Drug abuse of Finnish male prisoners in 1995.

The purpose of the present research was to estimate the extent and variety of abuse of illegal drugs, use and misuse of hypnotics and sedatives and anabolic steroids in the Finnish prison population. The study was undertaken during October-November 1995 at four prisons, three of which were closed institutions and one an open prison; one of the three closed institutions was a juvenile prison. There was a total of 707 inmates in the prisons selected for the study. Questionnaires were given personally to all prisoners in the open prison and in the young prisoners' division in the juvenile prison, but in two large central prisons only some divisions were selected for the study. The questionnaires were completed by 354 prisoners; 75 prisoners refused to respond. A total of 27.7% of subjects reported taking illegal drugs while in their current prison and 70.1% had sometimes used them. Of those who were drug-free before their first imprisonment, 21.7% began using drugs in prison. At present hypnotics and sedatives were reported as in use by 41.8% of subjects, one-third as prescribed drugs and about 10% illicitly. A total of 3.7% of subjects reported taking anabolic steroids in the current prison. Cannabis and amphetamine were the most common illegal drugs reported. Intravenous drug use was reported by 19.2% of the respondents at some point in their lives, and 10.7% of prisoners had injected drugs in their current prison. Use of illegal drugs and misuse of drugs were significantly higher among young prisoners (< or = 25 years of age).
