Funny thing is, if I remember right, blu's thing was that they didn't use pg at all, but a combination of other ingredients, in this order

istilled Water, Nicotine, Natural & Artificial Flavors, USP Glycerin, Citric Acid. Just found that on their site
Not really sure if its because of the (unfounded) antifreeze connection, or because theyre sensitive to allergies or if its just that vg produces an a$$ton of vapor. I like to think its the latter 2. A vg base, I would think, would burn out the carto faster. See post 11. But if the element is surrounded by the juice, maybe that's not such an issue. Idk.
Me, I go right down the middle, 50/50 pg/vg. Gives me a mild throat hit and a gratifying amount of vapor that I can hide behind

If you want to "recreate" the taste of the blu, Johnson creek makes the juice that blu puts in their cartos.
You're gonna hear a lot of folks say"I can't believe you use a blu". It's whatever works for the individual. I've got a friend that i gave all my old blu stuff and he's still chugging along, half vaping and half smoking-whatever works and reduces harm. I would however suggest getting blank 501? 306? Cartos that u fill yourself, just for the economy of it
Again, if I misinformed, please feel free to correct me. Just trying to help
