Absolutely. In some cases, the government needs to present the testimony of a toxicologist to make the blood or breath test admissible. However, during cross-examination, the toxicologist can be challenged regarding the conduct of the test and whether proper procedures were followed. Mistakes in the test itself, as well as errors in interpretation and how the test relates to the concentration at the time of driving, can be subjects of the examination.
Additionally, independent toxicologists can be called to testify for the defense, highlighting potential flaws in the test’s conduction and arguing for its inadmissibility. Their testimony can question the reliability of the results and challenge the notion that the person was intoxicated at the time of driving.
Certainly. While breath test results should not be affected by medications, there may be exceptional circumstances where this can happen. The toxicologist can testify or be cross-examined about such possibilities.
In the case of blood tests, the toxicologist can speculate whether medications might have contributed to the appearance of intoxication.
The blood test may also reveal values for specific drugs or medications, which the toxicologist can discuss in terms of their potential impact. Cross-examination can explore the effects of the medication or drug levels on the person’s impairment at the time of driving.
It’s important to note that the breakdown of drugs into metabolites can indicate whether the drug was taken at therapeutic levels over an extended period, potentially rendering it non-intoxicating. This aspect can be questioned during cross-examination.
The toxicologist can assist the defense by examining the blood test comprehensively, including all substances tested for. They can testify about studies or lack thereof, showing whether particular levels of drugs cause impairment or intoxication.
Additionally, the toxicologist can analyze the levels of metabolites to determine if the drug was consumed much earlier, possibly days before, and has broken down into non-intoxicating substances or reached such low levels that they would not cause impairment.
