At Massachusetts Mobile Drug Testing we realize that studies shows that more than 70 percent of substance abusers hold jobs; one worker in four, ages 18 to 34, used drugs in the past year; and one worker in three knows of drug sales in the workplace. In the workplace, the  problems of these substance abusers becomeyour problems. They increase absenteeism, create a higher risk of accidents, lower productivity, increase workmen compensation rates, and reduce profits. A comprehensive drug and alcohol-free workplace program may be the best means of preventing, detecting, and dealing with substance abusers at your workplace.
