I can say that the nicotine has a noticeably stronger effect on me, although there's less throat and lung hit than my regular DIY with 36mg/ml USP Nicotine. I can't tell if it's due to better bioavailability of Nic Salts or that it's just that 50mg/ml is a LOT of nicotine. I'm not getting any nicotine buzz kind of feeling. It's more like I feel a bit winded after a couple of draws.
What sort of a setup are you vaping your 50mg/mL e-liquid in? What type of atty, number of coils, coil resistance, and devise power setting? Keep in mind; the Juul pod design (using the 50-60mg/mL liquids) were formatted for single coil, high resistance, low wattage/temperature, vaping.
Based on Juuls website literature (
FAQ page):
--A Juuls pod contains 0.70mL of liquid.
--one pod ≈ 1 pack of cigarettes
--Juuls on-line ordering restricts max pod purchases to 15 packs (4 pods to a pack), or 60 pods a month. Therefore one can deduce that maximum consumption Juul expects/condones is to be 2 pods/1.4mL liquid per day.
So, if you are using a more commonly found setup used today; with low sub-ohm multi-coil builds, on high power high-temp producing devices, that consume much higher volumes of liquid (5mL, 10mL, 15mL, ???) per day; and trying to use a Juul-comprarible strength... I would think it being similar to a beer drinker, filling his beer mug with 80 proof whiskey, and trying to drink it the same manner he drinks beer... "it ain't gonna be pretty!"
As for the "breathless" feeling you are getting; it sounds exactly the same as the feeling I got/still get when I tripled my regular (freebase) nicotine (went for 6 to 18mg/mL), for the express purpose to reduce my e-liquid consumption.
When I was vaping 6mg/mL, I constantly had my rig at my mouth, and was forever chain vaping. After bumping to 18mg/mL, I could only get 3 or 4 puffs, and I got/still get that almost "breathless" feeling. I interpret it as my body saying "Hey; I've had enough for now!" My desire to keep vaping is gone for the moment, I don't vape for a while, and the feeling passes as fast as it came on.
Everything I've ever read says that as nicotine is oxidized by UV light, it and/or it's carrier will darken/amber over time.
Not exactly correct. UV (like heat)
accelerates oxidation. Oxidation can take place in the absence of UV (think of sunken ships rusting well below the reach of natural sunlight). This is why amber bottles, dark freezers, and all the other things we do to protect our nic concentrate stashes, will greatly
slow the aging process, but not stop it entirely.
However (as I understand it), you are correct that nicotine salts are more stable, and less susceptible to oxidation than freebase nicotine is.
