Kratom and Drug Tests

I recently got a job offer hinging on a drug test, so I stopped smoking weed for a while and got some 14 panel home drug tests to make sure it was cleaning up beforehand (still dirty, got about a week before the drug test, getting kind of nervous but the job is in a legal state so I'm not sure weed is what they are even looking for but its only safe to assume they are). Turns out it will be a 5 panel at a lab.

But here's the thing, I take kratom pretty frequently and the 14 panels I bought have been coming up positive for buprenorphrine. The only drugs I have used in in a good long while are weed, kratom, kava, alcohol, and mushrooms, obviously its not the weed, kava, alcohol, or mushrooms.

The lab offers a standard 5 panel and a 5 panel with expanded opioid testing. I'm not sure which version they are going to have me take and the expanded opioid version doesn't specify what other opioid they look for other than oxy, but implies its more than just that.

I have a few questions:

Is the kratom I've been getting possibly laced with bup or is bup a known false positive from kratom? How can I find out for sure if kratom from this vendor is laced or not? I'm not totally against taking bup, but I do have an issue with taking it unintentionally.

Assuming they give me the expanded opioid version of the 5 panel test, is bup/kratom going to present an issue? Is taking kratom/possibly bup slowing down the process of thc leaving my system?

I don't smoke too much weed, I go through maybe .25g/day, occasionally more, still positive after about two weeks of complete abstinence from just weed, should I be concerned about being positive after another week? The drug tests I got have a 50ng/mL threshold, I'm assuming the lab test is 15ng/mL. What can I do to speed up the process?

Edit: meant to update, my state has legal protections against employers declining or ending employment based on THC use. Still a little concerned they might try, but technically I could sue if they did, so I think they are probably just making sure I'm not on other drugs. Not sure why I didn't look that up sooner.

The odds of them lacing kratom with bupe are extremely low. Lets say they have low quality kratom and are trying to enhance it with something to make it appear stronger, Adding bupe would just make the kratom basically inactive. They'd be better off lacing it with something like O-DSMT or some other opioid RC like they did in the past. How much kratom have you been taking? I'd bet my bottom dollar that the kratom itself is somehow causing a false positive for bupe. I don't think that this is common, but if this is happening with the drug tests that you've bought to use at home then they may not be as high quality as ones used by a lab. I doubt that bupe shares any metabolites with Kratom so not sure why it'd cause a false positive, unless theres some sort of endogenous chemical caused by bupe usage that is also caused by kratom. If you get a false positive at the lab, I assume that you can request to have it sent in for analysis in which case they'll be able to see that it was a false positive. I had to request my samples get sent to the lab 2 or 3 times when I was doing treatment because I kept coming up positive for morphine. Turns out I had very trace amounts in my system due to me eating a couple of poppy seed muffins a week at the time.

Have you looked up a list of medications that can cause a false positive for Buprenoprhine and made sure that you aren't on anything that does?

And I personally would be concerned with weed still showing up after one more week. I have no clue what you can do to speed up the process. .25g/day is not a large amount by any means, but it is still daily use and that still does add up over time. You can always try the fake urine

Thanks, that's what I figured but I'm not an expert. With new job/move stress and quitting weed, I've been going through more than normal. Can't say I know how much exactly but probably close to 12g/day inconsistently.

I have tried searching but I haven't found anything definitively. The only other thing I've been taking at all medication wise is ibuprofen here and there and that doesn't seem to be a cause. The only thing I've found is morphine, which I tried maybe once over a decade ago.

I'll see if I can figure anything out before my drug test. I still have one more home test and plan to check again before the real one. Thanks! Dilution/reschedule might be a good way to go. It would be very believable that I would be drinking extra water anyway since I'm moving to a hotter climate. Also a legal area, so not sure it'll be an issue at all even if I am positive. I just don't wanna bank on that.

Sounds like a plan! I'd definitely try to drink lots of water. I have heard that if it's TOO diluted that it's an automatic fail, but considering that this is for a job and not legal reasons then maybe it'd just be cause for a reschedule. You can also always try to old home remedies like cranberry juice, vitamin-c and exercise.

I have also heard good success with fake urine but I think that it depends on the place and you have to be really good about making sure that the temperature is correct. Are you in a state where weed is illegal? I'm in a legal state so depending on the job they might not care about a little bit of marijuana.

When I was doing outpatient treatment and had to take UAs for my buprenorphine, I'd often test positive for marijuana. I was just honest with them and told them that I used CBD weed for anxiety and sometimes to get to sleep because I have insomnia. They didn't really mind so long as my THC levels didnt get too high (not using THC as a crutch basically). They basically said "You're here for opioids and amphetamines. As long as its just weed and not benzos or meth or opioids then its not a huge deal. Just dont let the weed become an issue itself"
 
This question would be pretty much impossible to answer man. I understand we have been leaving drug testing threads open on a probationary basis, though this likely is going to get closed if we determine there is no way of answering your question. I will tell you that Mitragynine is not commonly tested for. I'm sure that with Kratom becoming as popular as it is, we will be seeing some kind of testing in the future, however, it does not seem to be the case right now.

I have no idea why Buprenorphine would be coming up. It looks like nobody really knows.

You could be right on the line regarding your Cannabis test. I know they can be quite sensitive when employers are involved. It's not unheard of for daily smokers to pop up up to 4 weeks after abstinence. Good luck, I hope it works out. I would ideally try to push the test back as far as possible. I consider the Cannabis to be your biggest problem here, not the Kratom, which is highly unlikely to be of any relevance.

I understand, I'm not on here much and tend to just lurk when I am anyway so I'm not all that familiar with the rules. Sorry about that.

I think I'm just going to take a break from kratom and order from a different vendor if/when I go back. I'm not thinking they'll be giving me the expanded opioid test, just wanted to be on the safe side if they do, but I think it would specify on the papers they sent me and those only say 5 panel.

I am concerned about the thc, but the test is pushed back to the day before my start date, so that's as far as I can get it as is. Gonna test myself again the day before that and then just drink tons of water, take some zinc the day of, and if it comes up positive I'll just mention my medical card in my previous state and sleep issues. At that point there's not much more I can do I suppose. Hopefully they were just checking for meth/heroin and don't care.

The restaurant where I work orders drug tests only if there's a work-related injury. But they specifically do not test for THC, even though it's still illegal in this state. They know that 95% of their work force uses cannabis and we are damn good workers!

Our manager has told us that even if we test positive for alcohol or another prohibited drug, that's not necessarily grounds for dismissal. It's just that the company won't pay medical bills or workman's comp if the employee was fucked up-- which is fair and reasonable.

It took 80 days for me to piss clean on weed.

Most employment, at least from what I have seen unless a federal position or position where dangerous machinery is used, has excluded cannabis in the test.

There is cannabis everywhere, even people that don't use may pee dirty from a previous gummy or other chance ingestion.

But the false bupe I have no answer for. But took me 11 days to pee clean from weed some years back after daily smoking. I have a fast metabolism.
 
I got to see what 7-OH does to someone with zero tolerance. The guy is familiar with Roxi somewhat but hasn't taken any this year.

He took 1qty Opia PI+7-OH 20mg tablet. He was itching like crazy and within 30mins he was nodding off and fell into a deep sleep.

Just wild how strong that stuff is. It showed me why people that do not handle opioids well should stay away from 7-OH and PI+7-OH.
