Is there a home drug test to test for diphenhydramine o.t.c. abuse? I suspect my husband is abusing it
There's info here: https://en. Wikipedia. Org/wiki/Diphenhydramine
But, I'm concerned too about your relationship. Suspicion is often as harmful as the behavior in question. Consider Couple's Therapy after a few prep sessions for you alone to learn how to communicate concern w/o blame. A test would do nothing to help resolve any problem. Best wishes 2U2. ...Read more
I took two 50mg tablets of Diphenhydramine 17 hours before I had to take a pre-employment oral drug test. Is there a chance I might fail the drug test?
Unlikely: This would not be screened or confused with illegal drugs. However people often get drowsy from this relatively high dose. If you were to fail the test, it would be based on your performance and not the drug itself. ...Read more
I took drug test today and it was positive for tca, I regularly take an OTC sleep aid with diphenhydramine. Couldn't have caused the false positive?
"tca"????: Did you mean THC (marijuana or cannabis)? TCA medically usually means tricyclic antidepressant, and these are actually chemically similar to benadryl (diphenhydramine). If all that was done was a SCREENING test, there are lots of potential false positives, and if used for legal purposes, all screening tests should be confirmed with a more sophisticated test, usually gas chromatography/mass spectroscopy. ...Read more
It depends,,: It depends on what you're being tested for and how much benedryl you took. Apparently it may cause a false positive result for Methadone in some urine drug screens using competitive binding immunoassays, and if too much is taken, it can cause blurry vision, photophobia, heart failure, and death, but a lot has to be taken. Otherwise, there should not be much of a problem. Good luck. ...Read more
I took a drug test yesterday, and even though I don't use illegal drugs, I am fretting. I took one benedryl the night before. Is that ok?
It will not...: Attempting to foil a drug screen will just add misery for you--your employer or whoever is requesting the drug screen will see you not just a dope but also a liar (trying to hide/sabotage your drug test). So, it is better to come clean. If you have a problem, ask for help and you will get more respect that way. Be good. Be sober. Be drug-free. Be respected. Good luck. ...Read more
Yes: It can rarely cause a false positive pcp test. ...Read more

Does mixing two types of urine affect a drug test? My son haven't smoked in 3 months but he wasn't sure so he used his friends urine...When he put the urine in the test cup it wasn't enough. So he used some of his own....If he is clean and no marijuana come
Your son has a: Bigger problem, and if you are aware of this and not talking to him about personal honesty and dishonesty, and the difference, you are enabling him in making bad choices. Depending on what the urine test is for, if he is found out (there are a number of tests done on urine that can detect adulteration or someone elses pee) there can be serious legal consequences beyond not getting a job. ...Read more
Yes, depending on: When testing is done relative to when it was taken. However, "drug screens" are read as positive by the concentration of a drug or its metabolite in the urine sample; therefore, depending on timing, the concentration may fall below the cut-off point for a "positive" screen. It isn't a problem for anyone who can show a prescription bottle in his or her name. Diversion is a different story. ...Read more
Possibly: "false positive testing" occurs when a test finds evidence of illegal drug use when no drugs were taken. This can be a result of some over-the counter medications having chemical structures similar to illegal drugs. Pseudofed, found in many allergy and "cold" medications is one of these drugs. ...Read more
Be prepared...: Based on the sophistication of the test, or lack of it, quite possibly. ...Read more
I'm in Lamictol for seizures. Would this affect a drug test? & I have smoke pot for several yrs (small amnts) haven't smoked in 2 weeks, would it show?
Cannabis: Would show up on a screen for drugs of abuse but not on most standard tests. Single use of marijuana should be out of your urine in 1 to 7 days. Regular use of marijuana – should be out of urine in 7 to 100 days. Single use marijuana can be detected 12 to 24 hours in blood. Regular use marijuana can be detected for 2 to 7 days in blood. Marijuana regular use detected in hair for months. Single _ ...Read more
It should not: Even if one of these produces an interference by one method, thc assays must be confirmed by another test using a different chemical principle if they are to have any consequences to the person. This isn't the place to talk about the wisdom of the marijuana laws or testing which may have adverse consequences. Good luck and I hope things work out for you. ...Read more

Smoking a blunt after being clean for years Addiction won't be a problem, how many days will it take for a drug test to come up clean after doing so?
If by blunt you mean marijuana, a single joint used only once should clear out in a week or so. If you are near other people smoking week your test could be positive even if you did not smoke it. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco or alcohol in any form.

