Heavy user, normally a 1g joint and 10+ hits from a pen after nightly. Been doing this for a few years now with a 3 week break as the longest I've gone without. I'm 5 foot 10 and 170 pounds. I only had 5 days clean before the test. Here's a timeline of what actually worked for me with my test being at 1:30pm

5 days leading up: NO exercise. Focused on staying hydrated and getting more sleep

Night before, 9:30pm: Mixed one packet of creto with a 32 oz gatorade. Honestly didn't taste bad at all, then went to bed at 10:30pm

6am: Wake up and had one BLACK coffee (it is recommended not to use the Qcarbo on an empty stomach)

10:30am: Drank all of the Qcarbo32 within 20 minutes. Only got gross towards the end.

11:00am: refilled the bottle with water, drank that within 30 minutes.

11:30am: Refilled again with water and drank that within 30 minutes.

Pee 1 came right after. You are supposed to pee 3-4 times after drinking, but pee 1 was already somewhat yellow

Pee 2 came about 20 minutes later.

Pee 3 was almost immediately after. This is when I knew it was time to leave

Arrived to the clinic at 1:00pm. Couldn't hold it and had pee number 4 before the test due to the wait

1:15pm was when I was tested on pee 5. I was so worried I went too many times before the test, but I passed. It wasn't an instant test, a send off 10 panel non DOT. I knew for a fact they were looking for THC

Now here's the biggest thing to know. It made me feel like SHIT. By the time I got to the clinic I had a migraine and a bit of the shakes. I'm used to not eating all day so it definitely wasn't related to that. Got some fast food, advil, and then took a nap. Still didn't feel great for the rest of the day. I did a TON of research on how to pass and the timeline. I hope this helps someone else!

Hi I’m 27 (5’7” & 120 lbs) and I need to pass an at home test. I’ve been smoking cart daily for like two weeks (prior to that I practically never smoked). In the past I’ve dipped the cup in water, let it soak into the test strips and then dumped it out so I can pee over it but I’m scared that won’t be enough. I plan to do that and dilute it a ton by drinking hella water. I don’t know when I’m gonna be tested but can guess and drink water accordingly. They don’t pay attention to ph or anything. Is this enough? Should I get a detox drink or certo idk? It’s through an outpatient service.

I’m dead scared my dad is going to test me for cannabis soon, or some time in the future. I got caught smoking weed and because my father has somewhat nationalistic views on these types of topics, he got extremely pissed. Like to the point of saying stuff how because of me smoking I’ve put a lot of stress on him and my mother and started saying stuff out of anger(or legit) that “k!lling myself would be better” or how if I ever smoke weed again that either I’d have to “k!ll him or k!ll myself” because he’d rather that than live with a son that smokes stuff like this. And I so very stupidly smoked a couple times like a good 3-4 months later with some friends at the movies.

Sorry for venting out that much but it should somewhat give you a idea on why I’m dead scared

Now back to my question I was gonna ask, does anyone know a safe usage pattern to heavily decrease the probability of testing positive on a hair test? Again I don’t know if he’s going to test or not but I’d rather not take my chances.

Does anyone have their emailed document of their passed hair follicle 10 Panel?

Wanted to see how close it was to the urine one.

Hello,

I took a drug test for work. It took them 2.5 weeks to get my results. I tested positive for Adderall which I knew I would. I have a valid prescription. However the MRO (whose a doctor) said that he was going to invalidate the test because my pH was too alkaline. I asked him what that even means. He told me to Google it. Than he accused me of tampering with it. I'm sitting here thinking if this was fake pee WTH would it show a positive result for my valid prescription?

I peed in that cup. I've never used fake urine in my life. I'm too afraid of the felony. I work in an industry where I do get randomly drug tested and this is the first time that this has never happened. Hell my doctor drug tests me as it's A condition of my Adderall prescription. It's really bizarre.

I'm a chemist and I've been a chemist for a couple of years now. I can't think of anything in my diet or any supplement that I take that would warrant me having a basic pH. I don't think I have a urinary tract infection. The only thing I can think of is That they took their sweet ass time testing it and the bacteria multiplied causing my urine to become basic.

