One thing is the novacaine the dentist shoots you with when taking out a tooth.
There is detailed infprmation on all the drugs it could be here http://passyourdrugtest.com/false-positives.htm
Well yes and no, i would assume you mean dangerous substances like talcum powder or glass or something like that but it is simply an urban myth that cocaine is mixed with substances like this after all its not in the dealers intentions to kill someone. But then cocaine its self is a dangerous substance and is often mixed with similar, cheaper analogue of cocaine. These could be research chemicals which can potentially be lethal.
The possessive form for the noun substance is substance's.Example: The substance's origin could not be determined.
you could but its not very smart:/ it may mess up the results unless you get it all out of your system b4 you take it:) hope i helped
You would see if a substance is a mixture or a pure substance because a mixture is where 2 or more things are mixed together. A pure substance is where it could be made up of different atoms, or it could be made up of one substance. Just like honey. A pure substance can't have different ingredients, only different atoms.
No. There is no evidence of this, scientifically. Besides, even if it could, which it can't, you would be trading one illegal substance for another, and you would still test positive.
some chemicals in cocaine are absorbed by the skin. so if you were to handle large amounts of cocaine it could result in a positive. also some of the very fine powders could float in the air and be breathed in and/or ingested. another consideration would be human tampering. could somebody have slipped it in your drink or food? maybe laced a cigarette or tobacco pipe? have you done any other drugs that could have been mixed with cocaine?
There is pretty much nothing that would cause a false positive for cocaine. Good luck.
No, endocet will show positive for opiates.
phentermine, the weight loss presciption
There are few things that can cause a positive cocaine test the most common is quinine so if you are partial to a gin and tonic this could cause a positive test.
Cocaine on a drug test can show positive due to:procainelidocainenovocaine...I hope you are starting to see a pattern.Some people have said that aspirin can also show up as a positive cocaine test.
Just wait and drink lots of water
Hmmm...the cocaine you used nine days before would do it.
Drinking coca tea could lead to a false-positive result for cocaine
Coming from an employee of a medical review office for drug screening.....NOTHING. When it goes through GC/MS confirmation testing it rules out false positives. False positive are a thing of the past (for lab based tests)
A mixed non-uropathogenic gram positive flora is a possible result for a urinalysis. This means the urine sample did not have any bacteria that could cause an infection.
