To "thin" the herd when it comes to the job market, any job that offers year round employment with benefits, vacation and sick days, should do a hair drug test instead of urine. Addicts are getting smart and able to buy detox kits that flush all drugs out of their system for up to 48 hours, or they purchase clean urine so it looks like they don't do drugs. Hair goes back up to six months. It's not an invasion of privacy or violating any rights and the test costs roughly the same. Too much money is spent on sending employees with addiction problems to rehabs. Prevent it before it happens.
