Most people will agree that substance abuse, the nonmedical use of drugs (especially alcohol), is today a worldwide problem. We have only to read a newspaper or news magazine; listen to the radio or televi­ sion; attend a school conference or PTA meeting; listen to law enforce­ ment, health, and school officials; or just talk to our children to grasp

the magnitude of the problem. Yet, with millions of dollars already spent and currently being expended, countless hours of education and train­ ing, and warehouses of literature produced, the substance abuse prob­ lem continues to grow — reaching into almost every area of daily life and leaving virtually no one untouched, regardless of age, socioeco­ nomic condition, or occupation. This is particularly true in the work­ place.
