Lab tests can be much more accurate than a home test, but the best home tests are pretty much identical to the simpler lab screens.
One advantage the lab will have is better technique (due to practice) and familiarity with what a positive or negative test is supposed to look like.
They are said to be just as affective, but I believe that the most percise way and most accurate would be at the lab. In a nut-shell "home" drug tests suck but shouldn't be taken for granted.
No but they do have drug test that test for every harder drug then bud
If the drug test effectively tests for Benzodiazepines, then yes, it will. If it is a generic urine test purchased for home use, they usually do not test for Benzos. Home urine tests only test for THC, Cocaine, PCP, Methamphetamines, and Amphetamines.
The majority of drug tests only test for 5 drugs: marijuana, cocaine, pcp, methamphetamine, and opiates. So unless a drug tests is testing specifically for LSD,(which they typically do not) then LSD will not cause a positive.
Although cocaine itself only remains in the users blood for around 72 hours the drug test for cocaine is actually testing for its metabolite known as benzoylecgonine. Benzoylecgonine remains in the body for up to 30 days after cocaine has been last used which is why cocaine is listed as substance being tested for on standard 5 panel drug tests.
Coke "cocain"
One is done at home and the other is done in a lab. It really depends upon the lab! Some labs actually use the same tests that are often sold for home use. Sometimes labs will perform a "rapid test" and them only do GCMS or LCMS confirmations. For more information about labs or rapid tests, see drugs-information-home-page.com They have lots of information about drugs, drug testing, labs, home drug tests, etc.
Yes. Cocaine is only detectable in swab tests for a couple of days.
There are no home remedies for passing a cocaine test. The only thing you can do is eat properly, and drink plenty of liquids to pass thru your system. Cocaine basically comes out of your system in a few days so the wait is not terribly long too be clean from the drug.
cocaine
It can be. The simplest, most basic five-panel drug test--THC, cocaine, opiates, amphetamines and methamphetamines are the Department of Transportation's big five--only costs about four dollars in quantity. At the other end of the scale are "comprehensive" tests which look for every abusable prescription drug in the world. Those tests run hundreds of dollars.
They can take samples of your follicles and even give you a cotton swap test. Cocaine can be detected by a urine sample drug test. Interestingly, cocaine can only be detected for a few hours right after being used.
None..! Cocaine is a tropane alkaloid, only cocaine shows up as cocaine on a drug screening. The medications used for pain (opiates or the synthetic opioids) will show up as just that, opioids.. Most opiates show up as morphine metabolites. Standard drug tests for opiates also test for the metabolites of other commonly abused opiates (diacetylmorphine (heroin), oxycodone, hydromorphone, codeine metabolites, etc.)
Most drug tests are only testing for the 5 drugs that are part of a standard drug test (Marijuana,Cocaine,Opiates,Meth,PCP). Unless they have a reason to suspect you of using another drug, they will most likely leave it at testing for the drugs I listed above.
