City health officials and police are trying to figure out what's causing a sharp increase in drug overdoses in Boston this year.
The Boston Public Health Commission said today the city had 32 suspected overdoses this past weekend - concentrated downtown and in East Boston and Dorchester. The same period last year saw just 8 overdoses.
In a statement, the commission said samples from street purchases by Boston Police "have not indicated more potency or drugs laced with particular potentially-fatal substances."
