If you were following along with this series from last week, you know that this step in Canada is combined with the check for muscle tone. However, the official twelve steps of the program have separated this step from the check for muscle tone.
In some ways, as I will describe below, this is one of the more troubling aspects of the DRE examination.
The next step in the Drug Recognition Evaluation is to check the subject's body for muscle tone. The rationale behind this is that some drugs will make your muscles rigid and some will make them flaccid, and that will help the DRE officer determine the class or category of drug that a person has taken.
In Canada, this step is combined with the next of the twelve steps, which is to take the subject's pulse and check for injection sites. However, as we are going by the twelve steps individually, I will deal with that next week.
After the preliminary steps are done, taking first pulse and an initial examination, the DRE officer is then able to move on to the more complex eye examinations. The results of these examinations are said to be used to help the DRE officer determine whether a person is impaired by a drug, and identify the class of drugs that is causing the impairment.
Eye examinations are particularly interesting because they do not actually say much about impairment at all. What they do say a lot about is the condition of a person's eyeball and whether that person may have suffered head injuries, has or is suffering a stroke or a seizure, or whether a person may have neurological conditions. Of course, a police officer is in no position to determine any of this.
So read on to find out the three types of eye examinations that are used in the DRE Evaluation.
