Cannabis in Your System: For How Long is it Detectable?

There several reasons for wanting to know how long marijuana and its effects last in your system. Maybe you have a pending drug test, or you’re simply interested in studying the psychoactive and metabolic influences of weed. Being in the know is very essential especially when you desire to steer clear from any possible adverse ramifications should a drug test produce a positive outcome. Similarly, understanding how extensive the weed’s psychoactive effects can be in your system helps decide how frequently to use it and the perfect timing for your sessions.

The question of how long marijuana may remain detectable in your system has no direct answer. In most people, large amounts of marijuana may be detectable in the system in not more than 30 days, and often, traces of the substance are gone in as little as 10 days. For one to determine a detectable date with precision, they have to take into account the period of drug use as well as specific drug test to be used.

The most commonly used weed detection tests include:

1. Urine Tests

The urine test is very commonly used to detect marijuana use based on its ability to tell a person who has used it even after the drug’s psychoactive chemicals in their blood no longer exist. It means that, while you may not be “high” on weed during a urine test, you may still be found to have used it. A single weed smoking or eating session may be traced via urine 7 days after using. Regular use can be detected in anything from a week to 100, it all depends on how regular one is using. For moderate use, the weed detection period via urine falls below 30 days, usually.

2. Blood Exam

Blood tests have a lower efficacy duration compared to urine tests. If you’re a repeat marijuana user, a blood test can give you away in 2 to 7 days since your latest session. But if you use just once, a test won’t find any marijuana traces in your blood after 24 hours.

Hair Test

Usually, hair never tests positive for marijuana for single-use people. However, a hair test may track marijuana in repeat users numerous months after their last session. Heavy use may actually be detected in hair years later.

Reasons for Different Detection Timeframes

Detection periods for urine and blood samples differ because the tests are not looking for the same marijuana component. Urine tests look for THC-COOH, a non-psychoactive substance that’s the outcome of marijuana metabolism. On the contrary, blood screening detects THC, the “high-inducing” chemical in cannabis. So, any test that seeks to detect weed impairment focuses on blood, and not urine.
