CONCLUSIONS: Perceived devaluation was extremely prevalent among street-involved youth in our sample. We also observed that youth most in need of health and social services were significantly more likely to report high levels of perceived devaluation which may result in a reluctance to seek out key services and supports. These findings highlight the need to implement stigma reduction interventions for vulnerable youth in this setting. PMID: 30526206 [PubMed - as supplied by publisher]
Conclusion/importance: This work is significant in expanding the populations thought to be impacted by and understanding social disparities related to SC use. Further investigation is needed to assess the relationship between concomitant use of SC and other drug, particularly opiates. This may suggest that the sequelae of one drug may enhance or alleviate the effects of the other. PMID: 30526203 [PubMed - as supplied by publisher]
