  1. During a DRE, the evaluator notes the subject has a heart rate of 110 bpm, a blood pressure of 155/95, and is talking rapidly. Which category is the PRIMARY consideration?

    Answer: CNS Stimulants

    Tachycardia, hypertension, and pressured speech are classic CNS Stimulant indicators consistent with cocaine or methamphetamine use.

  2. Which drug category typically produces NORMAL or NEAR-NORMAL pulse rate while still causing significant psychomotor impairment?

    Answer: Hallucinogens

    Hallucinogens may elevate pulse slightly but it often remains near normal, while the subject experiences profound perceptual disturbances.

  3. A subject complains of feeling numb and displays rigid muscle tone with eyes appearing glassy and blank. These signs are most consistent with which DRE category?

    Answer: Dissociative Anesthetics

    Analgesia (numbness), muscle rigidity, and a blank/glassy stare are hallmark signs of Dissociative Anesthetic influence.

  4. Which of the following best describes the pupil size expected in a subject under the influence of Narcotic Analgesics in a normally lit room?

    Answer: Constricted (<3 mm)

    Opioids cause miosis (pupil constriction to <3 mm) regardless of lighting conditions, a hallmark of narcotic use.

  5. Benzodiazepines, barbiturates, and alcohol all fall under which DRE drug category?

    Answer: CNS Depressants

    All substances that depress central nervous system activity — including benzodiazepines, barbiturates, and alcohol — are grouped as CNS Depressants.

  6. Which drug category can produce 'rebound mydriasis' — where pupils appear dilated during the come-down phase even though the drug typically causes constriction?

    Answer: Narcotic Analgesics

    As opioid blood levels fall, the miotic effect diminishes and pupils can rebound to dilated, which can confuse an evaluation if timing is not considered.

  7. Toluene (found in spray paint) and amyl nitrite ('poppers') both belong to which DRE category?

    Answer: Inhalants

    All volatile solvents, aerosols, and nitrites inhaled for intoxication are classified as Inhalants in the DRE system.
