Klonopin and a U.A.

[bill1234]

Quick question... will klonopin make me fail a U.A.?

[corlene]

if they test for benzos yes

[bill1234]

Thanks for the reply.

[Papa Verine]

You will test positive for benzodiazepines. If you are not prescribed benzodiazepines you will have some explaining to do.

Guess i'll just borrow some clean piss... No telling what else would show up anyway

I know this is gonna sound strange to all. I take Xanax perscribed by a doctor so when I take UA's at the methadone clinic I get all kinds of shit if I dont come up positive for benzo's because thenm they know I have taken them too fast. Anyway I had a test the next day and knew I would test negative on benzo's so took 10mg of clonzepam (Klonopin) and still tested negative the next day.

Other people at my clinic started to think they would test negative like I did, but all came up positve. By no means chance it, but it is reallly strange that i took the clonzepam and still was negative and may be worth some investigation to whether this happen for anyone else, by the way I know they were clonzepam, they were my Mom's.

[OxyContinuously]

sure, a standard "NIDA 5" test tests for :

1)THC

2) amphetamines (meth and stuff like adderall, etc. dexedrine)

3) morphine and heroin (they test for morphine metabolites and for MAM- a metabolite specific to ONLY heroin use, no other opiate...historically, the semi synthetics and full synthetics, also thebaine derivatives were not tested for, but remember after the OxyContin propaganda brought on by that fat piece of american shit, Rush Limbaugh, many testers use an "extended" version, which tests for morphine and heroin, but it now can include hydrocodone, oxycodone, and fentanyl; meperidine to a lesser degree, but remember chances are you will only get the extended test if you are suspect to begin with, u get me?)

4) cocaine (specifically the metabolite benzoylecgonine)

5) PCP (phencyclidine and it'll catch related cyclo-hexanones such as ketamine for example)

Notes:

You can see that in the standard 5 panel test (the most common one given these days, benzodiazepines are not specifically tested for...They are part of an extended panel which includes them AND also the extended opiate list I highlighted above, along w/ the barbiturates...

Your bottom line:

---> Okay, honestly at the company I work at (a laboratory in CT; I'm a chemist) our pre-employment screening included the basic "NIDA 5" and ALSO oxycodone, hydrocodone, and benzodiazepines.

---> the addition of oxycodone, hydro, and benzos seems to pretty standard throughout, in most reputable places that bother to give a screening...

---> Yes, Klonopin (clonazepam) will show up b/c it has a very long half life, on the order of 35 hours, give or take 5 hrs depending on weight, personal sensitivity and metabolism...A safe waiting period to guarantee negative results from Klonopin would be to wait 72 hours, if possible.

---> Urine is one thing, but depending on the place, some also do a hair screening. THis can be tricky. Benzodiazepines can last up to 42 days in human hair from a single exposure, cocaine and opiates can last up to 6 months depending on regularity of usage, the minumum from one exposure being about a month, give or take. Amphetamines (detection level being as miniscule as 25 nanograms) can last for months as well, but if u are a real "tweaker," chances are you're not fit for employment anyway, u know ;-) so the test is moot!

---> PCP and aryl- and non aryl- cyclohexanone-type dissociatives can last for about a month in hair. Same applies to dextromethorphan...

---> Try to stay away from dextromethorphan for at lest three days before your test. Why? Because DXM can do some crazy things to your results. You can test positive for PCP, or more commonly you will receive a "false-positive" for opiates. THis is because dextromethorphan is a stereoisomer of an opiate compound called levomethorphan, a Schedule II narcotic medication. (isomers share the exact same amounts of the exact same atoms, however they are different compounds due to how such atoms are arranged on the parent rings; think of isomer as a mirror opposite)

---> if you are prescribed Adderall, Metadate, Ritalin, Concerta, Focalin, Dexedrine, or any pharmaceutical compound containing: amphetamine, dextro-amphetamine, methylphenidate, or dex-methylphenidate, please tell your tester, b/c all these meds will give u a false positive for amphetamines/meth.

---> Allergy medications containing both phenylephrine and pseudo ephedrine can also give a false positive for amphetamine, although the level is usually much lower than that detected by the test.

[Reason being is b/c pseudoephedrine hydrogenated on the hydroxyl group, and/or the reduction of ephedrine in the presence of red phosphorus and hydriotic acid; with sodium hydroxide added later to basify the mixture and raise the pH to around 12-14 yields methamphetamine as fine, clear, glass grade shit...sorry about that, i just wanted to give u the full picture, so u could understand why things like "Sudafed" would even remotely have u test positive for something like meth!!]


So bro, I know that was quite long-winded, and if I rambled, I am indeed sorry, but I wanted to cover anything and EVERYTHING...Drug tests are important; if not planned properly, one can ruin their reputation, lose ap otentially great job, or worse, you know?

Hopefully you are prepared with everything you could possibly need to know about drug testing, and the nmethodology and science behind it.

Good luck and feel free to PM me if you have any more concerns.

take care

I'm actually curious about this... alprazolam and clonazepam and other benzos don't all metabolize to the same things, so do they have to test for a bunch of different metabolites for the most common benzos?

[GA_M'Done120]

I don't know why, but I take klonopin daily and it has not showed on my ua's. I was told the cheap,basic Ua's my clinic uses; klonopin does not show up because it is not considered a "street" drug. I was also told the same goes for ativan, and a couple other benzos don't show up for the same reason. Xanax and valium show up because they are considered a "street drug". I know that sounds crazy, but that was the reason I was given.:confused-

[GA_M'Done120]

The clinic I attend does check for benzos because even if you have a legal script you cannot have takehomes. I take klonopin every day and have never tested positive for benzos. maybe it is just a fluke, but if it is a fluke it has been a 10 year fluke. I really respect your info OxyContinually, but I have never tested positive for benzos because if I test positive I would lose takehomes.

[Black_Pony]

I've had a full laboratory benzodiazepine panel run on me before and they tested for A GREAT MANY metabolites. The only one I can remember off the top of my head was oxazepam because I was using mostly valium at that time and that was one of the metabolites I had a high concentration of. They also test for the five main benzos in unmetabolized form as well.

My UA was taken more than 3 weeks from my last dose so all I had was metabolites, but I still had them in high concentrations. That shit stays in your system longer than I had imagined.

Like mentioned above, alot of cheaper take home tests dont even test for benzos. Most people are looking for more insidious drugs like opiates. God forbid.

I'm actually curious about this... alprazolam and clonazepam and other benzos don't all metabolize to the same things, so do they have to test for a bunch of different metabolites for the most common benzos?
