It is the 36 mg I got here they were making a big deal over. Not the 18 mg. I know it is a high amount and I don't vape on it all the time. But hell sometimes I need that high amount. lol. Plus I am not going to waste free gifts from another friend.
I vaped 36 mg for well over a year when I started vaping, chain vaping at times to beat the craving. Didn't reduce drastically, went to 30 mg for a long while, and now after 4 years I find that 12mg - 15mg is enough to satisfy me. I smoked 1-1/2 PAD, nothing excessive or unusual.
Use what works to keep yourself from smoking. And read through this study by a well respected doctor....Nicotine absorption from electronic cigarette use: comparison between first and new-generation devices : Scientific Reports : Nature Publishing Group it discusses nicotine levels necessary for successful e-cig useage. (give a copy to your sister)
One of the study's findings was....
Based on the results of this study, showing very low levels of nicotine absorption from using ECs in a similar way to smoking one tobacco cigarette, it seems that nicotine levels in EC liquids should be close to 50 mg/ml in order to approximate nicotine delivery from smoking. This could also result in reduced daily EC use and liquid consumption, since the amount of nicotine needed by each user could be obtained by reducing the time and intensity of EC use.
