What is COCA?

COCA provides information, training and consultancy on drugs and alcohol

Drug workers who needed an arena for support and information around the issues of crack and cocaine founded COCA in 1996. Since that time COCA has grown into a national resource helping local authorities, services and workers develop appropriate interventions and professional working practices.

COCA was registered as a charity from 2001 to 2008. In 2019, COCA’s training arm was resurrected by two of its former directors, Tony D’Agostino (TD Consultancy) and Aidan Gray (Porchlight).


To provide evidence-based information, advice and support to organisations and individuals working with the issues relating to drug and alcohol use.