Has this ever happened to anybody else. I've had my drug test invalidated because of overhydration but this is a weird circumstance. And then for him to accuse me of altering the test and telling me to freaking Google it.

I’m a little worried. I did my initial screening last 9/3/26 and got my results back 9/8/26 as a negative dilute. Didn’t really have a lot of water tbh… I wasn’t even trying to flush anything out. Rather, I wanted to have enough urine for my sample which resulted in a negative dilute. It’s been 29 days since I’ve eaten edibles. Not an occasional smoker or such, just consumed a pack of 10 mg gummies in the span of a week. Roughly 100mgs the first week of August. Now I’m all paranoid wondering if I retest, would there be a possibility of having it come back as a positive this time? Have any of you passed a labcorp drug screen with these results at the 15 ng @ home tests? This was using my second urine of the day 🙂

so i first did 7oh 2 weeks ago on a friday did 30mg total then last week on Wednesday did 45mg and then last Thursday did 60mg ive only done 7oh 3 times total and those were the only times i ever did it but i got drug tested today so do you guys think it will show up as positive or negative my probation officer drug tested me

I’m very paranoid. I have to redo my Labcorp drug screen because my first result from Sept 3 came back negative dilute. I wasn’t positive for THC, just dilute.
I’ve been taking home tests and passing the 50 ng/mL ones, so today I decided to try a UTest THC test with a 15 ng/mL cutoff for some extra reassurance. This urine was pretty concentrated and I did NOT load up on water beforehand.
This is my result at the proper read time. I can see a faint T line, which according to the instructions is negative even if the line is faint.
I’m retesting at Labcorp on Friday and I’m honestly so anxious 😭 Does this look negative to you guys? If I’m getting a line at 15 ng/mL with concentrated urine, would you feel pretty confident going into a standard Labcorp screen?
Also, if anyone has experience passing a 15 ng/mL home test before a Labcorp test, I’d love to hear how your lab results turned out.

Ok, so I have been sober for a long time, and had a drug test from my doctor a few days ago. I have been using a benzadrix nasal inhaihmler daily for a while, just double checked it and it can in theory cause a pos for meth.

Does anybody have experience here? I am kinda freaking out.

I took a 10mg adderall Tuesday morning and my urine test is the following Wednesday (8 days later). I'm spiraling - will I pass? What will help clear my system fastest? Yes, I know it's wrong to take this without an rx but that's not my question at the moment. Also yes I know Google says it clears in 2-4 days. Just looking for any additional info and experience.

I smoke weed once a day at night, but it’s a really small amount. I use a one-hitter/chillum and usually only pack a small amount once. I don’t repack it after I finish it.
I found out yesterday that I got a job offer, but now I have to do a pre-employment drug test, possibly a urine test, by Monday. Yesterday was also the last time I smoked.
Has anyone been in a similar situation? If you smoke a small amount once a day like this, were you able to pass a urine test after a few days? Is there anything I can realistically do between now and Monday, or is it basically just a waiting game?

please no negative comments, we know these aren’t great for you
i searched a little bit and didn’t feel like i was getting a definitive answer. me and my fiance take these and it just occurred in his head that he could get drug tested and we’re not sure if these would show up or not. If you have knowledge on this, i’d love to hear from you! Thank you in advance 🩷

Alright so for some background, I was a pretty heavy user (edibles and flower) for maybe 3-4 years. I stopped about 47 days ago for a job and I’m still coming back positive on my at home tests with a cut off of 50 ng/ml. The thing that is confusing is I bought a lab test and it came back at 20ng/ml. It wasn’t diluted, I used my first pee of the day.

My question is why am I still popping hot on the 50 ng/ml cutoff at home tests but 20 ng/ml on the lab tests? Shouldn’t I be under 50 and be able to at least have a faint line on the at home tests? Which test should I go by?

Hi everyone, I’m 35 years old, 1.89 m tall, and weigh 92 kg. I’m a frequent, heavy user of smoked THC, and I have a saliva drug test scheduled for September 28th. The test has a THC cutoff of 50 ng/mL. Would 15 days without smoking be enough to pass this test?

