What is a drug fix slang?

Excuse me, but could you please clarify what you mean by "drug fix slang"? Are you referring to the colloquial terms or slang expressions that individuals who use illicit drugs might use to describe the act of obtaining or consuming their drug of choice? Or perhaps you're asking about the specific language that's associated with a particular drug or method of consumption? It would be helpful if you could provide some context or clarify your question so that I can give a more accurate and informative answer.
