Cocaine and Urine Drug Screens

  1. 0
    Does anyone know how soon and how long it takes for cocaine to show up on a uds after it's used and how long it will show up on one, i.e. it will continue to show up 1 day or 1 week or 1 month after it's used?

    The only drug that shows up for any length of time in a drug screen is pot. You can find the info online. I'm pretty sure cocaine clears pretty quickly.

    I know because I had had a rare lapse and smoked pot about a month before applying for a new job that required a drug screen and I found all the info online. Ironically, pot, the mildest drug stays in your system the longest, the other ones clear relatively quickly.

    Unless they check your hair. Then anything you've done in the past 6 or so months shows up.

    Misinformation city lol.


    A google search will give you the specifics, but as a general rule *Most* things are not detectable after about a week (but everyone is different and metabolizes said drugs differently). Marijuana is the exception, something about being fat soluble, but again it depends on the person, it might stay detectable by the standard UDS for 2 weeks or >month.

    As far as the hair test (which I have never heard of any facility using), it depends on hair length, if you have hair down to your waste and it doesn't grow very fast I imagine they could test several years in the past. But again, I have never heard of any facility ever doing a hair test.

    No it is not as misinformation city as one might think.

    Do a search on this site for hair and drug screens and you'll find the thread regarding this topic. It is not years though and has nothing to do with the length of your hair. Its in the follicle. And its up to 90 days >.

    Hair Analysis
    This information is based on a written consensus opinion from Society of Forensic Toxicologist, Inc. on applicability of hair analysis for drugs of abuse. Their concerns focused on consistency of detection of drugs and interpretation of the results and the application of the testing procedure based on the necessitating circumstances. The biggest issue was quality control.

    The advantages:

    Less invasive procedure in obtaining a sample.
    Longer detection window, up to 90 days for most drugs of abuse.
    Ability to detect true break down products of certain drugs (cocaine and marijuana) in confirmation of internal exposure.
    Ability to assess chronic drug use over an extended period of time.

    Well I was going by what you said, "Unless they check your hair" Then "anything you've done in the past 6 or so months shows up "

    I think I misunderstood what you were trying to say, I thought you were trying to say a UDS can detect things up to six months.

    UDS or Blood Tox screen does now show any drug if you last used it 6 months ago.

    :chuckle A correctional officer told my nurse friend that if you drink lots and lots of orange juice you can get a negative drug screen. I don't know if that's true or not but my nurse friend and I sure had a lot of fun teasing each other about being sure to drink a lot of orange juice before coming into work.

    I personally don't use cocaine. I would NOT trust OJ with my career

    Hopefully noone here uses any recreational drug including pot, which has negative effects on one's short term memory. If anyone is using drugs or abusing alcohol, get help!!! We've lost two nurses in the past two years because of these problems...
