ems only

So rumor has it that Narcaine is gonna be available over the counter at stores sometime here soon. I dont know if this is completely true or just rumor through the grapevine, but if it is true what are ya'lls thoughts on it?

I just became an EMT-B. I want to work with a 911 service, but I don't really want to be a firefighter. I know most cities have their EMS and Fire Departments as one. Does anyone know of any medium to large cities where EMS personnel do just EMS and not firefighting? Thanks.
