A street name for heroin, Big H is the kind of coded language that emerged to discuss the drug without saying its name outright — useful in conversations where you don't want to be overheard or flagged. The 'Big' prefix suggests both the outsized impact of the drug and a kind of grim respect for its power. Like many drug euphemisms, it's been around long enough to appear in crime fiction, music, and harm-reduction discussions.
The documentary explored how Big H devastated small towns that had no resources to deal with the addiction crisis.
