The extent of drug prevention and addiction workplace programs varies greatly from industry to industry. Industries with higher than average safety concerns - such as the airline industry and the medical industry - often have stringent drug prevention protocols, including random drug testing. There may be mandatory leave assigned to workers who test positive. Those who work with children are also subject to rigorous screening.
Other industries - such as entertainment, finance and contracting - tend not to emphasize corporate oversight when it comes to drug use. In these industries, afflicted individuals sometimes seek help when their problem starts to interfere with the quality of their work. When seeking treatment, they may have little support from their professional community.
