A US report has highlighted a sharp deterioration in conditions in one of America's most troubled neighbourhoods, with photographs reportedly showing homeless residents left in a "zombie-like" state after using a new and dangerous street drug. The images have caused alarm, pointing to a fresh wave of substance abuse compounding long-standing problems of poverty, addiction and public disorder in the area. The story underscores the ongoing struggle US cities face with synthetic and highly potent drugs circulating among vulnerable, often homeless, populations.

The article itself, as provided, does not detail the specific neighbourhood, city or the name of the drug involved, nor does it give figures on the number of people affected or any official response. It largely consists of unrelated Daily Mail site content and navigation links rather than substantive reporting on the incident, meaning key facts such as location, drug type and health authority comment are not available in this text.
