Based on 1853 questionnaires derived from adolescent students participating in the 1995 Ontario Student Drug Use Survey, this article describes the prevalence of rave attendance and the drug-use profile of rave attendees and those participating in similar activities (i.e. bush parties). The results showed that 13% of the sample attended a rave during the 12 months before the survey. Although ra...

The recent growth of the network has also led to performance problems, as well as attempts by some governme...

This is the 1st study to evaluate this type of dual-process interaction in the prediction of drug use a...

Recommendations of the type “people who viewed this item also viewed this item” are powered by pairs of viewed items mined from Europeana. However, due to limited usage data only 10.3% of items in the PATHS dataset ...
