A Drug Recognition Expert (DRE) must follow a checklist that breaks down
into twelve components. The next few blogs will examine each step in detail.
Step 6: Examination of Vital Signs
The DRE is required to make precise measurements of the subjects:
- Pulse rate- The rate will be taken at three different times: once during
the preliminary examination, a second time during the vital signs examination,
and a final time during the injection site examination of the subject;
- Blood pressure- The DRE will use a stethoscope and a sphygmomanometer;
- Body temperature- The DRE will use an oral thermometer.
Examining the vital signs is important because this provides important
clinical evidence of drug impairment. For example, depressants and the
narcotic analgesics usually lower the pulse rate while hallucinogens,
cannabis, and most inhalants usually cause the blood pressure to rise.
CNS stimulants, PCP, and dissociative anesthetics usually elevate temperature,
whereas narcotic analgesics cause the temperature to be lower than normal.
