j wilson eyes wide open

My name is Jay Wilson, but my friends call me JZ for short.

Originally from Atlanta, I now live in Denver, CO where things are a bit ‘freer’ these days. During the day, I code websites and mobile apps for a living.

I put this site together for a friend who asked me to search Google to answer his question one night about drug tests.

He was scheduled for a hair drug test at work the following month, and wanted to know if there was any way the test could be beat.

I tried Googling ‘hair drug test’ and found some older forum posts plus LOTS of hot air and junk sites pushing various products and services.

The worst part was I was doing all of this on my Samsung S4 – and none of the sites I found were remotely useable on my phone!

After a few minutes of getting frustrated, I decided to spend much of the following week researching the subject completely. Then, I put up a new mobile-friendly website with what I learned so others in my position won’t get frustrated with the crap out there on the web. This website is the result.

All of the methods, products and services I mention on this site must have plenty of documented, authentic happy customers – or I won’t list them.

Best of luck on your next hair test!

– JZ

    this has been great information. I have smoked within the past 90 days and a job I really want is asking for a hair drug test with Psychmetrics. Is what you have described really works? I have Hair Toxin shampoo. Or am I fighting an uphill battle and have no chance in passing.

    Hey Jay!

    Can someone smoke say couple hits a couple times a month and it still not build up enough to pass through to hair?

    What about just a couple hits 1 time a month?

    Just trying to figure out what amount can be smoked semi-regularly without risk of failing – of course abstinence should be the name of the game ha.

    Any insight would be appreciated.

      Smoking more than 3 times over the prior 90 days, and you start to risk testing positive. Sorry, but THC is really stubborn that way.

      I would be surprised if you fail.

    Hey JZ,

    Great stuff on this site, thanks for putting it together. You really have helped back off the cliff the last couple of days. That being said, wanted to run by situation to your community to see what you think.

    Accepted big time job offer; contingent on “successfully completing a pre-employment screening” (some ambiguity with “successful”).

    Physique: 6′, 215lbs, ~25% body fat. Dark, thick hair. Decent amount of body hair (that never gets cut). Hispanic of European descent. Slowish metabolism. Have been doing HIIT spin 3 times/week for about 2 months now.

    Been about 7 years since I was a regular weed smoker. Smoked about a blunts-worth (don’t remember the exact quantity) about 2 years when I was visiting a friend in Seattle. Visited that same friend this past August (end of the month) and smoked again (the novelty of legal weed just got to me). Potent stuff, ~27% THC and ~6% CBD; two blunts about 1g each. First sitting (~12pm), I smoked about 50% of one by myself. Split the rest with my friend later that night (~9pm). Next night we smoked about the 40% of the other blunt. That amounts to roughly smoking one, 27% THC blunt over the span of ~32 hrs. Been clean since.

    On 10/10/17 I got a hair cut, leaving the longest section about 1″ – 1.25″. Was not anticipating a drug test at the point (actually got a hair cut for the interview).

    I had my hair follicle test on 10/24/17 (didn’t read the order and assumed it would be a piss test….I know, fml right). The collector sampled the back of my head near an area that my hair fades a hair cut from about .25″ to about 1.5″. After some careful inspection, my girlfriend was able identify the collection spot and noticed that some of the hair sample was not taken directly to the scalp and maybe a .25″ or so were left.

    I know there is nothing I can do at this point but the suspense is killing me. Also, thought I would provide a data point on whether I pass or not. Biggest concern with getting a positive result is the potency of what I smoked. I am also not sure about whether the quantity and time lapsed between uses can be considered as a single use.

      Wow, thanks for the detail – it helps. I’d say you’d be fine after smoking one blunt in the past 90 days – except for that 27% THC concentration… kinda equals 2-3.

      Given this, I’d say you are at risk but still on the better side of passing.

      Let us know how your test turned out!

    Asking for a friend here, thanks in advance:

    6’3 265 lb. Male
    Light activity
    Slower Metabolism
    Hair is short and light brown

    2 hits of MJ from vape pen 110-130 days ago
    1 MJ joint smoked (low potency) 80-90 days ago

    This guy hasn’t done any other drugs or things like this in ages and hasn’t touched anything since, except a few cigars. He is freaking out because he has a couple tests coming up:

    Hair test – do you think he passes? Probability?
    Urine – do you think he passes? Probability?

    Also – do you think it is necessary for him to do extreme hair treatments? Anything else you would recommend?

    Thanks for helping this suffering person…

    Thank you,

      No, I don’t think your friend is at risk of failing a hair or a urine test. Best of luck to him!

    I may have to do a pre-employment screening mid to late January. I had a weekend where I did a couple lines of coke each day with the last use being on December 20th. What would you recommend? If I buy the old style aloe toxin rid shampoo, do I need to wait untilright before the test to cleanse my hair. I would like to use a home test to insure the shampoo worked before I get screened by the employer. If I fail there is a potential I could lose a license to work in that field so it’s high stakes. I’m really trying to gage if i need to not take the test and turn down the job. Also I was considering buying the shampoo and also using the macujo method. Any input helps. Thanks!

      Given your situation, I’d def. try the Macujo or Jerry G. Do the procedure several days in a row right up until the day of your test.

      Wishing you the best possible luck on your test…
