Which of the following types of tobacco has highest nicotine content?
EXPLANATION
Micronutrient Chemistry
- Bidi Tobacco (Nicotiana rustica and specialized N. tabacum cultivars): Synthesizes and accumulates the highest nicotine content (typically 5.0% to 8.0% or higher) due to low topping, close spacing, and specific alkaloid biosynthesis genetics.
- Chewing Tobacco: Contains moderate to high nicotine (3.0% to 4.5%).
- Cigar Tobacco: Contains moderate nicotine (1.5% to 3.0%).
- Cigar Wrapper Tobacco: Contains the lowest nicotine level (0.5% to 1.2%) to provide mild burning aroma without harshness. (Correct answer: Option 1)
