One average areca nut (~2 g) contains ~5-8 mg arecoline. Calcium hydroxide or slaked lime is traditionally added to basify saliva and improve buccal absorption, but greatly increases oral carcinogen formation. Chronic areca nut use is classified as a Group 1 carcinogen by IARC with strong evidence for oral cancer, submucous fibrosis, and systemic health effects. Commercial 10 mg HBr products provide cleaner stimulation than traditional betel quids but carry cancer risk with long-term use. First-aid for cholinergic excess: 0.5-1 mg atropine IV or oral diphenhydramine, fluids, and monitoring.
