Substance abuse is a huge, worldwide problem. In the United States alone there are over 50 million binge drinkers, 17 million illegal drug users and almost 15 million people who abuse prescription medications. Most substance abusers have jobs. In fact, it is estimated that one out of every ten workers has a substance abuse problem. An employee with an alcohol or drug problem can decrease productivity, create a hostile work environment and damage a company’s good name.
