They don't have to wait at all. However, you could refuse repetitive tests which have occurred more than is really necessary as excessive or invading privacy.
Does it matter? You cannot test for it in drug tests.
No. Urine isn't drug tested for Rogaine.
Alcohol is looked at in most drug tests, especially drug tests such as the NCAA. However it will only show up within about 48 hours. So as long as you stay sober for 2 days before your drug test, you should be alright.
Depends on the drug in question, and what kind of test is being done. Hair tests can detect the use of some drugs for months. Urine tests are more commonly only good for days or weeks.
As with any perscritpion medication, when taken as directed it will not show up in a drug test. There is not enough opiod in them. Most drugs stay in your system and are detectable for 72 hrs up to 5 days depending on the amount. Pot stays in your system a mininum of 30 days upto 45.
Cotinine levels are obtained (as this is a major long half-life metabolite of nicotine).
Drug tests do not test for lidocaine or substances such as that.
Yes, the test will say what is in your system, as long as it is designed to test for the specific drug or drugs that may be in your system. No drug test detects everything, it tests for specific drugs.
No, but it gives an estimate. Drug tests test the presence of substances the body makes when processing the drugs. In blood or urine tests, most of these substances don't linger very long until they dissappear completely. In hair, since these grow slowly and don't deteriorate, drugs can be found much longer after use. Specific times differ from drug to drug, but it's never safe to say that they can't find any traces of the drug by tests or searches. In most countries, the legal basis for these tests is quite strict though, so you'll porbably never really encounter one.
It is synthetic meaning its fake! Therefore it doesn't get in your system and drug tests can't detect it!
The physiological effects are shorter than the length of time the drug will show up on any drug test. The physiological effets last hours to days. The drug will show up in drug tests for months.
Suboxone does not show up in drug tests. It only shows up if they specifically test for it, which my doctors say is highly unusual.
