Abstracts are now being reviewed by the scientific program committee for the 19th International Conference on Alcohol, Drugs and Traffic Safety to be held in Oslo, Norway, from August 22 to 26, 2010. The organizers thank everyone who has submitted abstracts to help build a strong and exciting scientific program.

 Oslo is the capital of Norway, a modern city beautifully situated at the head of Oslo Fjord. The city limits encompass wilderness areas as well as an array of restaurants almost unparalleled in Scandi­navia. The conference will be held at the Oslo Congress Center, which is located in the central part of the city and only few minutes walk from the Central Railway Station with trains directly from the Oslo Airport.

The conference will start with two workshops on Sunday the 22nd: “Recent Trends in Alcohol and Other Drug Involvement by Drivers Killed in Crashes” chaired by Mr. Jim Fell and “Drug Analysis in Alternative Matrices” chaired by Dr Alain Verstraete. Participation in all workshops is included in the cost of the registration. Also on Sunday will be meetings of the various ICADTS working groups and other committees.

The formal opening ceremony is scheduled on Monday, August 23, 2010. As it has been 60 years since the first ICADTS meeting in Stockholm, a plenary presentation titled “60 Years of ICADTS: Looking Back and Into the Future” will be presented by the President of ICADTS, Dr. Wolf-Rüdiger Nickel, after the opening ceremony. The social program includes a get-together party on Sunday evening, a reception at the Oslo City Hall on Monday evening, and a half-day boat trip on the Oslo Fjord. The conference dinner will be on Wednesday evening.

Authors will receive notification of acceptance of their abstracts in early May. Early registration at a reduced cost will be available until May 30.

After more than 21 years of publication, it is a time of transition for the ICADTS Reporter. We have, of course, lost one of our founding editors. In addition, it is time to redesign and rethink the newsletter. For many years, we have elected to continue with a print publication, but disseminated on line has significant advan­tages, including the ability to expand the length of the current newsletter and include links to Web source materials. We can also maintain a print edition for those who request it.

It is also past time to expand participation in the devel­opment of newsletter content. Over the years, many ICADTS members and associates have contributed material, but the newsletter could benefit from a wider range of contributors. Further, a broader ownership of the newsletter content would make ICADTS a more participatory organization. In partic­ular, the role of contributor to the Reporter could provide valuable experience and exposure to some of our younger members. In addition, soliciting participation from members from low- and middle-income countries could expand the relevance of the organization to a wider part of the world.

To achieve some of these goals, there will be a discussion of ideas for the new, improved Reporter at the general mem­bership meeting at T2010 in Oslo. Any ideas or comments that you would like to contribute in the meantime would be most welcome. Please direct them to the editor, Kathryn Stewart, stewart@pire.org.


The U.S. Department of Transportation announced recently that the number of traffic fatalities for 2009 reached the lowest level since 1954. The projected fatalities for 2009 were 33,963, a 9% decrease from the 37,261 deaths in 2008. The fatality rate per 100 million vehicle miles traveled was 1.16, the lowest on record. The percentage of 2009 traffic fatalities involving impaired drivers has not been estimated yet. To view the preliminary fatality statistics, go to www-nrd.nhtsa.dot.gov/Pubs/811291.PDF


A new survey sponsored by the Insurance Institute for Highway Safety (IIHS) indicates that two of three respondents think that using advanced technology to stop drunk drivers from operating their vehicles is a good or very good idea, assuming the technology is reliable. More than 40% said they would want such devices on their own cars if offered the option. These results are the first indication of what Americans’ think about equipping all vehicles with alcohol detection devices that would be more sophisticated than the alcohol ignition interlocks in some vehicles today. The Driver Alcohol Detection System for Safety (DADSS) program in the United States is a partnership between the National Highway Traffic Safety Administration and the Automotive Coalition for Traffic Safety that is exploring new technology that one day could be developed for widespread use. “The idea is to stop anyone from operating a vehicle if the BAC registers 0.08 or higher, not to prevent drivers from having any drinks at all before getting into their cars,” said Anne McCartt, senior vice president for research at IIHS and an ICADTS member. Even among respondents who said they drink four or more times a week, support for such devices was about 50%. Alcohol-impaired driving is a signifi­cant factor in U.S. fatal crashes accounting for 11,773 deaths in 2008 by drivers with BACs of 0.08 or higher. This represents 32% of all traffic fatalities.


