ADVERSE REACTIONS 
Case report of 58 years women smoked heavily 
changed to menthol containing cigarettes. After 
three months she became irritable and 
quarrelsome, in contrast to her former placid 
good-natured state, and had gastrointestinal 
upset with occasional vomiting. Her speech 
became thick and she developed a tremor of the 
hand and an unsteady gait. On one occasion 
mental confusion and depression occurred and 
she was admitted to hospital with a toxic 
psychosis that was considered to be due to 
menthol addiction. Within 17 days of the 
withdrawal of menthol cigarettes, she became 
normal in every respect without 
specific treatment.
