Drugs change a person’s reaction time, personality, and ability to concentrate. Because of this, it’s no surprise that few employers want to deal with workers who abuse such illegal substances. For the most part, large businesses have policies to cover drug screening employees.
Smaller businesses, however, are more likely to unknowing hire drug users. Because many of these businesses do not require pre-employment drug screening, substance abusers are more likely to apply for positions. According to U.S. Department of Labor statistics 44 percent of illegal drug users work for companies that have less than 25 employees. Another 43 percent work for medium sized businesses, places that employee between 25 to 499 individuals. Only 13 percent of the country’s illegal drug users are able to seek past the drug screening efforts of larger employers.
