Drug testing at work

Drug tests are pointless, they can only test for a small minority of drugs with long half lives and only give positive or negative results which results in good employees not under the effect of drugs being fired which then results in reduced productivity and an increased cost to the business, as well as a bad reputation for the company and a reduction in the number of job applications because people don't want to work for a company where they will get fired. In addition to that, the high false positive rate means many people who have not taken drugs are fired. Widespread drugs testing results in a trend towards the production and use of shorter acting drugs in my observations, which are undetectable.

Even that doesn't list some medications that are prescribeable. :p

What part? Most of it is common knowledge and can be found on wikipedias drug testing article.

I've bolded the bits of your claim that need some sources. To me, your post was confusing. You claimed that "good employees" who "aren't under the effects of drugs" are going to get fired for failing drugs tests.

Seems odd to say the least.
 
Depends on what shows up and whether people could lose their jobs over innocent reasons.

E.g. I know a girl who had recently been drugged on a night out and she is so ashamed that she wont tell anyone except one of her mates. I only found out by chance as her friend is my other half.

Poor girl, she is stubborn enough to just take the rap and move on. (Poor or stupid anyway :()

Drugs have a half life longer than their duration of action, so even though a drug wears off within a few hours and the person is no longer under it's effect, it will still be present in their blood stream in small amounts and they will fail the test.

Food products that contain poppy seeds like bagels give false positives because poppy seeds contain very small amounts of morphine and codeine.

Also painkillers in pharmacies contain codeine and some decongestants contain l-methamphetamine, both of which will make you fail a test.
