Verslawing is 'n breinversteuring wat gekenmerk word deur kompulsiewe betrokkenheid by lonende stimuli ondanks nadelige gevolge.[1][2][3][4][5][6] Ondanks die betrokkenheid van 'n aantal psigososiale faktore, 'n biologiese proses — een wat veroorsaak word deur herhaalde blootstelling aan 'n verslawende stimulus — is die kern patologie wat die ontwikkeling en instandhouding van 'n verslawing dryf, volgens die "breinsiekte-model" van verslawing.[1] Baie geleerdes wat verslawing bestudeer, voer egter aan dat die breinsiekte-model onvolledig en misleidend is.[7][8][9][10][11][12]
