E-liquids commonly incorporate two main categories of nicotine: freebase nicotine and nicotine salts.

  • Freebase Nicotine: Manufacturers frequently utilize freebase nicotine in e-liquids. It exhibits a higher pH level, resulting in a harsher throat hit at elevated concentrations. Vapers who prefer a more robust throat hit often favor freebase nicotine.
  • Nicotine Salts: Nicotine salts, a newer addition to the vaping landscape, feature a lower pH level, delivering a smoother throat sensation, even with higher nicotine concentrations. Nicotine salts are especially appealing to those seeking a milder vaping experience, particularly at increased nicotine strengths.


Nicotine Strength and User Experience

E-liquids quantify nicotine strength in milligrams per milliliter (mg/ml). Common options include 3mg, 6mg, 12mg, and 18mg, each significantly influencing the user’s experience.

  • Low Nicotine Strength (3mg-6mg): Vapers seeking a nicotine experience that complements flavors without an intense nicotine hit often gravitate toward lower strengths. These levels mirror the nicotine content in light cigarettes.
  • Medium Nicotine Strength (12mg-18mg): Medium nicotine strengths cater to those transitioning from traditional smoking to vaping. They mimic nicotine levels in regular cigarettes, providing a moderate nicotine hit.
  • High Nicotine Strength (24mg and above): Heavy smokers or individuals with substantial nicotine requirements may opt for high strengths. However, caution is advised due to the potential for addiction associated with high-strength nicotine.

Vapers select their nicotine strength based on smoking history and personal preferences. It’s worth noting that nicotine levels also impact e-liquid cost and consumption, as higher strengths result in slower consumption. You can find comprehensive information on nicotine on Wikipedia.


Flavorings are a fundamental component of e-liquids, contributing to the diverse and enticing range of vape flavors available to users. Understanding the variety and types of flavors, as well as the associated regulation and safety concerns, is essential for vapers and regulators alike.
