Narcan, also known as Naloxone, is used as a nasal spray. Cities like San Francisco have initiated training on how to use the life-saving drug.

In 2022, the San Francisco Department of Public Health distributed 72,000 Narcan kits in hopes to address the city’s overdose problem. It also has trained more than 3,000 people on how to respond to an overdose.
