How effective is JUUL 2 as a nicotine delivery device?
How Effective is the JUUL2 Vaping Device at Delivering Nicotine?
If you are a smoker who wants to switch to a less harmful alternative, you might have heard of JUUL, a popular brand of e-cigarettes that use pods that are pre-filled with nicotine salts to deliver a satisfying hit. JUUL has recently launched a new version of its device, called JUUL2, which claims to offer improved performance and flavour. But how effective is JUUL2 in delivering nicotine compared to other products, such as the original JUUL, IQOS (a heated tobacco product), and combustible cigarettes? In this blog post, we will review some of the latest scientific evidence on the nicotine delivery and subjective effects of JUUL2 and other products.
What is JUUL2 and how does it work?
Launched in early 2022, JUUL2 is a sleek and simple device that consists of a battery and a pre-filled pod. The e-liquid is heated by an integrated coil and turned into vapour that the user inhales. The e-liquid is formulated with nicotine salts, which are a form of nicotine that is more similar to the natural state of nicotine in tobacco leaves. Nicotine salts are supposed to provide a smoother and faster absorption of nicotine than freebase formulas, which is the most common form of nicotine in e-liquids.
JUUL2 is different from the original JUUL in several ways. First, JUUL2 has a larger battery capacity, which means it can last longer between charges.. Third, JUUL2 has a new range of flavours, which are compatible with both JUUL2 and JUUL devices. The flavours include Polar Menthol , Virginia Tobacco, Blackcurrant Tobacco and Summer Menthol.
How does JUUL2 compare to other products in terms of nicotine delivery?
One of the most important factors that determine the effectiveness of an e-cigarette in helping smokers switch is the nicotine delivery. Nicotine delivery refers to the amount and speed of nicotine that reaches the bloodstream after using a product. Nicotine delivery can be measured by analysing the blood samples of users before and after using a product, and calculating the nicotine concentration and the time to reach the peak level. Nicotine delivery can also be influenced by the user’s behaviour, such as the number and duration of puffs, the interval between puffs, and the inhalation technique.
A recent study by Goldenson and colleagues compared the nicotine delivery and subjective effects of JUUL2 in two nicotine concentrations (18 mg/mL and 40 mg/mL), JUUL in 59 mg/mL, IQOS in 18 mg/g, and combustible cigarettes in 40 adult smokers. The study used two methods of product use: ad libitum, which means the users could use the product as much as they wanted for 10 minutes, and controlled, which means the users had to take 10 standardised puffs for 5 minutes. The study also assessed the users’ ratings of satisfaction, craving reduction, aversion, and harm perception after using each product.
The results showed that nicotine delivery was greatest for combustible cigarettes, followed by JUUL2 in 40 mg/mL, IQOS, JUUL2 in 18 mg/mL, and JUUL in 59 mg/mL. Nicotine delivery from JUUL2 in 18 mg/mL was significantly greater than JUUL in 59 mg/mL after ad libitum use, which suggests that JUUL2 has a more efficient nicotine delivery system than JUUL. JUUL products were significantly more satisfying and effective at reducing craving than IQOS, which indicates that nicotine delivery is not the only factor that influences the user’s experience. JUUL2 in 40 mg/mL was significantly more aversive than other JUUL products, which means that it was too harsh and unpleasant for some users. - this entire section disregards TPD laws.
What are the implications of these findings?
The findings of this study suggest that JUUL2 is a more effective product than JUUL in delivering nicotine to the user, especially in the lower nicotine concentration of 18 mg/mL. This means that JUUL2 could potentially help more smokers switch to a less harmful alternative, as it could provide a similar or better nicotine hit than combustible cigarettes, while also offering a smoother experience than IQOS.
It is important to note that this study was conducted in a laboratory setting, which might not reflect the real-world use of these products. The study also had a small sample size and a short duration, which limited the generalisability and reliability of the results. More research is needed to confirm the findings of this study but judging by ET sales of the new version of the JUUL kit, it must be doing something right!
JUUL 2 is available to buy from ET UK, but is not available in our US store.Related Posts
