Three providers have been confirmed to deliver preventative alcohol and drug education in South Australian schools through a $2.9 million State Government funding package over three years.

The funding will be used by Encounter Youth, Life Education SA and The Sammy D Foundation to provide evidence based, health living and substance abuse prevention programs.

This represents a new investment of $2.2 million, with $705,000 for the Sammy D Foundation having been granted in February 2018.

Schools can choose to use any drug education program to complement their curriculum, and non-government schools are also able to access the funded programs.

High schools will also be able to access the SAPOL-delivered comprehensive alcohol and drug prevention sessions.
