In a representative inquiry we found significant differences in the self-assessment of 4082 20-year-old Swiss men, as to whether their consumption of alcohol and drugs is high, low, or zero. The heavy users of alcohol and drugs describe themselves as men with frequent personal difficulties and psychosomatic disturbances. They tend to separate earlier from their family and prefer a less conventional, more consume-orientated, and passive way of life than the remainder.
