Addictovigilance is a health vigilance dedicated to the survey of medicinal or illicit psychoactive substance use disorders (SUDs). France is the only European country to have a vigilance system ...specifically dedicated to substances with an abuse/addiction potential. The French Addictovigilance system is organized in a network of regional tertiary centres (called Abuse and Dependence Monitoring Centres, CEIP‐Addictovigilance) and works in close collaboration with Regional and National health authorities. Because of the essential and unavoidable nature of their practice in the French Healthcare system, general practitioners (GPs) are key actors to identify and track Addictovigilance signals. They have been involved in several of the pharmacoepidemiological surveys implemented by the French Addictovigilance Network (FAN). Now, they increasingly participate in clinical research projects and studies. In this article, interactions between GPs and the FAN are illustrated with two examples: patients on opioid substitution treatment and patients on opioid analgesics. Collaborations between GPs and the FAN could be further potentiated. In particular, more effective communication on psychoactive SUDs including abuse/addiction is necessary to optimize the implementation of preventive measures for patients on psychoactive substances medications, and to improve the attitudes of GPs and more widely health professionals in the management of any psychoactive user suffering from SUDs. In addition, both adapted training and improved collaborative research could contribute to the optimization (safety, quality) of professional practices.
•We have only just begun to characterize cannabinoid hyperemesis syndrome.•French cases display the same characteristics as the international literature cases.•There is a cannabinoid hyperemesis ...syndrome outbreak in France.
Cannabinoid hyperemesis syndrome is a variant of cyclical vomiting syndrome in a context of chronic cannabis usage. Our aim was to compare French cases to those identified in the international literature in order to further our knowledge of the clinical criteria, pathophysiology and treatments for cannabinoid hyperemesis syndrome.
We analysed cases reported in the international literature up to 30 June 2017, obtained from the MEDLINE, PsycINFO and The Cochrane Library databases; we selected relevant articles based on title and abstract. We also analysed cases of cannabinoid hyperemesis syndrome reported to the French addictovigilance network.
A systematic search through the three databases enabled us to identify 137 articles. Finally, 55 articles were selected as they involved reported cases. In total, 113 cases were reported in these 55 articles. We were thus able to analyse 29 reported French cases of cannabinoid hyperemesis syndrome. Cannabinoid hyperemesis syndrome mainly affects young male subjects who have been smoking cannabis daily for several years. Taking hot baths or showers is the most effective means of relieving the symptoms, while antiemetics and dopamine antagonists do not appear to effective for relieving nausea and vomiting.
French cases display the same characteristics as the cases identified in the international literature. The pathophysiology of cannabinoid hyperemesis syndrome is unclear and several hypotheses have been put forward in the literature. We have only begun to characterise the syndrome, though there is an outbreak of cannabinoid hyperemesis syndrome in France.
Purpose: The aim of this study was to describe the extent of methylphenidate (MPH) abuse and characterize its patterns by following several cases involving intravenous administration of crushed MPH ...tablets. Methods: First, a drug reimbursement database (covering 4 million inhabitants) was explored to assess the magnitude of MPH abuse among the general population, and second, a specific study based on individuals with drug dependence was performed to describe abusers' characteristics (n = 64), patterns of abuse and clinical implications. Results: From 2005 to 2011, the number of patients who were dispensed MPH at least once increased by 166%. The patients with ‘deviant' patterns of MPH consumption were mainly male adults with opiate maintenance treatment reimbursements. MPH abusers had precarious living conditions. Half of them consumed MPH daily by intravenous route and reported amphetamine-like effects (cardiovascular events, weight loss, psychiatric adverse events). Conclusion: Given the increase of MPH use, it is important to warn the scientific community about possible MPH abuse, especially in individuals with drug dependence. This study has facilitated public health intervention and dissemination of information related to MPH abuse among health care professionals at local and national levels.
Aims
The French health authority (ANSM) is responsible for monitoring medicinal and other drug dependencies. To support these activities, the ANSM manages a network of 13 drug dependence evaluation ...and information centres (Centres d'Evaluation et d'Information sur la Pharmacodépendance ‐ Addictovigilance ‐ CEIP‐A) throughout France. In 2006, the Nantes CEIP‐A created a new tool called the EGAP (Echelle de GrAvité de la Pharmacodépendance‐ drug dependence severity scale) based on DSM IV criteria. This tool allows the creation of a substance use profile that enables the drug dependence severity to be homogeneously quantified by assigning a score to each substance indicated in the reports from health professionals. This article describes the validation and psychometric properties of the drug dependence severity score obtained from the scale ( Clinicaltrials.gov NCT01052675).
Method
The validity of the EGAP construct, the concurrent validity and the discriminative ability of the EGAP score, the consistency of answers to EGAP items, the internal consistency and inter rater reliability of the EGAP score were assessed using statistical methods that are generally used for psychometric tests.
Results
The total EGAP score was a reliable and precise measure for evaluating drug dependence (Cronbach alpha = 0.84; ASI correlation = 0.70; global ICC = 0.92). In addition to its good psychometric properties, the EGAP is a simple and efficient tool that can be easily specified on the official ANSM notification form.
Conclusion
The good psychometric properties of the total EGAP score justify its use for evaluating the severity of drug dependence.
