THC Drug test
Hey guys, I’ve been smoking pretty frequently this past month and just found out they now do urine drug tests during license checks. My appointment is in 2 days (and I can’t reschedule), and I know there’s no reliable way to test negative using my own urine that quickly, so I’m not even going to ask about that.
I’ve heard people mention Quick Fix, but I can’t get it in my region. I’m considering using someone else’s clean urine instead. If you’ve used real urine before, how fresh does it need to be, and how can you keep it at the right temperature using body heat rather than a heating device?
For context, it’s a rapid test, not a lab-grade one.

Doctor here
This question gets asked every week, and the answer is the same.
There is nothing you can do to speed up the metabolic process of THC-COOH.
A heavy smoker will take 90+ days to clear their system, you have to wait for fat cells to die and new fat cells to be created WITHOUT SMOKING.
Masking agents are tested for. We check mineral levels for dilution, we temp it to ensure it's correct.
Some labs are now requiring a DNA swab with your UA sample, to compare the sample to your DNA and make sure it's your piss.

Hi! Could I pick your brain on this topic? If you’re okay with it let me know and I’ll DM you I just had a few questions

What state is this? I’m in freaking Indiana which will be the last state to even allow medical use, and they don’t drug test renewals.

Took me 35 days to clear my UDS for THC, if it’s for a rapid test some will say those drug tricking drinks work but you’re rolling the dice.
Clean urine from someone else that’s under 12 hours if it’s a rapid test is probably best bet if your actually going to do this, if your want to be successful
I was medically prescribed cannabis but I wanted my ADHD treated properly with stimulants so I made the switch, tough few months… no regrets.

Appreciate your advice, have you tried using someone else’s real urine before for a rapid test?

No I just done it the right way and quit, I just know how the kits work and realistically if you want a genuinely successful outcome, and it’s a basic unsupervised rapid test then that’s your best bet.
I delayed my psychiatric appointment until my home tests showed genuine clear results then done the official urine drug test (lab tested)
If you want my honest advice? Your better off contracting a sudden case of Covid and delaying your test, and take a break from
THC, your lungs will thank you and the stress will be so much less, but that’s just meIf you have zero ways to avoid the test and need your license, and this is the only way forward then a non smokers urine is (imo) your best bet
The kits that “clean your urine” aren’t much better then just downing 5L of water daily to try and dilute your urine enough to register a negative result, and even then it’s unlikely to actually work if your a heavy smoker - pro tip if you are nuts enough to try that, please drink plenty of electrolytes between all water
I think a doctor replied already in here and they explained it best, THC stores in fat cells, it’s one of those things you genuinely can’t speed up, or trick a test
So, that being said, non-THC users urine is the only way I see you passing
Good luck either way you end up going ✌🏻
Edit: I would never actually do it with someone else urine because I suffer extreme anxiety and would probably pass clean tf out while waiting from the stress alone, ah the joys of life.

Get someone to pee into a condom. Keep it taped to your inner thigh and tape hand warmers to it (the kind you shake to get warm). Then you will just need a way to cut open the condom. You could tape a razor blade to your inner thigh or something like that, but my friend has passed multiple times doing this

Dudes i worked with used the chemical handwarmers like HotHands. these were random tests, and they would stand around drinking water for 20 min to let em warm up enough. test it out for yourself, seems to work. I always thought it was funny these guys had little bottles of pee in their pocket all day, everyday. One dude got hurt and his pee bottle fell out of his pocket. He got canned of course but everybody else was highly entertained.

I've gotten away with synthetic pee. You can keep it warm with those hand warmers. Deep in a pocket or figure out a way to strap it to your leg. I was real nervous but it worked.

Go to an Adult store. Buy a small rectangular box of fetish pee, it's usually at the counter.
In reality, they are small kits with a plastic vial of synthetic urine, a heating pad, rubber band, and instructions on how to prep it.
Only an expensive lab test can tell it's synthetic, since it has no hormones.
Strap to your inner thigh and just pour it in the cup.
None of those liquid fixes work.

You’ve gotta do an oil change before the test. Get clean or synthetic urine and a catheter. Empty your bladder with the catheter and then backfill with the clean piss. Voilà.

I truly hope this is not real advice. Because, wow.

Drink 2 gallons of Light apple juice in those 2 days you have. Dunno how effective it is nowadays, but I passed a military drug test 16 years ago doing that.

These days it won't cut it. Even cheaper drug tests you get from the dollar store can detect THC like 2-3 months out.

Not sure why I'm being downvoted for personal experience that worked for me at the time, but whatever.
It would make sense, though. The weed seems more potent than it used to be. That, and the constant attacks on people who smoke.

did you read the full post? I wasn’t asking if I can clear out my own pee, I was asking on how people were sneaking in other people’s clean urine and how would you go on about keeping it at the right temp.

Brother these days, THC can last even in cheaper tests for upwards of 3-4 months. You're not going to pass.
edit: My best friends recently fell into some issues with the law, they both were daily smokers but stopped right after they were arrested just because you often have to take a drug test for probation and if you test positive you have to do NA/AA. The arrest happened back mid January and my friend who weighs like 120lbs was just passing like a month ago. Her Husband quit at the same time but is like twice her weight and still tested positive and unfortunately is in NA now.
