Wife convicted of poisoning husband with nicotine in South Korea
A Korean man died from nicotine poisoning, and his wife was suspected of intentionally feeding him the substance.

On a morning in May 2021, a Korean man named A unexpectedly passed away in his home at approximately 7 a.m. After conducting an autopsy, it was determined that the cause of death was nicotine poisoning. As a result, A's wife, B, was named as a suspect in a criminal investigation by the authorities.


Miancha, baizhou, and nicotine solution.


According to reports, A had left work early the day before his death because he was feeling unwell. In a conversation with his wife, B, she informed him that the cause of his illness might have been the expired honey added to his breakfast tea. A was taken to the emergency room shortly after returning home and underwent simple tests and rest before being discharged. He then passed away the following day.


According to the prosecution and the police, it has been suggested that the amount of nicotine found in A's body and their dietary intake indicate that B fed A liquid nicotine three times. It has been reported that B gave A tea containing nicotine in the morning, rice soup containing nicotine when he returned home, and water mixed with liquid nicotine after A returned from the emergency room.


The wife stated that there was no reason to kill her husband.


B claims that "this is a medical accident, she did not kill her husband, and there was no reason for her to do so." The police presented evidence that B had purchased nicotine liquid from a nearby vape shop a few days before the incident. B initially stated that she had bought it for her husband who smoked. However, after investigating the people around A and her credit card usage, the police discovered that A quit smoking eight years ago. B then changed her story and claimed that she had bought the liquid for herself to smoke.


Furthermore, B claims that her husband, A, attempted suicide several months ago and that suicide-related search terms were found on his phone. During this same time, B was involved in a long-term extramarital affair with another man while also accumulating debts exceeding 100 million Korean won.


Most people in the area reported that A's husband also became aware of this fact and, as a result, the couple had a serious argument. The husband also has over 100 million Korean won in life insurance.


According to the judiciary department, the motive for B's murder, which included adultery and debt, was deemed sufficient.


The judiciary department believes that B has a criminal motive.


Firstly, B, the wife, revealed that she had conflicts with her husband in order to maintain a long-term relationship with her lover. If her husband were to die, it would solve her financial difficulties. Furthermore, information left behind by A indicated that he worked hard to support himself and his beloved son, in addition to his profession. There is no reason to believe that he would have made such an extreme choice, given the absence of a suicide note.


In the end, B was sentenced to 30 years in prison and is currently serving the sentence.

Australia Brings in Deloitte to Support Illicit Tobacco and Vape Enforcement Across Data, Processes and Project Delivery
Australia’s Department of Home Affairs has hired Deloitte to provide data analytics, business-process, communications and project-delivery support to the Office of the Illicit Tobacco and E-Cigarette Commissioner. The government says Deloitte personnel do not provide policy advice to the Commissioner or the Australian government, with policy development and decision-making remaining with public officials. The arrangement has nevertheless drawn scrutiny because Deloitte has previously provided professional services to several tobacco and vaping companies.

China Tobacco Zhejiang files patent for pressure-triggered, on-demand oral nicotine release
China Tobacco Zhejiang files patent for pressure-triggered, on-demand oral nicotine release
China Tobacco Zhejiang Industrial Co., Ltd. has filed a patent application for an oral nicotine delivery product designed to let users actively adjust nicotine release. The product embeds two types of nicotine reservoirs with different wall thicknesses and positions inside a deformable matrix. Pressure applied with the tongue or lips can rupture the reservoirs and accelerate nicotine release. In simulated oral tests, several patent examples showed sharply higher peak nicotine release rates as applied force increased from 0 N to 1 N and 3 N. The filing explores a shift from preset release profiles toward user-triggered nicotine delivery.

As Regulators Focus on Nicotine Pouch Child Safety, Safeguard Pursues an External Packaging Route
As regulators pay closer attention to child safety in nicotine pouches, manufacturers face a practical challenge: how to strengthen child-resistant packaging without unnecessarily reworking products, production lines and regulatory submissions already in place. In a written interview with 2Firsts, Chemular detailed Safeguard’s external packaging approach, its customer-specific testing requirements and possible PMTA pathways. The model remains early-stage, but it offers a new way to think about an increasingly important regulatory and manufacturing issue.
