Don't no one wanna blow the high
Frank is saying that people in the community know about how corrupt the law(police) is in their dealings with crackheads and dealers and no one does anything about it. No one stands up for the community. No one wants to “blow the high” its better to just leave it be.
In terms of their relationship, no one wants to tell them how bad it is, either. They don’t want to ruin their “high”. As the saying goes, ignorance is bliss.
