The following list will give you an answer to the question “how long does marijuana stay in your blood?” based on your personal characteristics.
- THC Dosage. Higher THC consumption leads to its accumulation within the body. Logically, it will take more time to get rid of larger doses.
- Frequency of Use. The more frequently you consume weed, the more THC accumulates within your body. Occasional users will find it much easier and faster to get rid of weed residue compared to regular and heavy ones.
- Body Mass Index (BMI). THC is stirred in your fat cells. Thus, people with high body fat retain it for significantly longer periods of time.
- Metabolic Rate. Metabolism influences how fast your system can get rid of THC. A faster metabolism is equal to a faster purification of your body.
- Hydration. Maintaining a proper level of hydration will allow you to flush out THC faster.
- Exercising. Physical activity allows you to get rid of weed residue and toxins. If you have a sedentary lifestyle, doing so will take much longer.
- Age. In general, older people need more time to get rid of THC.
- Health Condition. If you have chronic health conditions, it may take you longer to fully cleanse your system.
