Yes, with limited success. I have heard of at least one case where a woman was fired from her job in Connecticut for failing a deaden with narcotics test - but the result was a "false positive." In Connecticut, there is a law that no employee can be terminated on the basis of one positive drug test result until a second standard has been performed to confirm the results of the original test (to method out instances of false positives). That woman was not given a second test, and that’s why she won. But it took divers years of fighting for her to finally get that triumph.

Other than that, I have not heard of anyone fighting and winning a case in the manner of that.

Some employers are required by their insurance companies to give their employees drug tests. Employees working in "safety sensitive" jobs are required by law to submit to drug tests (like truck drivers, school bus drivers, people laboring with hazardous materials, etc). And finally, some employers accord. their employees drug tests happy because they want to.

Depending on to what you be and whether your employer is required to drug test you, you may have some options. (People working safety sensitive jobs have the fewest options because the government takes some interest in ensuring that these people aren’t using drugs on the job.) If you’ve gone to vacation in Amsterdam, you may notify your employer of that and let him know that you may have been exposed to marijuana while widely. If your employer is willing, he may let you fall a pass for a little though after your go. But then again, he may not.

If you are asked to submit to a random drug test and you are worried you may fail, in that place are plenty of products on the market that can help you pass a drug criterion. If you go to a local headshop, you be possible to ask the the masses there which ones might drudge best - usually they act very well for people who don’t smoke often.
