You will have to use higher strength nicotine more frequently using a cig-alike compared to a larger device that has the power to deliver more vapor, therefore, more nicotine.
This study done by Dr. Farsalinos tells the tale comparing a cig-alike with a larger, more powerful device using 18 mg juice, Nicotine absorption from electronic cigarettes. Even puffing on a cig-alike for an hour doesn't produce as much nicotine as smoking a cigarette for five minutes.
If you absolutely insist on using a cig-alike the Joye e-Roll is probably the the best of that type. However, I would strongly encourage you to get a larger device as well if you are serious about quitting cigarettes. An Innokin VV 3.0 paired with a mini Kanger Pro Tank isn't terribly large and will allow you to adjust the warmth of your vape which affects taste and vapor production, both which can be important factors in finding a satisfying vape.
I looked forward to reading this with interest, but am I the only one that finds this part very "unscientific" for lack of a better word?
". At each visit the e-cigarettes were filled with identical 18 mg/ml nicotine concentration liquid and the participants were instructed to take 10 puffs during the first 5 minutes of "vaping" and then to puff as they felt like it for the next hour."
So....puff as they felt like it. One person may take 30 puffs in an hour and another take only an additional 5? They may know something about the initial nicotine rise in the bloodstream but not what happens over that hour period.
I do not think it is unreasonable to think that people will also vape different frequency with different devices, and this "study" did not account for that except for the first five minutes. In my mind, what would have made more sense was identical puff numbers in identical amounts of time from each device. Not just identical for the first five minutes. Why did they do this? It seems they missed out on an oppurtunity to gain more info.