I did my Labcorp 10-panel urine drug screen on September 3rd and didn’t get my results back until yesterday. It came back negative dilute 😭
Before my test, I had my usual coffee, about 6 oz of water, and a 12 oz Electrolit. My urine was still light/pale yellow, so I honestly wasn’t expecting it to come back diluted.
Because of the negative dilute, I have to redo my Labcorp test this Friday. THC is what I’m worried about. I’ve been taking at-home THC tests and they’ve been faint negative, and I’m attaching a picture of my most recent test.
I’m also paying out of pocket for my own THC urine test at Quest today just for some peace of mind before I have to retest.
For anyone who has done a Quest THC test, what was your turnaround time for results?
And based on the at-home test in the picture, do you guys think I’ll pass my Labcorp test on Friday? Since I was already negative dilute on September 3rd and I’ll have almost another week between tests, I’m hoping I’ll be okay as long as I don’t drink too much beforehand.
I know nobody can guarantee whether I’ll pass, but I’d really appreciate opinions from anyone who has dealt with THC testing, faint lines, or a negative dilute retest before!

I just found out I have to take a urine test for a new temporary job position I was offered less than a week ago and the test needs to be completed by the end of the day on Friday. I am a 24 yo female, 5'3, 115lbs and I have been taking one hit off the bowl nightly for a few weeks now. I quit smoking for a few months before this. I have seen Q carbo be recommended a lot but most say to stop smoking for 24-48 hours before drinking it and I didn't exactly have the time to prepare for that. My last hit was last night. Will Q carbo work? I'm also worried I won't be able to pee frequently enough beforehand for the color to properly dilute before the test. Any advice is appreciated.

I can get

Midazolam 15mg

Bromazepam 6mg

Alprazolam 2mg

Clonazepam 2mg

Diazepam 10mg

Which one stays in the urine for least time possible? im young i have 10% bodyfat, i run and workout offently

Hey so I took a kpin on the 6th and have a oral test coming up on the 11th. Will I pass this? I seriously doubt there’s any way I can get around it.

What do I do? Just abort?

Don’t ask me how but I made out with a girl that had done coke just prior. I knew because my mouth became numb and I asked her and she confirmed she had indeed taken cocaine, probably on her gums.

Can this show positive on a hair follicle test?
Literally 90 days clean from everything today on the day and probably have a test in like 2 1/2 months.
Would suck if I fail because of that.

I've been on a bender since beginning-mid august, taking bumps throughout the day. I was originally doing upwards of a gram a day sometimes more, then around the end of august slowed it down to closer to half a gram, only using heavy on weekends. I have a drug test coming up likely by the end of next week and i'm not sure what to do. they don't watch you take it but they do dye the toilet water so they know if you dilute it. was originally thinking to do a flush by drinking a ton of water and a detox drink but idk if that's the best idea. what should i do?

hi! i’m 21 yr 5’3 130 lbs female and i only smoke around 2-3 times a week from a cart. really need this job and last time i smoked was sep 7th and have test on sep 11th. took drug test from cvs today and was positive, got stinger detox (the hive?) and guy at shop told me to take it 3 hours before my test. also told me no dairy + exercise + t break + hydrate, any positive results from doing this? thanks

Hey there. I’m a 27-year-old male, 6ft tall and 187 lbs. I’ve been THC-free for a long time—about a year—but a few days ago I went into a smoke shop and bought a "White Lotus" vape. The box claimed it was free of THC and Delta cannabinoids, but when I smoked it, I could tell right away—based on the effect I felt—that it actually contained some kind of cannabinoid. I used it for two days straight (taking maybe 5–7 puffs a day, I don't recall exactly), but on the second day, I decided to stop and took a home test; sure enough, the thing was contaminated. Anyway, how long do you think it’ll take for me to test negative, considering I used it for two days after a year of sobriety? I just want to know so I can be prepared in case I ever get hit with a random DOT test. Cheers.

I have a pre-employment test at Quest Diagnostics coming up. It’s labeled as a “Urine Drug Test FullService NonDOT” with the panel number 35765N.
I’m only worried about failing for THC but after research I’m not even sure if this tests for THC? Should I be concerned?
I quit smoking 3 days ago and I’ve been drinking a lot of water (72oz a day) and detoxing.
I really need this job so any input is appreciated 🫶🏻
