Drug Effect Monographs
The drug monographs are for attorneys to reference or discover before trial. The monographs outline a CBI Toxicologist’s general testimony about the potential effects of the drug(s) detected. However, these monographs can used by anyone seeking information about commonly detected drugs and their potential impact on human performance and behavior.
The general information summarized in these monographs may include therapeutic range, half-life, metabolism and general effects.
If you have additional questions regarding toxicology results for your case, please email the author of the toxicology report.

Expert Disclosure Reports (Rule 16)
If an attorney requires the Toxicologist to complete an expert disclosure report, the attorney will need to email the Toxicologist who authored the laboratory report and include the police report. The Toxicologist will review the police report and form an opinion regarding the behavior in the police report in relationship to the drugs detected.
Please remember, in general, a drug concentration cannot be directly correlated to a level of impairment. Tolerance, drug-drug interaction, and drug history all affect an individual differently. An expert disclosure report is not necessary in every case, and all CBI Toxicologists are able to testify as expert witnesses to the effects of alcohol and the drugs detected on human performance and behavior.
The approximate turnaround time for a full expert disclosure report is four (4) weeks.
