The Australian Drug Foundation have just released a new prevention factsheet, which covers the basics of drug prevention strategies. You can find it here: http://tinyurl.com/lmvwb5m
As stated in the factsheet, most of the content comes from this document by the Premier's Drug Prevention Council in Victoria - "Resource guide for planning effective community drug prevention." http://www.health.vic.gov.au/vdapc/archive/drug_prev_guide.pdf
This item was published in 2009, however the research used within is dated back to 2007.
