How Long Weed Stays in Your Blood System?

One frequently asked question among weed users is how long does weed stay in your blood? Various drugs linger in the body for a given amount of time. With weed products, there is the possibility of a lengthier residual availability in your body. 

Depending on several factors, the length of weed lingers in your blood system will also vary. Strain is one of the facilitators, with hybrid strains such as the Lemon Cherry Gelato being present longer than low potency strains. There is no definitive indicator for what strains will stay longer in the body than others. 

Though the effect of cannabis may seem to wear off in several hours, it does stay in the body for longer. Through tests via urine, blood, and even hair strands, it is easy to identify if someone has taken any form of weed in the past. This is all possible but to a given time frame. 

Determinants of Weed’s Residual Presence in the Body

As mentioned, there is more than one reason for how long weed stays in your body. The body of factors that go into prolonging the detection of cannabis varies from issues such as genetics to the frequency of use. 

These are the most common factors.


Granted, some people won the genetics lottery, and their bodies have such fast metabolism rates that everything gets processed out of their bodies fast. This also applies to weed. People with high metabolism rates will have cannabis in their systems for shorter periods than those with slower ones.  

Potency of Strain

Some strains have incredibly high THC levels, meaning the body will take longer to cleanse itself of its effects. Other strains have such low potency that the weed levels are not detectable in the body after a few days. 

Frequency of Usage

Frequent users are more likely to test positive for cannabis in their blood than infrequent users. It all comes down to the body’s ability to clear the THC components and at what rate. With frequent users, the body is dealing with a build-up of cannabis in the blood; clearing it will take longer. Infrequent users with almost ‘clean’ blood do not need a prolonged time to remove the weed from their blood. 

Method of Intake

Compared to smoking, edibles leave their mark for longer in the body’s system. The method of intake varies, and so does the amount it stays in the body. 

How is Cannabis Detected in the Blood? 

There are several ways through which weed detection in the body is possible. The mode of testing determines how long the weed is detectable. The three standard methods of testing are; blood, urine, and through hair strands. 

Blood Tests

Does cannabis show in blood tests is one of the common questions on search engines. The detection of cannabis on blood tests is overly possible. There are blood tests that can detect weed in your system up to 1-2 days since your last use. 

The same is influenced by the factors stated above. For instance, the weed can be detected even 25 days after their last smoke by chronic users, which means several smokes a day. 

Urine Tests

Urine tests are the most common ones. Most users try detoxing from weed whenever they hear their companies will be conducting urine tests. Its detection rate covers from 3 days after use to 30 days after use, depending on its frequency. While a single use is only detectable within 3 days, chronic users are detectable even 30 days after their last use. 

Hair Strand Tests

Lastly, hair strands are a more effective method of detecting weed in someone’s system. Testing a hair follicle can reflect weed usage for up to 90 days in the past. Another less popular testing method is the use of saliva. Its inconsistency has resulted in the unreliability of the same. 

Weed Residual Present in your Blood

Most users often wonder about the residual impact of smoking weed. How long it stays in the body and whether it is detectable via blood tests are some of the questions that they ask. It takes more than the frequency of use and type of strain to determine precisely how long the cannabis will remain in one’s body. The information above clearly shows that each user’s experience brings on a different residual presence. Also, depending on the testing method, a person can have their last use detected from 1-30 days.
