VR world may help cocaine addicts overcome cravings

Researchers are building a virtual reality world to help cocaine addicts overcome their cravings for the drug by repeatedly exposing them to tempting scenarios in a safe environment.

The project draws on the experiences of drug users to create tailored 3D experiences, such as being alone in a flat or at a party with friends, where people can be immersed via a VR headset in realistic situations that trigger the urge to take drugs.

Studies have shown that “cue exposure treatment” can substantially reduce cravings and relapse in recovering alcoholics, but the approach has not been fully tested as a potential treatment for cocaine addiction.

Lead researcher Paolo Deluca, a professor of addiction research at King's College London, said the VR world should help users break the association between tempting scenarios and their cocaine use, and give them time to practise strategies for refusing drugs.

“We are trying to better understand the scenarios, the cues and interactions, that trigger cravings in people who use cocaine,” he said. The work is one of 11 projects announced today as part of a £12m government investment to reduce drug overdoses through virtual reality, artificial intelligence and wearable technology.
