Analyzing decision-making networks may give insight into the motivations behind poly-drug use. We correlated average functional connectivity of the valuation system (VS), executive control system (ECS) and valuation-control complex (VCC) in a large population sample (n = 992) with drug use behaviour. VS connectivity is correlated with sedative use, ECS connectivity is separately correlated with hallucinogens and opiates. Network connectivity is also correlated with drug use via two-way interactions with other substances including alcohol and tobacco. These preliminary findings can contribute to our understanding of the common combinations of substance co-use and associated neural patterns. © 2021 Elsevier B.V. and Japan Neuroscience Society publisher: Elsevier Ireland Ltd date: 2021 type: Article type: PeerReviewed identifier: Loganathan, K. and Lv, J. and Cropley, V. and Zalesky, A. and Ho, E.T.W.
