Husband failed drug test-swears its wrong

[Whatwouldyoudo8988]

My husband has had a drug problem for a few years. About 3 years ago he did it in the house whilst the children were asleep and I was in the shower, he had overdosed, paramedic came out and the called SS as obviously there were children.
I threw him out
He went to doctors and got some medicine sorted for his depression and anxiety, and got completely off the drugs.
I had him back but the trust was broken so I order some drug test online which I did everyweek to know that he was staying away from them.
Hes been fine and relationship has gotten much better i haven't drug tested him this year.
Yesterday he seemed off so I asked if didnt mind doing a drug test he did it and it came back positive for drugs. He was shocked saying he hadn't touched anything, i check the date expiry on them and they are in date, i did one and it came out negative.
Hes lying isn't he?
What shall I do? He swears its wrong
How can I know the truth, I can't have that shit around my kids.
Do these tests ever come out wrong?
Please advise me

You ask him to leave.

How can this be your future? Testing every week / every time something is off. It's no way to live.

You already know the answer.

He’s on drugs around your children.

You know what to do.

What drugs are we talking about here? It could be anything from hard smack to an addiction to prescription painkillers.

Ask him to take another. False positives are possible, but rare. Another test ought to clear it up.

Stop trying to convince yourself that he isn't lying. He is lying straight to your face. Your husband is an addict, and addicts lie as much as they breathe.

Chuck his out right now. You have him a second chance and he's fucked it right up. Don't be daft enough to give him a third.

I am so sorry for you. It's impossible to build trust with them, as I know to my utter cost. I think you'd be better off forging a new life, but I know how hard that is. Testing someone every week is dysfunctional, but you know that. Good luck to you.

It’s hard to advise you if we don’t know if it’s a few spliffs or if he’s on smack!

I did 2 yesterday both showed positive for drugs

Sorry x post

The only thing I can think of that would account for it, is he on medication? So medications could fail a drugs test especially if they are an opiate based one.
Other than that, he is probably lying tbh. Maybe as you haven't tested him this week he thought he would get away with it. 🤷‍♀️

No one here can comment on the accuracy of the tests. This doesn’t sound like a trusting and respectful relationship.

He seemed off as well. Addicts tell me to never trust an addict. This is your red line, I'm sorry.

I knew it'd be coke. Leave.

hes been on anti histamine for a few months, and changed his medication to citlopram at the start of year.

If you hadn't had the tests, he was still already acting oddly and you would have been suspicious anyway. You suspect he has used and now you have confirmation. There are some medications that can result in a false positive for opiates. I've never heard of a false positive for cocaine.

What's the real issue here? Two positive drug tests means he's using again. Are you afraid to throw him out?

I think its fucked up to be putting your partner through drug tests.

If you don't trust him then dont be with him and move on.

Cocaine has a relatively short time period it will show up in a drugs test. 24 hours or something similar I think. How had he been acting in the day preceding you doing the tests? Coke makes you feel grumpy as hell after.

You can very ocasionally get false positives. It's vanishingly unlikely though, when in someone who's is known to use that drug... I would very, very strongly consider him to be lying.

It doesn't matter if these tests ever give a false positive. You know that.

The issue seems to be you have outsourced your decision-making to a test. I can understand why but it's kind of meaningless unless you stick to it.

It would be equally legitimate to go with your judgement that led you to insist on a test in the first place. That is enough to say - I can't do this anymore.

Also, what are the odds two tests will give false positives?

Lots of things, including some anti-histamines, can cause false positives. With some tests even yeast can cause them! So the answer is yes, despite what people here are telling you, these tests can and do come out wrong for lots of reasons. So nobody here can tell you that the test is accurate, and nobody can tell you he is using again. But since you can't trust him, that is a bigger issue. It might be put succinctly, but if your relationship is based on the results of a drug test, or being able to conduct a drug test, then drugs are not the main problem. I fully appreciate that living with an addict, especially when children are involved, is difficult. But you either have to trust what he says or there is no real basis for the relationship.

I wouldn't risk it and I'd leave.

Omg you have to drug test your husband? Wtf - that’s actually ridiculous. The trust is gone - I don’t think you have a future.

Never trust an addict. They lie. Ask him to leave for your own piece of mind.

If done in the same time period, or without excluding all of the possible triggers that are not "drugs" (as even ibuprofen can trigger false positives) then actually the odds of two tests being wrong are quite high!
