Background: The prevalence of recreational drug use in myocardial infarction (MI) patients without standard modifiable cardiovascular risk factors (SMuRF) namely hypercholesterolemia, hypertension, diabetes and smoking, remains unknown.

Methods: All patients enrolled in The Addiction in Intensive Cardiac Care Units (ADDICT-ICCU) study, a French multicenter prospective observational study which systematically assessed the use of recreational drug within 2 h of admission, and presenting with MI but without known coronary artery disease were included. We compared patients with and without SMuRF.

Results: Among the 243 patients included, 31 (12.8 %) had no documented SMuRF. Recreational drugs were detected in 1 SMuRF-less patient (3 %) compared to 29 (14 %) patients in those with ≥1 SMuRFs (p = 0.17). When considering only ST-elevation MI patients (n = 77), none of the SMuRF-less patients (n = 13) had detected recreational drugs contrary to those with ≥1 SMuRFs (12 %, p = 0.40).

Conclusion: Recreational drug use was scarce in SMuRF-less MI patients and not different when compared to those with ≥1 SMuRF. Further research to explore non-traditional risk factors as an important cause of first MI are still needed.

The number of people suffering from Substance Use Disorder (SUD) worldwide has increased 45 % compared to the last decade according to the latest United Nations World Drug Report. This staggering increase, partly due to the recent COVID-19 pandemic, further raises the social and economic burden for nations. Prevention and treatment, two of the main strategies employed to curb the increase in SUD, have shown limited success despite our increasing understanding of the underlying processes of SUD.

The global opioid crisis is a public health emergency characterized by the widespread misuse of opioid drugs, leading to high rates of addiction, overdose, and death. Initially driven by the over-prescription of opioid painkillers, it has evolved into a worldwide epidemic exacerbated by the rise of potent synthetic opioids. Benzimidazole opioids ('nitazenes') are one group within this class of compounds that have garnered increasing attention in recent years due to their addictive potential and growing presence in illicit drug markets.

Topical poultices and applied medical devices that can relieve a variety of cervical vertebrae and lumbar vertebrae pain may have illegal additives of pharmaceutical drugs or analogues have additional health risks, but customers may not be aware of what they are using. National Medical Products Administration reviewed and approved "Supplementary test method for identification and content determination of 17 chemicals in affixed medical devices" drafted by Shandong Provincial Institute of Medical Devices and Drug Packaging Inspection in January 2022, but the test method is simple in sample processing and difficult to extract the chemical components in the paste that may cause the phenomenon of missing detection of most illegal added chemical drugs. In this work, the sample handling and extraction methods have been improved and optimized, the content of illegal added chemicals in 47 batches of affixed medical devices was determined by HPLC-MS/MS method and was detected in 37 batches, and the non-steroidal anti-inflammatory drug nimesulide and aspirin were detected in most samples.
