Lotta people have this notion that "salt" intrinsically means high nic levels. There's also the notion that "sub ohm" intrinsically means DL-huffing huge, lung-busting hits. Neither of these is necessarily true.
Of course if someone does take big, DL hits of 50 mg salt from a high powered device, they're probably going to have a bad time. But salt juice can be found in (or made) at pretty much any strength.
Oh, and "sub-ohm" doesn't mean a person uses a DL vaping style either. I haven't built anything over an ohm in the better part of five years now, yet my vaping style is very much MTl and the 'l' is lower-case for a reason.
