Use of doping agents probably involves more than a desire to enhance appearance or sports performance and appears to have much in common with use of alcohol, tobacco and psychotropic drugs.

The aim of this study was to determine the extent of doping drug use among adolescents in Uppsala, Sweden, and to analyse the main reasons for the use. An anonymous multiple-choice questionnaire was distributed among pupils in the first and the third grades at high school; 2,742 pupils participated in the study. The results showed that 2.7% of the male and 0.4% of the female adolescents had used doping drugs at some time in their life. However, knowledge of how to get doping drugs far exceeded use. The main reasons for using doping drugs were to improve appearance and to enhance performance in sports. Some boys self-reported side effects of AAS. Despite the still predominantly negative attitude toward doping prevention programs have to be taken.

In recent years a male group of anabolic-androgenic steroid misusers has been identified to share socio-demographic and personality related background factors with misusers of psychotropic substances, as well as being involved in habits of multiple drug use. The present study aimed to assess whether anabolic-androgenic steroids (AAS) would affect the density of the dopamine receptors in areas implicated in reward and behaviour in the male rat brain. The effects of 2 weeks of treatment with i.m. injections of nandrolone decanoate (15 mg/kg/day) on the expression of the D(1)-like and D(2)-like receptors were evaluated by autoradiography. Specific binding of D(1)-like receptors was significantly down regulated in the caudate putamen, the nucleus accumbens core and shell. D(2)-like receptor densities were down regulated in the nucleus accumbens shell, but up regulated in the caudate putamen, the nucleus accumbens core and the ventral tegmental area. These results are compatible with nandrolone induced neuroadaptive alterations in dopamine circuits associated with motor functions and behavioural paradigms known to be affected following AAS misuse.

The characteristics of AAS users extend beyond activities such as strength training and multiple drug use to include social, personality and health aspects.
