Abstract Objective The aim of this study was to evaluate the vestibular system in substance addicts. Methods A total of 34 substance addicts were included in the study. A demographic data form, the Dizziness Handicap Inventory, the Addiction Profile Index Screening – Short Form, the Video Head Impulse Test, videonystagmography, and cervical and ocular vestibular evoked myogenic potentials tests were administered in all participants. Results A statistically significant difference was found between the study group and the control group ( p < 0.05) in terms of gaze, saccade, pursuit and optokinetic results in the videonystagmography test; lateral, anterior and posterior semicircular canal gain values in the Video Head Impulse Test; P1 latency, P1–N1 interlatency, P1–N1 amplitude and asymmetry values in the cervical vestibular evoked myogenic potentials test; and N1–P1 interlatency, N1–P1 amplitude and asymmetry values in the ocular vestibular evoked myogenic potentials test ( p < 0.05). Conclusion As a result of our study, it was observed that the vestibular system was affected in substance addicts.
