Klonopin has a long half-life, which varies between 18.7 and 60 hours. That means that it might take between 4.29 and 13.75 days for the drug to leave the system of the user. In other words, one might need up to two weeks to get clean from Klonopin.

Can One Be Tested Positive for Klonopin?
Klonopin is a powerful benzo, and as such, it can be detected by various drug tests. Blood, swab and urine tests can detect the drug for up to 5-6 days, while hair tests have a longer window of detection, up to four months. Note that acidic environments can help to excrete the drug quicker.
How Long Does Klonopin Stay in The System?
Klonopin or Clonazepam is a habit-forming and life-threatening benzo. Therefore, users should be aware of the duration and the elimination of the drug. Its half-life ranges between 18.7 and 60 hours.
These figures suggest that it might take between 5 and 14 days for the drug to leave the system of the user.
In other words, one might need up to two weeks to get clean from Klonopin.
Factors That Affect Klonopin Duration & Excretion
As we can see, nobody can predict how long Klonopin will stay in one’s body. Some users need only a few days to get clean, while others – a couple of weeks. That’s because each case is unique.
In general, we can say that the following factors determine how long Klonopin will stay in the system:
- History of intake
- Polydrug abuse
- Body mass
- Overall health
- Food intake
- Urinary pH
However, many individual factors can affect the duration and the elimination of the drug.
Note that patients with hepatic problems may need more time to clean their system from Klonopin.
Klonopin Metabolism Process
One of the important factors that affect Klonopin duration and elimination is the metabolic rate of the user.
The drug undergoes hepatic metabolism. Note that less than 2% of Klonopin is excreted unchanged in urine.
Last but not least, we should say that Klonopin binds to plasma proteins and fat stores, which leads to extensive distribution in the system.
Klonopin & Drug Testing
Although Klonopin is a potent benzo, testing for it is not common. However, various tests can detect the drug.
Remember that one needs 5-7 days of consistent administration to reach some steady levels within the body, even small doses can lead to positive results.
How Long Does Klonopin Stay In The Blood?
Blood peak concentrations can occur as soon as one hour after intake. Therefore, the best time for a blood test is 1-2 hours after ingestion.
However, blood tests can detect the drug as soon as few minutes after intake for up to few days.
Note that as these tests have a short window of detection and are quite invasive, they are reserved mainly for hospitalized patients.
How Long Does Klonopin Stay in The Hair?
Hair tests provide a long window of detection, up to four months. Thus, hair tests can reveal a lot about the history of abuse.
We shouldn’t forget that the best time for a hair test is few days after ingestion as it takes some time for the metabolites to appear in hair segments.
How Long Does Klonopin Stay in The Saliva?
Saliva tests are a great option in the case of intoxication.
That being said, detecting Klonopin and its metabolites in oral fluids is more difficult compared to other tests.
Swab test can detect the drug for 5-6 days after intake, with a cut-off level of 1 ng/ml.
How Long Does Klonopin Stay in The Urine?
Urinalysis is the most preferred method for the detection of Klonopin and its metabolites.
Urine tests have cut-off levels of 30 ng/ml and can detect the drug for up to 5 days after intake.
Some studies claim that users may test positive for up to 30 days after their last dose.
Note that some acidic foods can help to excrete the drug quicker.
Still, the best way to test negative and stay safe is to say no to Klonopin abuse.
