"Some drug dealers often confuse the dosage specifications and types of drugs during the process of dismantling and reassembling 'reflux drugs'. Children taking adult drugs can be life-threatening. Patients who need to promote blood circulation can directly die if they take clotting drugs. Some special drugs for mental anesthesia and pain relief are even sold as drugs to young children who pursue novelty..." On April 26th, the National Medical Security Administration reported the serious consequences of' reflux drugs'. In recent years, many drug traffickers have induced insured individuals to participate in drug sales through "high price recycling". This kind of disguised recovery of drugs purchased by insured individuals after enjoying medical insurance reimbursement, which are then resold in a different way, is called medical insurance "return drugs". Regarding the harm of "reflux drugs", the National Medical Insurance Administration reported a case: Huang from Longyan City, Fujian Province, contracted a drug addiction but had no income, and embarked on the path of "selling, raising, and sucking". She repeatedly sold drugs such as tramadol hydrochloride, federal cough syrup, and otin cough water to school students and young people in society for huge profits through mailing, direct delivery, and direct selling at her rented place. Later, she was arrested and brought to justice by the public security organs. In addition, some drug dealers sell real drugs to small clinics that use scattered medications, and then sell fake drugs to pharmacies in real medicine boxes. In this way, they confuse fake drugs with real ones. If patients accidentally take them, it not only affects the treatment effect, but also may endanger their lives! "Returned drugs" may also become "expired drugs" because the expiration date of the drug is not directly printed on the tablet. Many drug dealers remove expired or expired drugs from their original packaging and put them in new drug boxes. Patients can only see the new date on the new drug box and are not aware that they have taken expired drugs. Such extravagance can delay the condition, or even endanger lives! Some drug dealers also use "return drugs" to deceive insurance. The National Medical Insurance Administration has reported that obtaining drugs through excessive or repeated dispensing before reselling them to drug dealers constitutes fraudulent insurance fraud. In 2020, the Medical Insurance Bureau of Jinhua City, Zhejiang Province, discovered through big data analysis that the medical insurance data of blood friend patient Hu Mouliang was abnormal. After in-depth investigation, it was found that Hu Mouliang held multiple medical insurance codes and falsely prescribed hemophilia treatment drugs Baiyinzhi in multiple hospitals. Later, he posted drug advertisements in the national hemophilia group, selling the drugs at prices ranging from 10% to 20% for profit. Hu Mouliang was ultimately sentenced to ten years and six months; His wife knowingly assisted him in prescribing and sending medicine, but she could not escape legal sanctions. The National Medical Insurance Administration stated that the direct sales and indirect auxiliary sales of "return drugs" by insured persons are both fraudulent insurance practices. According to Article 41 of the Regulations on the Supervision and Administration of the Use of Medical Security Funds, if an individual uses the opportunity to enjoy medical security benefits, resells drugs, accepts cash or physical returns, or obtains other illegal benefits for the purpose of fraudulently obtaining medical security funds, resulting in losses to the medical security funds, the online settlement of medical expenses shall be suspended for 3 to 12 months, and a fine of 2 to 5 times the amount fraudulently obtained shall be imposed. If the amount involved is large and the circumstances are serious, it may also constitute the crime of fraud. In response to drug traffickers, national ministries have also launched a heavy attack. In February 2024, the Supreme People's Court, the Supreme People's Procuratorate, and the Ministry of Public Security jointly issued the Guiding Opinions on Several Issues Concerning the Handling of Criminal Cases of Medical Insurance Fraud
