Is weed/marijuana detectable after 2 weeks?

Asked by chokolatcake (111points) January 27th, 2012

I would like to know if weed/marijuana is still able to be detected after 2 weeks (having 2–4 hits) through a urine test?

Definitely. That sticky icky is in your pours never-mind blood for up to 3 months.

It is held in your fat tissue. And yes it may take weeks to be eliminated for sure.

@Boogabooga1…the hell? Read that sentence. Read it and tell me it makes sense.

Times are heavily dependent upon the amount taken, the body size of the smoker (mostly concerning fat) and on the frequency of smoking. A heavy user with a lot of fat tissue could (possibly, I stress possibly) have a positive test up to 30 days after having last smoked.

Urine tests can be less reliable than blood tests, and the same heavy user may only test positive up to maybe 7 days.

Not 100% on marijuana, but have seen a single dose of cocaine detected in a hair follicle sample for as long as it takes for the hair to grow out. Kind of like rings on a tree, only lengthwise

Yes, its definitely possible, if not almost certain. It depends mostly on the regularity of smoking and your body type.

However, with a good regimen of flushing and detox, you can rid your body of cannabinoids within 2 weeks, even if you’re a regular smoker. I wouldn’t cut it any closer than that.

If its a blood or hair test, you’ll probably test positive regardless.

“A single use of cannabis may be detected by a typical urine drug test for 1–6 days depending on amount smoked, individual body metabolism rates, and the cutoff level used by the test (15 ng/ml, 20 ng/ml, 50 ng/ml, 100 ng/ml). Chronic or daily use may be detected by a typical urine drug test for 7–30 days depending on the same factors listed above. Lower levels of Cannabinoids do remain in the body for longer than 30 days, but appear unlikely to result in a positive drug test due to cutoff levels.”

“Some THC metabolites have an elimination half-life of 20 hours. However, some are stored in body fat and have a elimination half-life of 10 to 13 days. Most researchers agree that urine tests for marijuana can detect the presence of the drug in the body for up to 13 days.

However, there is anecdotal evidence that the length of time that marijuana remains in the body is affected by how often the person smokes, how much he smokes and how long he has been smoking. Regular smokers have reported positive drug test results after 45 days since last use and heavy smokers have reported positive tests 90 days after quitting.”

I know a lot of weed smokers (and personally I think it should be legalized) so I know from their experiences that you could test clean after two weeks. To speed up the process, drink a lot of water and try to lose a few pounds. The combination of losing a few fat cells and flushing with water will help. Your personal metabolism is a big factor.

a week atmost

If you have an important test to take, you can always get a home test from the drug store beforehand.

After 2 weeks yes. But I do agree with the few on here that pointed out that body fat and frequency of smoking are a big factor.

Run boy, run! Sweat out your toxins go straight hell week mode on your body and you’ll be fine within a week. You have to be drinking a bunch of water though.

@auhsojsa Run like he’s running from the cops?

I’d certainly think there is a good chance of it being detected, but if you are concerned just stay clean for 3 weeks in advance.

It really depends how often you smoke it. If it’s your first joint, it will be undetectable after a few days. If you’re a regular user it will take weeks to clear your system.

You only smoked once? And took 4 hits? I’m pretty sure it won’t show up 2 weeks later. If you on a daily basis smoke and stopped 2 weeks ago, it probably will show up.

samantha360's avatar

If you only took a couple hits it’s out of your system pretty quick but if you smoke a lot it will stay in your system for about a month.

It depends on a person’s body fat percentage and metabolism level. If your reasonably thin with little fat then you can clear an urine test (without cheating) in as little as 3 days (for the amount of THC they test for), even with regular use. This can vary still and another factor is the strength of the weed/hash as well when it comes to THC content and the frequency of use.

I would suggest drinking plenty of water (minimum of 1 gallon per day) and exercising/staying physically active. Then you want to back off of physical activity within 2 to 3 days of taking the test. The goal is to flush as much THC that you can out of your system and then keep what little THC levels are left in your body dormant by avoiding physical activity, which increases THC levels in the bloodstream and in your urine. Try to stay inactive while drinking plenty of water a few days before giving a specimen of urine for testing. Unfortunately there are no gaurentees here but this system has worked for most people that I knew.
