Electronic cigarettes (e-cigarettes), also called vapes, e-hookas, vape pens, tank systems, mods, and electronic nicotine delivery systems (ENDS), are electronic devices that produce an aerosol by heating a liquid typically containing nicotine, flavorings, and other additives; users inhale this aerosol into their lungs (1). E-cigarettes also can be used to deliver tetrahydrocannabinol (THC), the principal psychoactive component of cannabis (1). Use of e-cigarettes is commonly called vaping.

Background: The objective of this study was to characterize unintentional drug overdose death patterns among Hispanic ethnicity/sex strata by residence in New Mexico counties that border Mexico and non-border counties.

Methods: We analyzed medical examiner data for all unintentional drug overdose death in New Mexico during 2005-2009. Logistic and Poisson regression was used to examine the relationship of unintentional drug overdose death with border residence and demographics.

Objective: The abuse of prescription drugs has increased dramatically since 1990. Persons who overdose on such drugs frequently consume large doses and visit multiple providers. The risk of fatal overdose for different patterns of use of opioid analgesics and sedative/hypnotics has not been fully quantified.

Objective: Employees of long-term care facilities (LTCFs) who have contact with residents should be vaccinated against influenza annually to reduce influenza incidence among residents. This investigation estimated the magnitude of the benefit of this recommendation.

Methods: The New Mexico Department of Health implemented active surveillance in all of its 75 LTCFs during influenza seasons 2006-2007 and 2007-2008.

Objective: American Indians and Alaska Natives have the nation's highest morbidity and mortality owing to alcohol but also have opportunities to employ policies that could reduce the harmful effects of drinking. As sovereign nations, federally recognized tribes can adopt policies that are highly likely to have a beneficial impact on alcohol problems. The most recently published nationwide research on American Indian alcohol policies (conducted some 30 years ago) suggested that tribal policies may help minimize adverse consequences related to drinking.

Aims: To determine the contribution of heroin, prescription opioids, cocaine and alcohol/drug combinations to the total overdose death rate and identify changes in drug overdose patterns among New Mexico subpopulations.

Design: We analyzed medical examiner data for all unintentional drug overdose deaths in New Mexico during 1990-2005. Age-adjusted drug overdose death rates were calculated by sex and race/ethnicity; we modeled overall drug overdose death adjusting for age and region.

Background: Excessive alcohol consumption claims more than 75,000 lives in the United States each year. The prevalence of alcohol dependence among excessive drinkers is not well known.

Methods: Data from the 2002 Behavioral Risk Factor Surveillance System (BRFSS) in New Mexico were used to assess the prevalence of excessive drinking, including binge drinking, heavy drinking, alcohol-impaired driving, and alcohol dependence.

Background: New Mexico has the highest rate of drug-induced mortality in the United States. The contribution of prescription drugs to the total overdose death rate has not been adequately described.

Methods: A total of 1,906 unintentional drug overdose deaths occurring in 1994 to 2003 in New Mexico were analyzed.

Aims: To determine death rates from methadone over time, to characterize methadone-related death and to discuss public health surveillance of methadone-related death.

Design: We analyzed medical examiner data for all unintentional drug overdose deaths in New Mexico, USA, between 1998 and 2002.

Measurements: Age-adjusted death rates for methadone-related death, logistic regression models for likelihood of methadone-related death among all unintentional drug overdose deaths and bivariate comparisons within methadone-related death.

New Mexico leads the nation in poisoning mortality, which has increased during the 1990s in New Mexico and the United States. Most of this increase has been due to unintentional deaths from illicit drug overdoses. Medical examiner and/or vital statistics data have been used to track poisoning deaths.

Background: We sought to assess prevalence of behavioral risk factors and evaluate the usefulness of survey data gathered by telephone in the New Mexico border region.

Methods: This study compared behavioral risk factor data gathered from two probability sample surveys administered in 1998-1999, one by means of a telephone interview and the second face to face. Prevalence estimates for medical care access, injury, and chronic disease risk factors were compared by survey mode, overall, and stratified by income level.
