Quickest method, but most difficult to do properly. It's what I do and it takes me about 3 seconds to take 5 grams. What you do is toss a few grams in your mouth, take a sip of water (while the kratom is still in there), then mix it around in your mouth and swallow it. Kratom doesn't dissolve in water very well, so make sure you mix it around in your mouth well enough so it doesn't result like a cinnamon challenge. Maybe try 1 gram at a time on your first try.
