In 2004, the Beckley Foundation reported on the legal changes that took place in Portugal in 2001, which effectively decriminalised the possession and use of all drugs, and diverted those arrested into education or treatment programmes (Allen, Trace, & Klein, 2004). This report aims to provide an updated overview of the effects of these changes, using data from the evaluations that have been carried out and from new interviews with key stakeholders in Portugal.
