Greater nicotine flux, or the rate that an e-cigarette emits nicotine, was associated with higher e-cigarette dependence among users of pod-based e-cigarettes like JUUL, according to recent Truth Initiative research published in Addictive Behaviors.
The pilot study examining the impact of e-cigarette device and liquid characteristics on nicotine dependence also found that younger age was significantly associated with e-cigarette dependence, underscoring concerns about e-cigarettes effectively delivering higher amounts of nicotine to young people and encouraging addiction.
The findings speak to the need for regulations limiting overall nicotine delivery, rather than laws governing individual e-cigarette device components in an environment when local and federal legislation cannot keep up with quickly evolving e-cigarette technology.
E-cigarettes make nicotine delivery more efficient
Before JUUL was introduced in 2015, the most popular e-cigarette products contained nicotine strengths of between roughly 1% and 2.4%. When JUUL debuted, its pods contained 5% nicotine strength, with one JUUL pod containing 20 cigarettes worth of nicotine. The maker of JUUL claims its nicotine salt formulation increases the rate and amount of nicotine delivered into the blood, compared with other formulations. The company has claimed the product delivers nicotine up to 2.7 times faster than other e-cigarettes.
