Abstract
A quantitative epidemiological prevalence study of problem drug abuse in Sweden is the basis for a study of differences between drug abuse among men and women. A significant difference between genders was that, of those who come to the attention of the authorities, fewer women than men abuse drugs. The women were younger than the men. A greater percent of women abused amphetamines and injected heroin, as well as abusing tranquilizers/soporifics. A larger proportion of women than men were unemployed. The men had a significantly longer history of drug abuse than the women, a greater percent of them were born outside Sweden, and more of them had smoked heroin and used cannabis. A greater percent of the men had used illegal means to finance their abuse. There was a group of women (17%, median age 32) at the margins of the society, i.e. who had no work or place of residence, socialized solely with other addicts and financed their habit by illegal activities. Abuse of amphetamines and heroin was the most common. The majority of the women were polydrug abusers. Sweden has historically had, and continues to have, a large number of amphetamine abusers, but has now also developed a distinct population of heroin addicts.
