Supervisors Joel Anderson and Jim Desmond cast the dissenting votes.
Anderson said he wasn't against Fletcher's proposal, but wasn't comfortable "voting and then later learning that all the clinics are going to be located in my district.'' He said he wanted to see a plan first, adding, "Is there some middle ground? I hate to vote against this.''
Desmond said that giving out needles still has the appearance of promoting drug abuse.
"I would like to see an emphasis on prevention,'' he added. "I see that needle exchange (would) promote health among those who are using, but I think we're kind of treating the symptom instead of the cause.''
