Apparently there is a "bad bunch of speed" for sale on the streets of San Francisco, or at least that's what the police said at the ER last night. We had at least six patients brought in last night, all very much high on amphetamines. It was quite a sight. Despite the fact that they were in restraints and weren't moving much, most of them had heart rates of 140-160 beats per minute for 2-3 hours. To put that in perspective, that is the same rate I aim for during hard running workouts.
