How Long Will Marijuana Take to Get Out of the Body?

Q: Hi, my name is Matt. I had been using marijuana daily for 7 months. However, recently I have stopped. I have 32 days today clean. I took a urine screen 7 days ago and tested positive for marijuana (THC). I have been given 30 days to get a clean urine. I have another screen in 4 days which will give me 36 days clean. It has been difficult to stop using pot. I used 2 joints daily to help relieve stress, and it worked. However, now I cannot have it in my urine, so I’ve stopped. I have 32 days clean from any use period. I can’t tell you how frustrating it is to have went through this daily struggle to get clean and still be testing positive. Like I said I have another test in 4 days. Is it likely I will still test positive? Is there any test I can have done to show when my last use was? This is very frustrating because everyone I know is saying you should definitely be clean 30 days after use. I absolutely have not used and I am still testing positive. What can I do?

It’s very good that you have stopped using marijuana. This drug is addictive, and leaving it abruptly just proves you to be a very strong individual.

Though these drugs are anxiolytics in action, it is always better to be a controller of your brain yourself, not let anything else take control. Never take any such drug again, let your mind be healthy always.

Consume plenty of fresh fruits and vegetables for quicker cleansing of your system.

There is no single accurate answer for the length of time marijuana stays in our body. The excretion time varies from 3 to 90 days!

This is because there are many factors which influence its excretion.

Factor Affecting the Excretion of Marijuana From the Body

They include:

  • Your body weight and body fat percentage. This drug gets stored in the fatty tissues of the body. This makes its excretion slow as compared to other drugs which are not fat soluble (hence not stored in fats of the body).
  • Marijuana may stay for long time in fatty tissues of the brain, liver or kidney and is slowly released into the blood stream to produce effects.
  • Your metabolic rate: The faster is your metabolism, the drug will get out of your system quicker.
  • Fluid intake: Consuming more of water and other fluids can help in speedy excretion of the drug.
  • The type of drug used: The neuroactive substance present in marijuana is THC. The amount of THC present is different in different varieties of marijuana.
  • Degree of exposure to the drug: Chronic user find it more difficult to remove the drug from the system than one time users. This is because the drug gets collected in fatty tissues and adds up each time it is taken.
  • Your overall health and physical status: If you are healthy and physically active, your body would be able to remove the drug more efficiently.
  • Method used to detect the drug: Blood tests are very sensitive even till 2 to 3 months. Urine tests are of many types. Some toxicologist measure THC in urine while some measure metabolites of THC, which are detectable for even longer periods.
  • Consumption of alcohol impedes the excretion of this drug.

Though most of the drug must have been washed away from your body, traces are still detectable. This is because the drug collected in your liver and other fats over months, is slowly being released into the blood stream.

You have to be patient. It may take another 15 to 20 days to get completely out of your body.

      You need to be very aggressive with your detoxification to wash off this drug in such a small time period.

      If this was a one time use of the drug, it is possible to clean it till 2 Oct. However, if you have being using the drug often, cleaning is difficult.

    I smoked .5 grams of good THC 29 days ago. I have a drug test in 3 days. This was first time use. I drink regularly but the last 2 weeks only beer and only a few times. Have been drinking water 1 to 1.5 gallons a day for the last week and a half except the few days I drank beer which still made me urinate a lot. I am overweight but have been exercising heavy cardio a few days a week for last 2 weeks. For the last 4 days I’ve done heavy cardio and will continue the next 3 days until urine test. Will I be clean?
