Kublacaine is the drug cocaine would be if it stopped messing around with mere delusions of grandeur, and just went for full on megalomania. It is commonly described as ‘an ego-enhancing drug’, and this is true in much the same way that it would be true to describe gasoline as ‘a fire-enhancing flammable’.
It was immensely popular during the so-called Anarchera of the multiverse, where Kublacaine was much prized as a way of avoiding one’s mind eating itself out of boredom during long and lonely space voyages. It was also commonly used as a recreational and social drug, which might sound like a terrible idea to you, but then, you’ve never taken Kublacaine, have you?
