They do have a lot of meds but not near what he told you. There is close to 100 meds carried on the ambulance including the controlled medicine. They have about 10 meds that are control and must be kept under lock. I no longer know anyone there so I can not get a current list for you. Keep in mind they are a small very remote location where nearest help is more than an hour away.
Remember every thing in Texas is bigger, including the tall tales.
@DFIB The great thing about Texas is services with a good active medical director all levels receive more education and thus are allowed to do more to benefit the patient prior to getting them to the hospital. There are also a number of services that practice a treat and release program rather than transporting all patients. But there are also some medical directors that really just make the ambulance be not much more than a mode of transportation.
