Cannabis in Your System: For How Long is it Detectable?
From different perspectives, it makes sense to be aware of how long marijuana and its signs may last a user’s body system. Maybe you have a pending drug test, or you’re simply interested in studying the psychoactive and metabolic influences of weed. Getting the facts right is important as you need to take care and avoid any potentially undesired consequences of a positive drug test result. Also, when you know how long marijuana’s psychoactive influences last in your blood, you can plan well your smoking (or ingesting) sessions and the frequency of use.
The question of how long marijuana may remain detectable in your system has no direct answer. Many individuals have weed remain in their system in substantial quantities for detection in a month or less, and mostly, any signs of the substance may disappear in just 10 days. It’s only possible to predict a detectable duration of time after assessing how long an individual has been using the drug and the nature of drug test to be administered.
Here are some of the main approaches for testing cannabis use:
1. Urine Tests
Urine is one of the most commonly used weed testing method because it can detect that someone used the substance long after its psychoactive elements are no longer traceable in their blood. As such, a urine exam may reveal that you used weed even if you’re not “intoxicated” with the substance during the test. 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 exams are useful for a shorter period than urine testing. For frequent users, blood tests may reveal marijuana use within 2 to 7 days after the last time of use. But if you use just once, a test won’t find any marijuana traces in your blood after 24 hours.
The Hair Method
Usually, hair never tests positive for marijuana for single-use people. However, the test can detect marijuana months after use in case of frequent consumption. Years on, extreme consumption may be found via hair tests.
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. Therefore, blood, as opposed to urine samples, is the better measure for cannabis intoxication.
