kokein

I’m not aware of a widely recognized term or concept named "kokein." To write a concise, neutral wiki-style article under 300 words, could you provide some context or a definition? For example, is kokein a real term in a particular field (biology, linguistics, geography, history), a brand or proper name, or a fictional concept you’d like me to create an article about? If you share a source or intended meaning, I can draft an accurate, neutral entry.
