The bottle I'm currently using came from
Vapor Country. 48mg and 60mg can be found at
Nhaler,
My Freedom Smokes and
DIY Flavor Shack.
As for being healthy
There have been several threads regarding the level of nicotine that one actually absorbs while vaping and what level can be considered as "safe". Depending on what type of math the various respondents in these threads have used, a case for healthy/safe, or not, has been made for every level of nicotine available.
Step back and look at these threads and the passion of some folks regarding how "right" they are and how everyone else is a fool is very comic/tragic.
I stay off of tobacco and maintain a clear head by vaping 36mg sunup to sundown.
That's what works for me. I made a huge effort to drop to 24mg last month that was a huge failure. After 2 weeks I was experiencing the classic nicotine withdrawal symptoms of irritability, lack of focus and concentration. Back to 36mg and voila, all good!
Many other vapers maintain with nic levels as low as 6mg and feel uncomfortable and even sick when they use stronger than 12mg.
These individuals have found what works for them.
BIG POINT is that we're all different with respect to what our body chemistry requires to maintain our nicotine addiction. That's one of the beauties of vaping, being able to try different levels of nicotine to find what's right for the individual.
Starting to look like a rant, sorry Dj.
Is it healthy to vape 48mg? Damn sight healthier than smoking tobacco!
EDIT: Just noticed your location Dj, thank you for all you do.
