Heidi O’Neill, PhD, DABT has studied the effects of various chemicals as both pharmacological therapeutics that may benefit and as toxicants that may pose a threat to human health for more than 20 years. Her focus has been in the areas of neuropharmacology, developmental neurobiology, inhalation toxicology, and human health risk assessment.

Dr. O’Neill has particular experience in:

•DRAM shop litigation
•Drug impairment from drugs of abuse and pharmaceuticals including stimulants (i.e. amphetamines/methamphetamine, cocaine, nicotine, mitragynine/Kratom), benzodiazepines, cannabis, opiates.
•Polypharmacy/drug-drug interactions
•Carbon Monoxide exposure
•Human health risk assessment of flavoring compounds in oral/food products and inhalation devices;
•Textile and fiber toxicology
•Chemical exposure

Expertise:

As a pharmacotoxicologist, Dr. O’Neill has extensive experience in assessing drug and alcohol exposure outcomes and providing expert witness reports. She has also conducted numerous risk assessments of consumer products ranging from oral and inhaled tobacco products to flame-retardant fibers used in mattresses and hair extensions. In addition, Dr. O’Neill has expertise in neurotoxicology and respiratory toxicology, assessing how chemical and biological agents negatively impact the nervous system and respiratory tract.
