How Long Does Weed Stay In Your System

You may have wondered how long traces of cannabis use can stay in your system and
there’s always ‘that guy’ who will tell you he knows for sure it’s this long or heard about
somebody saying it’s that long or whatever. The facts are that cannabis can be traced in a user’s
blood, urine, hair and saliva but there are factors in each individual user that can alter the
duration cannabis remains in the body. And to be very specific – it is commonly believed that
tests are looking for THC but that isn’t entirely the case. THC does not last for more than a few
days in user’s bodies so the test are looking for something a little more specific called
THCCOOH which can last for more than three months in some cases. So, what are the factors
that effect individual tests:
First off is frequency of use: it stands to reason that frequent everyday users will have
traces present more prominently and for longer duration than infrequent or first-time users.
Dosage is important. Obviously the more you ingest or inhale the more likely it is going
to show up in a test.
Physicality of the user is a big indicator of duration the cannabis can stay in your system
as well. If you are a big guy with a slow metabolism you’re not as likely to have the same results
as a little gal with a banging metabolism if you are both ingesting or inhaling the same amount of
Exercising impacts the body’s ability to detoxify the system so if you are an ardent
exerciser THC will dissipate in your system faster than a couch potato’s.

Overall health of the body is a big factor in metabolizing cannabis and if you, specifically
your organs, are in great shape your body will expel the toxins quicker. The liver is the primary
organ that processes THC and the better condition it’s in the better it will function and the
quicker cannabis byproducts will metabolize in your body.
And some of the more obvious considerations on testing the duration that weed will stay
in your system is the test itself. How sensitive is it? It is possible to have remnants of THC in
your system and still pass some tests while others are more exact. The method of testing is an
important factor as well. Test results based on urine, saliva, blood and hair offer varied rates of
So, just how long does weed stay in your system? Here’s the lowdown to help you figure
