This is the number one question people have been asking when they are first getting started with using Cannabis.
Truthfully, there is no one definitive answer to this question and we’ll tell you why — everyone is different.
A large number of factors come into play when talking about THC levels, so unless the test is done by a lab via a blood test, results can vary.
Many people are also unaware of the fact that urine drug tests do not test for THC, but instead, test for THC metabolites such as THC-COOH.
When you use Cannabis, THC is converted by your liver into THC-COOH, which stays in your system for quite a while – storing itself in fat cells. When your body breaks down this fat, it releases the metabolites into your bladder, which is why urine tests are a very inaccurate and outdated form of drug testing.
These days in a post-legalization Washington, drug tests for Cannabis are measured using blood samples, which are much more accurate for testing active THC (the kind that gets you high). Metabolites found in urine may show signs of a person using pot within the last 60 days, but it is not an accurate measurement of impairment at all.
That means those myths of chugging tons of water or using some sketchy urine mask products are probably not true. Exercising excessively before a test is also not recommended, since it releases those fat-stored metabolites into your blood stream, setting off the test.
Regardless, even if you tried to mask the cannabinoid metabolites using these products, the person administering the test would know something was up.
The best most consistent way to pass a drug test: Stop using Cannabis for a few weeks.
It’s hard, but just imagine how wonderful it will feel to become lifted again after a short break!
If you want a general idea, there is a time scale according to a study by the National Drug Court Institute.
According to the chart above, THC can remain in your system as follows:
- A new or infrequent user (two or three times a month) – Positive for 1 to 4 days after using, could be longer
- Frequent users (two or three times a week) – Positive for 10 – 12 days after use
- Every day users – Positive for 60+ days or more
