    Would 1g of cocaine be out of someones urine in 11 days for a drug test including all metabolites while assuming normal body fat, metabolism, BMI, liver function, hydration level, etc?

    Honestly, I would personally by a little worried, but that's just me. I would probably avoid foods rich in sugar, fat and caffeine.
    Consumption of food rich in vitamin B and juice fasting or water fasting diet for 5-7 days continuously, also seems to be really helpful.
    If you have a sauna at a nearby gym, I would definitely take advantage of it. Also, get some exercise. Good luck!

    Re: is 11 days enough to pass a drug test?

    the metabolites that are tested for (even with a MS/GC) are undetectable after eleven days.
    They are undetectable because THEY ARE NO LONGER PRESENT.
    11 days is more than enough time to pass a drug test (hair sampling excluded only because I am not an authority on these types of tests)

    this is for cocaine

    Re: is 11 days enough to pass a drug test?

    Thank you for your reply bobes, I just called him hes really excited with your news, you seem to know your shit and its the answer hes been waiting for, he had the test today. just one more question. Would lots of alcohol intake push it past 11 days for any reason?

    He quit weed 2 months ago for this job and seemed to pick up the slack with alcohol. He gets drunk every weekend thurs-sunday and has a few beers after work during the week. Hes got a high metabolism and doesn't gain weight
    One more thing i know he never did a full gram it was at most a 0.7-0.8g, he got a few lines from his buddies for free when he was blacked out drunk.

    no amount of alcohol or thc will affect a screen for cocaine

    Re: is 11 days enough to pass a drug test?

    nope... I used to use alot (every day for many months) and SWIM once failed a urine test at 6 days... this happens sometimes with chronic use.. after this, SWIM always would wait 9-10 days to be absolutely sure... at 11 days I couldnt imagine anyone testing positive unless they were using massive amounts.. (SWIM once read about someone failing after 14+ days but this si purely anecdotal...)

    Re: is 11 days enough to pass a drug test?

    halo99,
    i respect that you have an opinion and personal experience that I can't TRULY challenge because there is no way for me to disprove your claim.
    However, there is no data or research that i am aware of to support your experience.
    Could you provide some non-anecdotal evidence to support your claim.
    As a former staff therapist at Canada's Centre for Addiction and Mental Health CAMH (our nations largest treatment and research facility), i worked with cocaine addicts (both crack and hydrochloride) many of whom would use more than ounce or more a week for months at a time before ending up in my office as a result of hospitalization or incarceration.
    NONE of my patients tested positive for cocaine after 96 hours with a GS/MC.

    I offer you the following link to support my statements. I am strongly encouraging you to find evidence to support your claims which I find so erroneous i want to scream. this information is so harmful in so many ways.
    I look forward to your response!!!

    please refer to line 8 ON PAGE 398. perhaps you should read the whole article but that line would be enough.
    first time uploading a pdf hope this works!!!

    Re: is 11 days enough to pass a drug test?

    look up "Detection Times of Drugs of Abuse in Blood, Urine, and Oral Fluid" by Alain G. Verstraete

    specifically this passage:

    Cocaine
    The usual intranasal dose varies between 20 and 100 mg,
    but it can be much higher in heavy users. The half-life of co-
    caine and benzoylecgonine are 1 and 6 hours, respectively. The
    detection time of cocaine in blood is 4 to 6 hours after 20 mg
    and 12 hours after 100 mg.32 In serum, in chronic users, ben-
    zoylecgonine (BE; LOD 25 ng/mL) was detectable for 5.1
    days on average (maximum 8.6 days).22


    Obviously my own story is anecdotal so it must be taken with a grain of salt but i do take issue with you implying that my opinion is 'harmful' I am merely suggesting to err to the side of caution... in todays economy many people cannot afford to lose a job over a failed urine screen... If i was suggesting that 2 days was enough then i could see your point but rather the opposite...

    halo99 added 6 Minutes and 9 Seconds later...

    Also i should note that the findings in the noted study specifically addressed the variability in different individuals metabolisms... in addition to this there have been advances in MS detection techniques that actually can detect smaller amounts of metabolite (although i doubt that many tox-screening labs are using them).. as you noted GS/MC or FTIR are still the gold standard for detection...

    Halo,
    What an excellent response!
    I believe that one of the purposes of this excellent site is to encourage dialogue and debate and I think you handled my "challenge" wonderfully.
    The information in your references does not match the experiences in my practice or those of my colleagues.
    In thousands of tests I have never seen or been shown positive tests results for cocaine after 96 hours.
    So, i will continue to have confidence in the research that indicates cocaine detection after 96 hours is approaching impossible. (renal conditions excepted). However, this comment can be considered "anecdotal" without me providing client case data - which is impossible due to confidential restrictions.

    The Toronto Drug Treatment Court continues to use a 72 hour detection window and will revoke bail of TDTC participants if they show positive for cocaine after 72 hours of "reported last use".

    Thank you for participating in this dialogue.

    I need to add that my "harmful rant" was not only unnecessary but truly "out of line" in this instance. Please accept my apology and Ill stop making "universal judgements" at 4 in the morning!

    the tests he took were 35105N CD51-5P/THC50 and 39209N OXYCODONE (U) SCRN; would these fall under the GC/MC tests?

    Re: is 11 days enough to pass a drug test?

    no problem... i actually agree with you that for the majority of people 96 hours is likely enough for the benzoylecognine metabolite to fall below the threshold of detection... in fact before i failed that time i had always waited 4.5 days and tested negative... then positive result happened and i have been playing it way safe every since...

    halo99 added 10 Minutes and 11 Seconds later...

    those are codes for the standard quest 5 drug panel + THC + nitrate/createnine so its the strip test where they pour a sample of the urine into a test vial and then insert the set of strips which give the preliminary results.. if they all test negative and it tests negative for dilution/adulterants then you are good to go... if a positive result is seen then i believe they follow up with GC...

    GC is only used to absolutely confirm a positive result for non-criminal testing (e.g. like for a job...) the testing that bobes describes is court ordered so i believe they use GC for everything due to the higher evidentary standards...

    Cocaine is primarily detected as Benzoylecgonine in the urine and is detectable for 1-4 days in urine at typical detection limits (50-300 ng/mL). Chronic users of Cocaine may have increased windows of detection.

    I was going to make an account on this site to ask this question but then he found this thread. I was worried about a urine screening for army selection a month after doing half a line of coke, because after he read about metabolites he got very worried. I took a lot of alcohol with this blow so he was worried about it being retained.

    I am worried that alcohol will retain these metabolites for up to a month, is this likely?

    Whoever this SWIM may be (please dont use this acronym, click on the link on the first 'SWIM') he will be fine after a month.
    Half a line of coke - whatever 'that' may be - but I get the picture - will not make anyone dirty for longer than makiximum 6 days, alcohol added or none.
