We are a multidisciplinary laboratory supporting research, service, and teaching and training activities. We conduct research and method development for the chemical analysis of drugs, environmental pollutants, natural products and other toxicants of interest in biological specimens and nonbiological samples.
Forensic and Analytical Toxicology
Cannabis Biomarkers Study
Are you 18+ years old and have you smoked/vaped cannabis for recreational or medicinal purposes? If so, you may qualify for this confidential study on cannabis use patterns. Eligible participants who complete the study will receive a $50 cash payment.
- Study details
Cannabis contains more than 100 natural “cannabinoid” compounds. This project will focus on observing the type and levels of various natural cannabinoids present in easily collected specimens, including exhaled breath condensate (EBC), saliva, and urine after smoking or vaping marijuana products, in different type of users. The project will also focus on identifying levels of oxidative stress biomarkers present in EBC.
Qualified participants will be required to meet at the FIU MMC Campus to provide urine, saliva, and EBC samples and to fill out a survey about cannabis/cigarette use. The collection of samples is non-invasive and will consist of simple procedures:
- Urine: participants will pee in a cup, in private.
- Saliva: a swab will be placed in the mouth for up to 5 minutes.
- EBC: participants will breathe normally into a chilled tube for 10 minutes.
The entire process will take about one hour. This will be a one-time meet; there will be no follow up of any sort. All information collected is confidential and will not be used for any other purposes. Participants will receive cash compensation of $50.

- Facility Research
Driven by the FIU and International Forensic Research Institute's research mission, our facility plays a key role in assisting faculty, graduate, and undergraduate students to conduct relevant research using state-of-the-art instrumentation and approaches.
Strong educational support for the law enforcement agencies, academia and forensic laboratories is also provided in our facility. Workshops on modern forensic toxicology techniques, analytical instrumentation, data interpretation and customized method development strategies are offered per request.
Research projects conducted at the facility under the direction of Dr. DeCaprio are focused on the development and application of analytical methods to enhance the value of scientific evidence in analytical and forensic toxicology. These projects have been supported by the National Institutes of Health, National Institute of Justice, private sector clients and other funding sources. Examples of past and ongoing research projects in the facility include:
- Development of ultra-trace LC-QQQ-MS/MS and LC-QTOF-MS/MS methods for the comprehensive screening and confirmation of NPS, including phenethylamines, piperazines, tryptamines, and synthetic cannabinoids, in human specimen matrices such as blood, urine, hair, and oral fluid.
- Systematic examination of the cross-reactivities of NPS with existing immunoassay screening platforms.
- Application of in vitro drug metabolism assays to model in vivo metabolism of important drugs of abuse.
- Development of new technologies for long term monitoring of human exposure to drugs of abuse and chemical warfare agents based on chemical modification of blood proteins.
- Ultra-trace analysis of polychlorinated biphenyl and other persistent pollutant metabolites by dual-column GC and ECD.
- Optimization of GC-EI-MS and GC-NCI-MS separation and analysis of abused prescription drugs, including benzodiazepines, hydrocodone and oxycodone, and their metabolites, in human hair and other biological matrices.
- Evaluation of headspace GC with simultaneous FID and MS detection in blood alcohol and volatiles analysis.
- Detection of nicotine and metabolites in the extracted blood of hookah smokers by online SPE and LC-QQQ-MS analysis.
