After a blood pressure cuff tightened and loosened around his arm at a packed Q House gymnasium, Orlando got a reality check.

One person died following 19 reported overdoses that took place across the city between Sunday and Tuesday. According to one of the city’s front-line addiction healthcare workers, there were also at least four ​“saves” during that same time period — including by someone in a Congress Avenue barbershop who rushed out into the street to use the life-saving medication Narcan.
