Online retailers have been moving towards lower percentages for years. I started with a massive 30% (around 4 years ago) when I switched and I'm down to 1.5% because I believe there are some good benefits, similar to caffeine.

That's great to hear, honestly. Brands like Juul have (had?) very high concentrations.

I believe the % concentrations are apples and oranges when comparing a PG/VG based juice to nicotine salts. I thought the same when I saw how high the nic was, but I believe the actual % of nicotine absorbed is about the same for lower % PG/VG and seemingly high % nic salts
