Omissions

• The data comes from a specific 2023 study by the French Addictovigilance Network, covering cases from 2015-2020
• The study found 75.4% had neurological disorders - substantially higher than just 'more than half'
• The same study also found 82.5% had substance use disorders
• The study was published in Frontiers in Public Health in 2023
• The MEP understated the proportion - it's not just 'more than half' but three-quarters of cases
