There’s nothing like an ice cold beer at the end of the day on a Friday; you’re so worn out from the week that the only thing to comfort you is booze. While this is pretty standard among any hard workers — whether they’re waitresses or investment bankers, third grade teachers or musicians — it turns out certain industries harbor more heavy drinkers and drug abusers than others.

It isn’t surprising, for example, that bartenders and waiters at restaurants are going to be more likely to be party animals — their night shifts call for late nights and even later mornings with a hangover. And perhaps it’s a comfort to know that workers in education have lower rates of drinking and drug abuse than other industries.

A new survey released by the Substance Abuse and Mental Health Services Administration (SAMHSA) combed through data from 2008 to 2012 to find that 8.7 percent of full-time workers aged 18 to 64 consumed alcohol heavily in the past month, while 9.5 percent were dependent on alcohol or drugs in the past year. The highest rates of heavy alcohol use were found mainly in the mining (17.5 percent) and construction (16.5 percent) industries, followed by the restaurant and hospitality industry. Hotels and restaurants, however, got first place for illicit drug use; a floor manager on coke is a familiar sight in fine and casual dining. Other runners-up for drug use include the arts and entertainment industry and management.

The survey doesn’t mean, however, that it’s the very nature of these jobs that are directly linked to increased drinking or drug habits. Instead, it’s very possible that the distribution of heavy drinkers in certain industries has more to do with their age and gender. For example, young, white males are more likely to drink than other groups — and they’re more likely to work certain jobs like mining or construction than others.

Other studies, however, have suggested that the motto “work hard, play hard” may ring true in competitive industries. One recent study found that people who worked more than 48 hours a week were more likely to drink heavily and develop alcoholism.

The authors of the latest report argue that lost productivity from alcohol and drug abuse is costly both for the individual and the economy. The Centers for Disease Control & Prevention (CDC) notes that excessive drinking in the U.S. cost $223.5 billion in 2006, largely due to lost workplace productivity, which accounted for 72 percent of the total amount. Other things involved health care costs, criminal justice expenses, car crashes, and property damage. The CDC adds that total state costs for binge drinking were, overall, almost the same as the costs for smoking and Medicaid.

“Employee heavy alcohol use, use of illicit drugs, and substance use disorder are associated with negative work behaviors such as absenteeism and frequent job changes,” the authors of the survey write. “This report indicates that the prevalence of substance use and substance use disorders is not consistent across industries.”
