Nicotine Content from Cigarettes Submerged in Soda

Area of Science:

• Environmental Health
• Toxicology
• Analytical Chemistry

Background:

• Tobacco products, like cigarettes, are often extinguished in beverage containers.
• Accidental ingestion of these liquids has led to reported cases of nicotine poisoning, particularly in children.
• Understanding nicotine leaching from immersed cigarettes is crucial for public health risk assessment.

Purpose of the Study:

• To quantify nicotine concentrations in a beverage after immersing cigarettes.
• To investigate the relationship between nicotine levels, the number of immersed cigarettes, and immersion duration.
• To assess the potential toxicity risks associated with discarded cigarette beverages.

Main Methods:

• Unsmoked cigarettes were immersed in a cola beverage within a soda can.
• Samples were collected at various time points up to one week.
• Nicotine concentrations were analyzed using liquid chromatography-mass spectrometry (LC-MS).

Main Results:

• A mean nicotine concentration of 0.48 mg/ml was measured after 6 hours from one cigarette in 55 ml of cola.
• Nicotine levels increased significantly in the first 6 hours, then plateaued.
• A strong positive correlation was observed between nicotine concentration and both the number of cigarettes and immersion time.

Conclusions:

• Nicotine concentrations from immersed cigarettes in beverages can reach potentially toxic levels, especially for children.
• Both the quantity of cigarettes and the duration of immersion directly influence nicotine leaching.
• These findings highlight the dangers of improperly discarded smoking materials in accessible containers.
