Also, per the link, cheaper than emergency room visits and ambulance transports:
> But San Francisco public health officials found that the city saved $1.7 million over six months from the managed alcohol program in reduced calls to emergency services, including emergency room visits and other hospital stays. In the six months after clients entered the managed alcohol program, public health officials said visits to the city’s sobering center dropped 92%, emergency room visits dropped more than 70%, and EMS calls and hospital visits were both cut in half.
> Previously, the city reported that just five residents who struggled with alcohol use disorder had cost more than $4 million in ambulance transports over a five-year period, with as many as 2,000 ambulance transports over that time. [emphasis mine]
> The San Francisco Fire Department said in a statement that the managed alcohol program has “has proven to be an incredibly impactful intervention” at reducing emergency service use for a “small but highly vulnerable population.”
That's still cheaper than sending them to prison!
