My family speaks a related dialect (Southern Appalachian) , and I grew up in an area where many of my neighbors, teachers, and peers spoke AAVE (Charlotte). I can confidently say that you're misunderstanding the concept of double negation in dialects related to southern english. Specifically: Double negation is not mandatory, it's emphatic. There is nothing ungrammatical or confusing about saying "any" instead of "no" in that sentence. There is a slight difference in emphasis conveyed ("no drugs" emphasizes that the amount is none, and "any drugs" emphasizes the subject of "drugs"). It's also possible he just chose the the word "any" because he was trying to tailor his speech to a particular audience. Another similar example from my family's dialect would be the use of "might could" in place of "could" to convey uncertainty. It's commonly used, it adds additional context, but it would not be incorrect, weird, or misunderstood to just say "could".