I'm 6'3 and 215 pounds. Smoked marijuana everyday for 7 months. I haven't smoked now for about a month. Should it be out of my system for a drug test?
I had back pain so bad today I couldn't stand. I took 1 10mg (my dads)cyclobenzaprine tablet Will this cause me to fail a military drug test in 10 days?

Half life is about 18 hours (up to 37 hrs) so by 10 days, you should be through 7-13 half lives so the amount in your blood should be negligible. So would not worry. Do not take any more unless you have a prescription (if you have a valid prescription, then it usually does not cause problems with drug testing). f/u/ w/ doc. ...Read more
I stopped smoking weed 17 days ago and took a home drug test and it came up neg my baby won't be born till Nov 11 will weed still be in my baby's syst?
Dr decreased my percocet from 120 month to 30 and I haven't passed all drug test and it's a chronic back problems. Are they allowed to do this and why?
Several reasons: First of all narcotics like percocet are best used for acute pain, not chronic pain. If not passing your drug test means that the doctor saw illegal substances in your drug screen then that is probably the reason for lowering your percocet. Narcotics mixed with street drugs are very dangerous and can result in death. Doctors can decrease doses if they feel it is necessary or dangerous for you. ...Read more
I've smoked marijuana once three days ago and had a mandatory drug test today at work. And before that haven't smoked in over 2 years. Is it in my sys?

If someone smokes marijuana around me (for just about 1 hour or whatever) will it still get in my system if I don't smoke it? I have drug test coming up
If breathing, maybe: If you're breathing and the person is smoking in the room with you, you could conceivably breathe in the marijuana and show up positive on your drug test. This would be secondhand smoke, and your levels would be less than if you were purposefully inhaling the drug. . . But to be on the safe side, i'd suggest steering clear. Why tempt yourself, or expose yourself to carcinogens in smoke anyway? ...Read more

What to do if I took a drug test for employment and didn't tell them the medications I take. And?
You could lose job: When you sign the usual form before giving a pre-employment drug test (or when you are already hired if random or for-cause testing is done), you are stating, often under penalties of perjury, that it is accurate. If you are positive for a potential drug of abuse and didn't tell them about it, they can consider it a positive test and act on it. Talk to the HR person involved and give them info. ...Read more
Hi I have hair drug test coming up and I haven't smoked for a 107 days and I weight around 315 can I pass it?
Probably: A standard hair follicle screen covers a a period of approximately 90 days. Metabolites from drugs Cocaine, Marijuana, Opiates Codeine, Morphine, Methamphetamine, Ectasy, PCP etc can be tested from the hair follicle. A lock of hair 1.5 inches or 3.9 cm is snipped from the head. Note substances can be detected from body hair (grows slower) for up to a year. Good luck. ...Read more

I was just told my daughters drug test didn't show pure heroin but heroin "metabolites" and I don't understand what that means?
Heroin metabolites: Hey wake up - this means that she has used heroin. Metabolites only show up after metabolism in the liver so she has used Heroin - get her some help before she dies from using heroin. ...Read more

I went to a friends garage party 4 days ago, people were smoking I was walking in and out of the garage. Can I fail a drug test? If I didn't smoke?
Marijuana?: It is unlikely that a urine drug test will be positive (or stay positive long) based only on this small second-hand exposure, however, depending on weight and how often you have smoked marijuana in the past, it may still be positive from prior use. If you are obese and/or a chronic, heavy user, a drug test will stay positive for several weeks-months. ...Read more

I recently had to take a drug test I used someone else urinr but I haven't smoked in 3 months but I was paranoid...I also took two drugs test which ca?
Not that I know of: Unless they are testing for caffeine, which would rarely, if ever, be done. However, the label says that the ingredients are "proprietary" which means they don't have to tell you everything that is in it. However, I have never seen any reports of false positives secondary to any kind of tea. In any case, false positives on screening tests can be ruled out with confirmatory tests. ...Read more
