The use of Ecstasy has received much attention in Norway during the la
st couple of years. However, there has been a lack of knowledge about
the users: how many are they? Are they in particular subculturally ori
ented and resourceful adolescents from the prosperous western parts of
Oslo, or has there been a diffusion to other segments of the youth po
pulation? In a representative sample of 11245 adolescents from Oslo, a
ge span 14-17 years, the 12-month prevalence of cannabis, Ecstasy, and
amphetamine use was investigated. Thirteen percent had used cannabis
last year, while the corresponding figure was 3% for Ecstasy and for a
mphetamines. There was an association between Ecstasy use and preferen
ce for house and techno music. More significant was, however, an assoc
iation between the use of all the three illegal drugs and between thes
e and the use of cigarettes and alcohol and alcohol problems. Mokken S
cale Analysis was used to investigate stage sequences and revealed tha
t Ecstasy was introduced after alcohol, cigarettes, cannabis and amhet
amines. Further, there were strong associations with behavioral proble
ms and moderate associations with internalizing mental-health problems
. There were small differences with regard to use of Ecstasy in the di
fferent areas of Oslo, but cannabis was more prevalent in the wealthie
r western parts of Oslo. In conclusion, ecstasy has become part of a w
ell-established pattern of illegal drug use in Norway.
