Abstract

PURPOSE:

Marginalized people are often absent from population surveys of substance use and from research based on care data. Special methods are needed to reach these small but very significant groups. This study analyses how patterns of intoxicant use have changed over time among one of the most marginalized group of people, the prisoners.

METHODS:

Nationally representative samples of Finnish prisoners were examined: 903 prisoners in 1985, 325 prisoners in 1992, and 410 prisoners in 2006. Comprehensive field studies consisting of interviews and a clinical medical examination were used.

RESULTS:

In 1985, a diagnosis for alcoholism was given to 41% of the men and 36% of the women prisoners. An increase over time was observed, and in 2006, 52% of men and 51% of women prisoners were alcohol dependent. Dependence on a drug was diagnosed in 6% of men and 3% of women in 1985; this prevalence had increased to 58% of men and 60% of women in 2006.

CONCLUSIONS:

A dramatic change in prevalence of illegal drug use and drug addiction among prisoners has taken place in the past 20 years. Recognizing this shift from alcohol to other intoxicants is important since drugs are illegal substances and thus tend to lead to involvement with the judicial sector, thus stigmatizing and deepening the spiral of marginalization.
