What this trial studies

This observational study aims to investigate the prevalence of gamma hydroxybutyrate (GHB) in cases of chemical submission, particularly in drug-facilitated sexual assaults. Conducted by the Addictovigilance center of Paris, the study will utilize capillary analysis to gather data from victims who exhibit clinical signs suggestive of chemical submission. The research seeks to address the limitations of previous surveys and provide a clearer understanding of GHB's role in these incidents. By analyzing historical data and current cases, the study aims to determine whether the perception of GHB as a prevalent 'rape drug' is a myth or a reality.

Who should consider this trial

Good fit: Ideal candidates for this study are French-speaking adults over 18 who have experienced suspected chemical submission with relevant clinical signs.

Not a fit: Patients who are minors, recreational users of GHB, or those with no evidence of a crime may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved detection and understanding of drug-facilitated assaults, enhancing victim support and prevention strategies.

How similar studies have performed: While previous studies have reported low incidences of GHB in chemical submissions, this approach using capillary analysis is novel and aims to address under-detection issues.
