GCS Survey: "GHB IN CHEMICAL SUBMISSION: MYTH OR REALITY?"
France200 participantsStarted 2024-03-20
Plain-language summary
According to the media, GHB is the main substance used for chemical submission. The national survey conducted by the Addictovigilance centre of Paris on drug-facilitated assaults shows that GHB is used, but only in a very small proportion of cases. However, the short detection times for this substance point to its possible under-detection (06-09h in blood, 10-12h in urine). A pilot research protocol in Ile de France focusing on capillary analysis is therefore being proposed to volunteer victims to overcome this bias and answer this question: is the massive use of GHB in chemical submission a myth or a reality?

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

What they're measuring
1
Evidence of exogenous GHB intake without the knowledge of the victims through hair analysis.
Timeframe: Samples taken between 2 and 6 months after the presumed events: GHB analysis in the hair can no longer be interpreted after 6 months due to the hydrosoluble nature of GHB and repetitive hair washing.
