Oddly enough, I smoked similar to how I vape. Drew into the mouth then inhaled, versus drawing straight into the lungs.
I think since people smoke and vape differently than one another, and in varying amounts, it will be different for everyone.
I was actually afraid that the moisture from vaping would prevent tar and crap from coming out. I haven't coughed up much, but got that froggy throat thing going on still after 2 months.
Since pure water is the bodies solvent, it's critical for removing any impurities from the body (including the lungs). It can't be overstated. I have no idea how much you drink so this is not directed at you, but all of us. Drink on!
