          - [Docket No. NHTSA-2018-XXXX]

# AGENCY:

National Highway Traffic Safety Administration (NHTSA), Department of Transportation (DOT).

# ACTION:

Request for comment.

# SUMMARY:

NHTSA is reviewing the literature on drug use and driving with the aim of updating its Drugs and Human Performance Fact Sheets that are used by the criminal justice community and others as they address drug-impaired driving. The current edition of the Fact Sheets was released in 2004 and included information on the following drugs: Carisoprodol, cocaine, dextromethorphan, diazepam, diphenhydramine, gamma-hydroxybutyrate (GHB), ketamine, lysergic acid diethylamide (LSD), marijuana, methadone, methamphetamine, methylenedioxymethamphetamine (MDMA), morphine, phencyclidine (PCP), toluene, and zolpidem. NHTSA welcomes comments and suggestions for additional drugs to be considered for inclusion in the new edition of the Fact Sheets as well as relevant research studies that have become available since 2004 that could be included in the updated fact sheets. To the extent possible, such comments and suggestions should be accompanied by information about the drug, including the extent of its use, its pharmacology and pharmodynamics, and how impairing it is for driving, along with references.

# DATES:

Interested parties are invited to submit comments and suggestions on or before September 1, 2018.

# SUPPLEMENTARY INFORMATION:

## Background

In the early 2000s, NHTSA convened a panel of international experts on drug-impaired driving to review developments in the field of drugs and human performance and to identify the specific effects that both high priority illicit and prescription drugs have on driving. The experts represented the fields of psychopharmacology, behavioral psychology, drug chemistry, forensic toxicology, medicine, and law enforcement. That effort resulted in the publication of a document entitled Drugs and Human Performance Fact Sheets (DOT HS 809 725) in June 2004.

Each Fact Sheet covered one of the selected sixteen drugs that impair driving. The selected drugs included over-the-counter medications such as dextromethorphan and diphenhydramine; prescription medications such as carisoprodol, diazepam, and zolpidem; and abused and/or illegal drugs such as cocaine, GHB, ketamine, LSD, marijuana, methadone, methamphetamine, MDMA, morphine, PCP, and toluene. Each individual drug Fact Sheet covered information regarding drug chemistry, usage and dosage information, pharmacology, drug effects, effects on driving, drug evaluation and classification, and the panel's assessment of driving risks. More specifically, the Fact Sheets provided details on the physical description of the drug, synonyms, and pharmaceutical or illicit sources; medical and recreational uses, recommended and abused doses, typical routes of administration, and potency and purity; mechanism of drug action and major receptor sites; drug absorption, distribution, metabolism and elimination data; blood and urine concentrations; psychological and physiological effects, and drug interactions; drug effects on psychomotor performance effects; driving simulator and epidemiology studies; and drug recognition evaluation profiles. Each Fact Sheet concludes with general statements about the drugs' ability to impair driving performance. A list of key references and recommended reading was also provided for each drug.

Since 2004, new research on these and other impairing drugs has become available. As a result, NHTSA plans to evaluate whether additional drugs that impair driving should be included in the Fact Sheets and to add them as appropriate, as well as to update information on the effects of the sixteen aforementioned drugs on driving. NHTSA will base the revised Fact Sheets on the state of current scientific knowledge. The agency intends to design the revised Fact Sheets to continue to provide practical guidance to toxicologists, pharmacologists, law enforcement officers, attorneys, and the general public to use in the evaluation of future cases.

In order to assist on the development of the new edition of the Fact Sheets, NHTSA invites comments and suggestions from the general public on additional drugs as well as relevant research studies that have become available since 2004 that could be included in the updated fact sheets. To the extent possible, such comments and suggestions should be accompanied by information about the drug, including the extent of its use, its pharmacology and pharmodynamics, and how impairing it is for driving, along with references.
