King's College London

The Cocaine Cue Database (CCD) study will investigate how current users of crack and powder cocaine perceive cocaine-related images. We will measure the degree of craving experienced when viewing the images, which will help us develop an image database to be used in future studies to better understand the mechanisms and potential treatments of cocaine addiction.

Participants will be asked to complete one session online or face-to-face, with an optional second session – each lasting around 30 minutes. The results will be used to select images for the final database.

In addition to being used in future studies at King’s College London, the database will be made available to researchers worldwide to improve consistency and quality of research in the field of cocaine addiction.

Participants will receive £10 compensation for each session completed in the form of a Sainsbury’s voucher.