Raising alcohol excise taxes is a highly effective strategy for helping to prevent deaths due to excessive drinking in the United States, according to a systematic review published in the February 2010 issue of the American Journal of Preventive Medicine. The review evaluated 73 published articles and reports that examined relationships between the price of alcohol, exces­sive drinking, and harmful consequences of excessive drinking, including motor vehicle crashes and alcohol-impaired driving.

Higher alcohol prices or taxes were consistently related to:

·         Fewer motor vehicle crashes and deaths;

·         Less alcohol-impaired driving;

·         Lower levels of underage drinking; and

·         Lower rates of violent crime, including homicide, assault, robbery, and rape.

The review found that raising the price of alcoholic beverages by 10% would reduce consumption by about 7%. The review was led by CDC scientists and overseen by the Task Force on Community Preventive Services. Based on the strong evidence from this review, the Task Force recommends raising alcohol excise taxes to reduce excessive drinking and related harms. The Task Force is a nonfederal, volunteer, independent group of public health and prevention experts appointed by the CDC Director.

The American Automobile Association (AAA) has developed a new impaired-driving Web site for criminal justice profes­sionals. AAADUIJusticeLink.com serves as a resource and reference guide for judges, prosecutors, probation and parole officers, and law enforcement. 

AAA based the development of the Web site on an investigation conducted by the Traffic Injury Research Foundation (TIRF), which revealed that criminal justice professionals are not always aware of or familiar with the latest scientific research, new interventions or news reports by other agencies. At the same time, there is a strong desire among these professionals to have access to the latest research and information. Content on the site, which is designed to address some of the challenges of processing drunken driving offenders, was reviewed by a national panel of judges.

Good information exists about effective strategies, policies, and programs addressing drunken driving. However, much of it is fragmented and not easily accessible for practitioners with heavy workloads and time constraints. “This Web site is an excellent resource that can provide practitioners with a current state of knowledge about drunken driving,” said TIRF President and CEO Robyn Robertson.

In 2008, there were 11,773 people killed in the United States as a result of alcohol-impaired driving crashes. “The online tool enables AAA to better serve its members and the public by providing evidence-based information and resources to help stakeholders become more efficient and effective advocates for the reduction of alcohol-impaired driving,” said AAA Traffic Safety Policy and Research Director Jake Nelson.

The Traffic Injury Research Foundation will host the 2010 Annual Alcohol Interlock Symposium, October 17 through 19, in Monte­bello, Quebec, Canada. The theme of this year’s event is “Harmonizing Policies and Practices” with the goal of encouraging and supporting consistency in the use of evidence-based policies and practices across jurisdictions.

With a growing worldwide interest in alcohol interlocks, many countries are currently developing alcohol interlock programs or working to improve and enhance existing applications. To support this trend, the symposium will devote attention to identifying areas in which consistency across jurisdictions is achievable and devel­oping strategies to promote consistency in legislation, in regulations, and in practices (where feasible) for dealing with different classes of drivers. Such an approach can help to reduce duplication, better leverage successes in individual jurisdictions, and minimize conflict stemming from interjurisdictional impediments.

In addition, the symposium will focus attention on the develop­ment and implementation of first offender interlock programs, and engage symposium attendees in the development of appropriate benchmarks and effective strategies to measure and monitor progress in the interlock field in the future. It will also focus on the development of strong evaluation strategies for interlock programs.

