WASHINGTON -- One in 12 full-time US workers acknowledges having used illegal drugs in the past month, the government reports.
The highest rates were among restaurant workers, 17.4 percent, and construction workers, 15.1 percent, according to a federal study. About 4 percent of teachers and social service workers reported using illegal drugs in the past month.
Federal officials said the survey is a snapshot and was not designed to show whether illicit drug usage in the workplace is growing or declining. The current usage rate is 8.2 percent. Government surveys reflected a usage rate of 7.6 percent in 1994 and 7.7 percent in 1997, but those studies involved a much smaller sample.