Parachuting (also called bombing) is a method of drug delivery where illicit drugs or medicines are ingested after wrapping the substance. There are little data describing parachuting in the ...literature. To provide a description of this practice, all cases of parachuting reported to the national addictovigilance network up to 31 December 2014 were identified from spontaneous reports and specific surveillance programs. Cases were described according to the type of substance used, patient age and gender, type of complications, context of use and year of the event. Forty‐five cases of parachute use were identified and most (n = 43) occurred after 2011. Patients were mostly men (60%), and mean age was 28.9 years. The context of use, known in 19 cases, was mostly recreational. Complications were present in 24 cases, of which eight were serious. The substance was supposed to be 3,4‐methylenedioxymethamphetamine (MDMA) in the majority of cases (64.4%); research chemicals were more involved in the most recent years. The physical form was mainly granular (51.6%). The wrappers were a cigarette paper (nine cases) and in one case plastic package; in the other cases, the term of parachute was used without further details. The reason for use was not explained in the majority of cases; two patients indicated using a parachute for faster effect than with a methadone capsule. Clinicians should be aware of this delivery form as the results suggest that it is common and can involve a great variability of drugs.
Importance The DRAMES (Décès en Relation avec l’Abus de Médicaments Et de Substances) register is a database of drug-related deaths with the aim of identifying the psychoactive substances associated ...with and estimating the trends in these deaths. Our novel approach is based on the collection of data on all deaths for which toxicology experts have performed analyses. Objective To describe drug-related deaths in France and report trends over an 11-year period. Design, Setting, and Participants This case series used a national register to assess 4460 drug-related deaths that occurred from 2011 to 2021 in France. Data analyses were performed from January 1, 2012, to December 31, 2022. Main Outcomes and Measures Demographic characteristics; medical and substance abuse history; forensic autopsy findings; and toxicology reports. Results Among the 4460 deceased individuals (mean SD age, 37.8 10.5 years), the mortality rate was highest among men (sex ratio, 4.4:1). Of the deaths involving a single or predominant drug, the legal substitution product, methadone, was the leading cause of death during the entire study period, ahead of heroin—44.7% and 35.9% for methadone vs 15.8% and 21.8% for heroin in 2011 and 2021, respectively. Between 2011 and 2021, most of the drug-related deaths shifted from licit to illicit drugs, and statistically significant variations were found for buprenorphine, cocaine, heroin, methadone, and other licit opioids. Deaths related to polydrug use increased from 23.2% in 2011 to 30.6% in 2021. In this context, opioids remained associated with most deaths, with at least 1 opioid being involved in approximately 9 of 10 cases (85.9%) in 2021. However, the main trend was the dramatic increase in drug combinations with cocaine, from less than one-third of cases in 2011 (30.8%) to more than half in 2021 (57.8%). Conclusions and Relevance This case series assessment of 4460 drug-related deaths found that opioids used alone or in combination were the main contributor to drug-related deaths, despite having a lower prevalence than other drugs. This finding is similar to that of other countries; however, in France licit methadone was the leading cause of opioid-related deaths (ahead of heroin) during the study period. Deaths associated with use of cannabis, new psychoactive substances, and stimulants (including amphetamine-type stimulants and cocaine, especially in combination) have increased and should be closely monitored.

Introduction. Body packing is a well-known means of narcotic carriage across international borders. The most common drugs carried are cocaine and heroin. Case descriptions. We describe 2 cases of ...cannabis body packing which occurred the same year in the South of France, one with complications: a 45-year-old male went to emergency for abdominal pain. A plain abdominal x-ray revealed multiple foreign bodies in the gastrointestinal tract. It was confirmed by abdominal CT. The laparatomy confirmed peritonitis secondary to colonic perforation, and 34 filled condoms packages were extracted. After calling poison centre, toxicological analysis was performed on one package. The resin wrapped in cellophane contained 15% tetrahydrocannabinol (THC). The patient was discharged on day 12. Discussion/Conclusion. Cannabis body packing is rarely reported, and the only known complications have a mechanic etiology. Plain abdominal x-ray is the best method for detection and it can be confirmed by abdominal CT and toxicological analysis. Cannabis is the most important illicit drug used in the word. Also cannabis body packing is probably underestimated. Health care practitioners should be aware of the possibility of body packing when someone coming back from abroad complains of abdominal pain.
A great diversification of drugs of abuse has been observed in recent years, both in the populations using them and in the types of drugs. Although dependency and psychiatric disorders associated ...with the abuse of these substances is well known, somatic complications, uro-nephrotoxicity in particular, are less recognized. We propose here an overview of the products used by drugs abusers in France, through the analysis of the national pharmaco-epidemiological study Observation des produits psychotropes illicites ou détournés de leur utilisation médicamenteuse (OPPIDUM). Among the 5003 patients who participated in this survey, 84% were on prescribed psychoactive substances, with indicators of abuse in 28% of cases; more than half of these patients had also been using drugs of abuse (mainly cannabis) in the previous week. We then describe the main urological and renal toxicities of these drugs, in particular of heroin, cocaine, cannabis, ecstasy, LSD, amphetamine, new designer drugs, ketamine and opiate substitution treatment. We finally present a pharmaco-epidemiological survey of patients hospitalized for drugs complications in nephrology at the university hospital of Marseille. Between 2000 and 2015, 22 patients aged 18 to 57 years were hospitalized for renal adverse effects of drugs of abuse, such as glomerulonephritides, focal segmental glomerulosclerosis, acute kidney injury or chronic kidney disease. The somatic complications of drugs participate in their dangerousness and should be a red flag. They should be systematically reported to the addictovigilance national network to allow the improvement of information given to the patients and the medical community, and to adapt the prevention and risk reduction policies.
