Background: Complications related to Chemsex practice (consumption of psychoactive substances in sexual context) were first assessed by the French Addictovigilance Network in 2014. In response to the deaths reported in 2016, a new expert report was commissioned to update the complications and evolution of Chemsex‐related practices in France. Methods: Between January 2008 and August 2017, all Chemsex cases collected through the French Addictovigilance Network's epidemiological tools were analyzed. Comparison of data between two periods (before and after 2014) was performed to assess the evolution of practices. Results: Over the entire survey period, 235 Chemsex cases were identified, all of them in men, with a mean ± SD age of 39 ± 11 years, including 24 deaths (10.2%). An increase in the number of reported cases was observed from one in 2008 to 50 in the first 8 months of 2017. The main medical histories include human immunodeficiency virus (HIV; 45%) and hepatitis C (20%) infections, and substance use disorders (36%). In those 235 cases, 345 psychoactive substances were identified, mainly cathinones. Polydrug use was reported in 75% of cases. The main complications were substance use disorders (63%), acute neurological or cardiovascular intoxications (50%), various psychiatric disorders (39%), and viral and bacterial infections (18%). γ‐Butyrolactone (GBL) was present in 95% of comas. An increase in the number of deaths was observed during the survey period. Conclusion: The French Addictovigilance Network, via this pharmacoepidemiological surveillance, warns public health authorities in order to support harm reduction programs and the management of Chemsexers.

Introduction: Analgesics are among the most widely used drugs worldwide. This study describes the population treated with narcotic analgesics, their therapeutic indications and how the data have evolved over a decade. Methods: A cross-sectional, national, multicentre survey study was conducted that included surveys taken every year from 2007 to 2019 in a national sample of 1500 randomly selected dispensing pharmacies. Results: The mean age of patients, mostly women (around 60%), remained stable over the study period (63.2 ± 17.1 years in 2007, 68.2 ± 17.2 years in 2019). The proportion of patients treated for more than 3 months increased from 2007 to 2019. Most prescriptions involved morphine, oxycodone and fentanyl (98.5% of all prescriptions in 2019). Morphine prescriptions dropped dramatically from 49.6% (2007) to 32.3% (2019) of the total narcotic analgesics. Fentanyl prescriptions varied from 40.1% in 2007 to 32.2% in 2019. Prescriptions of oxycodone, regardless of the indication, increased steadily from 2007, from 8.3 to 34% in 2019, becoming the most prescribed narcotic analgesic for the first time since the beginning of the survey. Conclusions: This study demonstrates how narcotic opioids are prescribed, thanks to the active participation of health professionals, and confirms the striking increase in the prescription of oxycodone.

Background: In many countries, nitrous oxide is used in a gas mixture (EMONO) for short-term analgesia. Cases of addiction, with significant misuse, have been reported in hospitalized patients. Patients suffering from sickle cell disease (SCD) could represent a high-risk population for substance use disorder (SUD) due to their significant pain crisis and repeated use of EMONO. The objective of the PHEDRE study was to assess the prevalence of SUD for EMONO in French SCD patients., Results: A total of 993 patients were included. Among 339 EMONO consumers, only 38 (11%) had a SUD, with very few criteria, corresponding mainly to a mild SUD due to a use higher than expected (in quantity or duration) and relational tensions with the care teams. Almost all patients (99.7%) were looking for an analgesic effect, but 68% of patients were also looking for other effects. The independent risks factors associated with at least one SUD criterion were: the feeling of effects different from the expected therapeutic effects of EMONO, at least one hospitalization for vaso occlusive crisis in the past 12 months and the presence of a SUD for at least one other analgesic drug., Conclusions: The use of EMONO was not problematic for the majority of patients. Manifestations of SUD that led to tensions with healthcare teams should alert and lead to an evaluation, to distinguish a true addiction from a pseudoaddiction which may be linked to an insufficient analgesic treatment related to an underestimation of pain in SCD patients., Trial Registration: Clinical Trials, NCT02580565.

Background: Sickle cell disease (SCD) induces chronic haemolytic anaemia and intermittent vaso-occlusion that results in tissue ischaemia causing acute, severe pain episodes that can lead to frequent hospitalizations. These consequences can have repercussions on family, social, school and/or professional life. Here, we present some of the results of the PHEDRE study (Pharmacodépendance Et DREpanocytose-drug dependence and sickle-cell disease), which is the largest study of patients with SCD in France. This paper intends to describe characteristics of the French SCD population. We also aimed to assess the impact of the disease on the lives of patients using objective and subjective variables., Methods: The PHEDRE study was a national multicentric observational study. Adults, adolescents and children with a confirmed SCD diagnosis were included in the study by their referring doctor. Then, they were interviewed by phone about their socioeconomic status, about the impact of the disease on their lives and about their analgesic and psychoactive drug use., Results: The study population consisted of 872 patients (28% were minors). Seventy-two percent of adults were active, and all minors were in school. Many patients presented criteria of severe SCD. Seventy-five percent were homozygous SS, 15% were double heterozygotes SC and 8% were heterozygotes Sβthal, 87% received specific treatment, 58% were hospitalized at least once for vaso-occlusive crisis in the past 12 months, and the number of analgesic drugs taken averaged 3.8. Seventy-five percent of patients reported academic or professional consequences related to their SCD, and 52% reported social consequences., Conclusions: The impact of SCD on patients' lives can be significant, nevertheless their social integration seems to be maintained. We highlighted respect of recommendations regarding analgesic treatments and only a few patients used tobacco, alcohol or cannabis., Trial Registration: Clinical Trials, NCT02580565; https://clinicaltrials.gov/ Registered 16 October 2015., Competing Interests: The authors have declared that no competing interests exist.

Clinical complications of new synthetic drugs. Synthetic drug intoxication alerts have been at the forefront in recent years in France and abroad. We are thus witnessing an infinite production of derivatives of ancient psychoactive molecules belonging to various pharmacological classes, thus creating the name of new of synthetic products or "new psychoactive substances". Faced with evocative clinical symptoms, the clinician remains puzzled by the negativity of routine toxicological analyzes., Competing Interests: Les auteurs déclarent n’avoir aucun lien d’intérêts.
