Johnson Creek is by far my favorite
juice company. You should look into their procedures for creating their juice - it's really what everybody should be doing. They are setting the bar high, and come FDA regulation time I think they will be one of the industry leaders (the 'Marlboro' of e-juice), especially as this industry continues to grow.
A WORD OF CAUTION!!!!
I used their Red Oak line exclusively for the first few months I was
vaping (100% VG) and I can say it DESTROYED my atomizers. I don't know how some people out there talk about this like it doesn't happen - they must have different experiences... but I know, for certain, that using 100% VG juice absolutely ended my atomizers. For some reason I thought I needed to stick with 100% VG, but it simply was destroying every atomizer after a couple of days (2 weeks TOPS) of heavy
vaping. Now I use the PG juices, and I am extremely satisfied. Never going 100% VG again; I think the PG blends they use at JC are 70:30 PG:VG, which is ideal for atomizer life and vapor production.
Anyways - JC juices are phenomenal. I'd strongly suggest getting some Autumn Crisp - caramel-deliciousness, I love it. I also use their chocolate truffle and merango a lot (merango = strawberry). I've recently realized I'm not so into tobacco flavors, so I stick with heavy, thicker flavored juices, and I've been very happy with the products I get from JC. Oh, and mint truffle is great too. I stick with 1.8% nicotine (18mg). The cost is a little higher than what you get in other places - but seriously, do a little research on their production methods (they are very active on youtube - interviews with head chemists; tours of the lab; etc) and their standards. They take everything extremely seriously. You'll be impressed!
and no - I don't work for JC. I just love the company. Really wouldn't consider putting anything else into my lungs, knowing their standards.
