Currently, nicotine in e-liquids comes mainly from three sources: tobacco extraction, other plant extracts, and chemical synthesis. These three sources differ in their properties and applications.

1. Natural Nicotine (Tobacco-Derived)
This is the most traditional method, with key details as follows:
Extraction Method: Involves direct extraction from tobacco leaves, usually using ethanol extraction or supercritical carbon dioxide extraction.
Advantages: Relatively high purity and a well-established flavor profile, which is why it's used in most traditional e-liquids on the market.
Disadvantages: Tobacco itself introduces trace plant impurities and characteristic aromas, which some people find reminiscent of real cigarettes.
2. Tobacco-Free Nicotine (From Other Plant Sources)
This source is rarely used commercially, with the following characteristics:
Plant Sources: Solanaceous plants like tomatoes, potatoes, and eggplants contain nicotine, but in extremely small amounts-several orders of magnitude lower than in tobacco.
Feasibility: While extracting it is theoretically possible, low efficiency and high cost make it commercially unviable.
Current Status: Very few companies pursue this route; the occasional "tobacco-free nicotine" product is more of a marketing gimmick.
3. Synthetic Nicotine
This type has grown in popularity in recent years, with key features including:
Production Method: Chemically synthesized in a laboratory, with a molecular structure identical to natural nicotine.
Advantages: Higher purity (free of tobacco-related trace impurities and odors), cleaner taste, and not subject to tobacco-derived nicotine regulations in some countries-favored by emerging e-liquid brands.
Disadvantages: Production costs are still slightly higher than those of natural extraction.
The three sources can be summarized as follows:
⑴ Tobacco extraction: Most mature and widely used method.
⑵ Synthetic nicotine: Purer and more flexible in application.
⑶ Other plant sources: Mostly theoretical and not commercially viable.
When buying e-liquids, consumers can check the packaging for labels like "tobacco-free nicotine" or "synthetic nicotine" to figure out its source.
