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’s One Nation Proposes 75% Tobacco Tax Cut, Says Lower Prices Could Hit Illicit Market
Australia’s One Nation Proposes 75% Tobacco Tax Cut, Says Lower Prices Could Hit Illicit Market
Australia’s One Nation party has proposed cutting tobacco excise by 75%, arguing that lower legal cigarette prices could narrow the gap with illicit tobacco and reduce demand for black-market products. The proposal comes as Australia continues expanding enforcement against illicit tobacco supply chains through border controls, retail inspections and organised-crime investigations. Supporters argue high taxes have contributed to illicit-market growth, while opponents warn that lower tobacco prices could undermine public-health goals. The proposal is a party policy position and has not been adopted by the Australian government.
