Can't say I understand lung hitting either apart from bigger clouds then mouth to lung but a few years ago when all those experts were coming out with "nicotine isn't the problem for quitting its the whole ritual the hands and mouth" (well in the UK) I bought a pack of herbal things trying to quit omg they smelt like a bonfire and tasted like a week old sock but it did make me realise the biggest thing I missed was the throat hit. I think that's why vaping worked as well for me I take an inhale and get that lovely hit and it's why I'll be vaping till I croak.
Years ago I got thrown out of a pub because the landlord thought the herbal cigs smelled like something illegal!