This year, the agenda is designed to maximize dialogue, infor­mation exchange and networking. Sessions will involve a mixture of panel presentations and discussion groups to identify oppor­tunities for harmonization in a variety of areas. The agenda will also include updates on areas of common interest and include special workshops designed to meet the needs of interested professionals with varying knowledge about alcohol interlocks. Newcomers are welcome.

Since 2000, the Annual International Alcohol Interlock Symposia has collected the current state of knowledge about alcohol inter­locks. The goal of these symposia has been to advance all facets of alcohol interlocks and support the development of evidence-based programs and practices to reduce impaired driving. Research demon­strates that these breath-testing devices attached to vehicle starters are effective tools to separate drinking from driving. They reduce recidivism by an average of 60%. Today, jurisdictions around the world are strengthen­ing and expanding alcohol interlock programs in a variety of settings.


A recent study examined associations between bar-sponsored drink specials and alcohol intoxication among patrons. Data were collected in a college bar district located in a large campus community in the southeastern United States. Random and self-selected samples of patrons were interviewed after they exited college bars at night on four different nights (N = 383). Anonymous interview and questionnaire data were collected, as well as breath-alcohol concentration (BrAC) readings. Results indicated significant gender differences in patron drinking practices: women were more likely to take advantage of drink specials, whereas men reported greater alcohol expenditures, consumed more drinks, and drank for longer periods. Gender differences in BrAC were very small and not meaningful. Patrons who did not take advantage of drink specials reported consuming more drinks before bar entry than patrons who did participate in these promotions. Participation in “all-you-can-drink” promotions was signifi­cantly associated with higher BrAC readings after ad­justing for covariates and random effects attributable to drinking establishment. Other drink specials did not have significant associations with alcohol intoxication. Study authors concluded that all-you-can-drink special may be the specific discounting practice with the greatest potential for boosting patron intoxication and thus may need to be a stronger focus of alcohol-control policies aimed at improving the beverage service of drinking establishments.

The effectiveness of ignition interlocks at reducing drunk driving has been limited by the ability of driving-while-intoxicated (DWI) offenders to avoid court orders to install the devices. In a pilot program in New Mexico, four Santa Fe County judges imposed home confinement (via electronic monitoring bracelets) on offenders who claimed to have no car or no intention to drive. Interlock installation rates for Santa Fe County were compared with all other counties in New Mexico over a 2-year program and 2-year post-program period. During the two program years, 70% of the drivers convicted of DWI in Santa Fe County installed interlocks, compared to only 17% in the other counties, but when the program was terminated, the Santa Fe installation rate fell by 18.8 percentage points. Mandat­ing the alternative sanction of house arrest led to the highest reported interlock installation rate for DWI offenders. Study authors (Roth, Marques, and Voas) concluded that interlocks provide a method of protecting the public while permitting the offender to drive sober and that rates of interlock use can be increased by mandating house arrest as an alternative sanction.

A recent study explored the extent to which different clinical tests and observations were related to blood Delta-9-tetrahydro­cannabinol (THC) concentrations and to determine whether the combined influence of THC and ethanol was different from either drug alone. A retrospective cross-sectional forensic database study was conducted among drivers apprehended by the police in Norway suspected of driving under the influence of alcohol or other drugs. Investigation was carried out on 589 cases positive for THC only. In addition, 894 cases with THC and ethanol were included. A comparison was made with 3,480 drivers with only ethanol in their blood and 79 drivers who tested negative for either THC or ethanol. Analytical results of blood samples and the 27 clinical tests and observations included in the Norwegian clinical test for impairment (CTI) were examined. No relationship was found between blood THC concentration and most of the CTI tests. Blood THC concentration was, however, related to conjunctival injection, pupil dilation and reaction to light, and to the overall risk of being judged impaired. When THC and ethanol were detected together, the risk of being judged impaired increased markedly. Study authors (Bramness, Khiabani, and Mørland) concluded that cannabis impairs driving ability in a concentration-related manner. The effect is smaller than for ethanol. The effect of ethanol and cannabis taken simultaneously is additive. Source: Addiction, March 10 online edition.
