Case Report Suggests Tirzepatide May Induce Sudden Smoking Cessation

A case report describes a 53-year-old woman with type 2 diabetes who abruptly stopped smoking after starting tirzepatide. She reported cigarettes tasting abnormal, leading to disgust and nausea. This observation suggests a potential novel mechanism where GLP-1 receptor agonists like tirzepatide might alter reward pathways and behaviors associated with nicotine use, warranting further investigation into this unexpected effect.
