Drug Test Detection Times
What to do if I have only smoked 2 times in the last 2 years. most recent was 7 weeks ago will I pass a hair drug test?
Was it one episode?: In “Pharmacokinetics of Cannabinoids” by McGilveray IJ it is stated “Hair tests are more likely to detect regular than occasional marijuana use. One study found that 85% of daily users tested positive for marijuana, versus 52% of occasional smokers (1-5 times per week). ...Read moreSee 1 more doctor answer

I have only smoked weed 3 times. I only smoked a little 2 days ago and I have a drug test on Wednsday, will i pass?. Im 5`0 and 106 lbs.
4 days to clear: A reference I found stated that infrequent users (like you) should likely fall below the 50 ng/mL threshold at four days. Frequent users could clear in as little as 10 days; but extremely heavy users may not clear until 2 months. Hope that helps. ...Read more
Whats the time detection difference with home drug test and test from labs with specialized equipment?
Depends: The elimination time for various drugs is very different. Whether one considers a test to be positive or not, also depends on the threshold for the positivity. Lab tests are more sensitive than home tests, but it is not feasible to provide a general statement of the time difference for detection by the two methods for the multiple drugs of abuse. ...Read more
I smoke marijuna but I only hit it 4 times in the morning and night I didnt smoke Tuesday but got a blood drug test done Wednesday eveningevening...wi?
Will be positive: If you're a regular user, and it sounds like you are, THC will show up in a blood test for up to 3 days. Urine tests may be positive for the marijuanas metabolite THC-COOH for up to 30 days. Consider submitting another question to us: "What are the health effects of long term, regular marijuana use on my health?'" That's something else you need to know. ...Read more
I have a drug test tomorrow morning. I am 5'2 125 pounds. I'm 33 days weed free. I drank and excessive amount of water over the 33 days, and ate right, for the most part, and stayed semi active. I smoked maybe 2 to 3 times a week, less than a gram (normal
Hard to say: My best guess is that it is likely to be negative, since only very heavy smokers (usually daily or 5X/week) who have smoked for months/years stay positive for over 30 days. However, it depends on the quality of the marijuana used (how much THC) and for how long you were smoking it. Congrats on quitting. Stop excessive water use since a dilute urine specimen will be considered adulterated. ...Read moreSee 1 more doctor answer
Drug tests: It is probably a combination of the tester using a cheap, lower sensitivity testing kit, testing during a low level of the drug in your system and you being a fast metabolizer. Oxycodone has a half life of about 3-4hrs. If you test several hours after your last dose the levels in you urine may be too low for the test to pick up. Also, only a small amount of the drug appears in the urine. ...Read moreSee 1 more doctor answer
I used Vicodin about 5 times 2 months ago, will I pass a hair drug test?. My hair is about 1 and a half long. I am relatively fit.
Too soon: It's too soon to be certain to pass. It can be up to 90 days for a hair test. Sorry. Here's info: http://www.passyourdrugtest.com/timetable.htm But, if you have a valid Rx - it's wrong for anyone to hold that against you. Obviously, you know that w/o one you should not take that stuff, right? ...Read more
