摘要：Purposes: to investigate the quality of life and voice in addition to the main auditory perception changes and acoustic measures jitter, shimmer and Glottal Noise Excitation in users of licit and illicit psychoactive substances that sought a treatment center for chemical dependency. Methods: crosssectional study in which participants responded to questionnaires Voice-Related Quality of Life survey and World Health Organization Quality of Life Instrument-Bref. We made a voice recording of the vowel / a / and a count from 1 to 20. The vocal recordings were evaluated by GRBAS-I (G – overall degree of dysphonia, R – roughness, B – breathiness, A – asteny, S – strain) scale and acoustic analysis software by VoxMetria. Results: 29 protocols and voice recordings, 19 (65.5%) of the sample were male, and the mean age of the sample evaluated was 37.8 years-old. The scores both questionnaires indicate no differences between users of licit or illicit drugs. In perceptual analysis through GRBAS-I they revealed the predominance of mild and moderate changes in grade items of dysphonia, roughness and overall instability for licit and illicit drugs. The jitter and shimmer were altered for men and women, and most of the sample showed the standard deviation of the fundamental frequency as amended. Conclusion: changes in quality of life and voice were identified in both users of licit or illicit drugs. Most users showed changes in jitter and shimmer. Illicit drug users were more changes Glottal Noise Excitation standard deviation of the fundamental frequency.
