How long does weed last in your System?


Cannabis or weed is one of the most widespread chemical compounds globally. It produces euphoria in individuals allowing them to relax and feel better.

Its legality status varies across different regions but is legal in the U.S. People are increasingly using weed, leaving weed detectable in their system fluids for 1 and 30 days.

It’s understandable if you are confused about its lasting because it is subjective. For example, traces of weed may be detectable in hair for several months (especially for frequent cannabis users).

Various factors determine the weed detection window in the body, so weed smokers should understand how it works. Let’s dip into it.

How long is Weed Detectable in Drug Tests?

THC or delta-9-tetrahydrocannabinol is one of the most commonly found compounds detected in people using weed frequently. The drug tests usually calculate the number of metabolites in your body or the by-products. These metabolites can stay within your system even weeks after you have consumed weed.

The duration for weed detection varies for individuals depending on the amount of smoke they intake and the kind of drug they use. For example, urine testing is the most popular drug testing method. The traces of THC by-products can show up in your fluid tests. The exact duration varies on your use frequency.

Daily: 10 to 15 days

Four times per week: 5 to 7 days

Multiple times per day: more than 30 days

Single-use: 3 days

So, weed users need to evaluate their individual use and then determine the lasting of weed in their bodies. The main reason the metabolites from weed last so long in the body is that they are fat-soluble.

They can dissolve or bind with the body’s fat molecules and take time to leave. The metabolites may also last longer in your system if you have more fat in the body.

Are Blood Tests and Saliva Tests the Same?

The blood tests can only detect recent weed use in the body, primarily for up to 12 hours. However, heavy weed smokers may still show traces of metabolites in the system after 30 days.

Saliva testing is one of the quickest methods to determine current cannabis use. Some studies show that traces of oral THC was still prominent 72 hours after administration. So, oral tests may show THC traces for longer than normal blood tests.

Thus, law enforcement agencies perform saliva tests in states where weed is not allowed. For more severe cases, they might even require a hair test.

The hair test usually shows weed detection for up to 90 days in the body, as the cannabis reaches the hair follicles through the sebum and sweats our surroundings.
