Well, this article makes truly sense but should be placed in the right context, only a very small amount of K users experience this utter form of use.
Rather than mentioning the risks of addiction it'd be much better to spread info about the approach to Ket.
When starting with K, one should be aware that he's always submisse in this universe, and always will be. Ket is your safe host, with lodging, safety, serenity and peace. Ket takes responsibility for all your care, well-being and help. But Ket never discloses it's own true identity. Before the end and during the K-hole, Ket may make sense, but after, it's neutral.
Simply accept that you never can give it a placed place in your consciousness because you ain't getting to see everything. And neither receiving the finishing touch that should lead to a full understanding with the entire circle of enlightment after.
But it DOES have heavenly moments that may enlight many aspects of life you've to deal with, you may get fully rewarded for some things in life. Just without any full understanding or definition, but instictively.
It just doesn't happen in the K universe itself. So no one should search there after the open end.
Despite all the warmth, Ket is distanted from yourself, and always will be. Unlike shrooms/LSD/mesca/aya who are harmonisated and 'in you'. While Ket isn't anything/anyone/anywhere.
The pictures of Caduceus say a lot, they're are feared in life, but not so dramatically in the K-hole.
