Background Cannabis use has been linked to impaired driving and fatal accidents. Prior evidence suggests the potential for population-wide effects of the annual cannabis celebration on April 20th (‘4/20’), but evidence to date is limited. Methods We used data from the Fatal Analysis Reporting System for the years 1975–2016 to estimate the impact of ‘4/20’ on drivers involved in fatal traffic crashes occurring between 16:20 and 23:59 hours in the USA. We compared the effects of 4/20 with those… 
Crashes on cannabis celebration day
TLDR
Analysis of traffic risks on April 20 found secular trends in relative risks for April 20 reflect evolving driving norms, fluctuating traffic enforcement, changing baseline rates of cannabis use, variable celebration behaviours and rapid growth of the cannabis industry.
Evaluating the Effects of Holidays on Road Crash Injuries in the United Kingdom
TLDR
The proportion of crashes resulting in K SI casualties on public holidays was higher than that on non-holidays, and crashes during the Queen’s 2002 Golden Jubilee had the highest risk of KSI casualties followed by New Year”s Day.
Toward Reducing the Possibility of False-Positive Results in Epidemiologic Studies of Traffic Crashes
44 Large databases, such as the U.S. Fatality Analysis Reporting System (FARS), are often used to study factors that influence traffic crashes that result in injuries or deaths, and how they may be
Research ‘with’ not ‘on’, yes, but with whom and how?
TLDR
There is a need for more ‘Public involvement in the production, dissemination and implementation of injury prevention research’ and Jennifer Woody Collins presents an informed critique of the challenges involved, and provides an elegant response.
Ten common statistical mistakes to watch out for when writing or reviewing a manuscript
TLDR
A list of some of the most common statistical mistakes that appear in the scientific literature and advice on how authors, reviewers and readers can identify and resolve these mistakes and, the hope, avoid them in the future.

Medical Marijuana Laws, Traffic Fatalities, and Alcohol Consumption
TLDR
The negative relationship between legalization and alcohol-related traffic fatalities does not necessarily imply that driving under the influence of marijuana is safer than driving underThe influence of alcohol.
Cannabis effects on driving skills.
TLDR
Evidence suggests recent smoking and/or blood THC concentrations 2-5 ng/mL are associated with substantial driving impairment, particularly in occasional smokers, and future cannabis-and-driving research should emphasize challenging tasks, such as divided attention, and include occasional and chronic daily cannabis smokers.
Fatal Crashes from Drivers Testing Positive for Drugs in the U.S., 1993–2010
TLDR
The profile of a drugged driver has changed substantially over time, and an increasing share of these drivers is now testing positive for prescription drugs, cannabis, and multiple drugs, which has implications for developing interventions to address the changing nature of drug use among drivers in the U.S.
US Traffic Fatalities, 1985-2014, and Their Relationship to Medical Marijuana Laws.
TLDR
State-specific analysis showed heterogeneity of the MML-traffic fatalities association, suggesting moderation by other local factors, which could influence policy decisions on the enactment or repealing of MMLs and how they are implemented.
Alcohol-related relative risk of driver fatalities and driver involvement in fatal crashes in relation to driver age and gender: an update using 1996 data.
TLDR
This is the first study that systematically estimated relative risk for drink-drivers with BACs between 0.08% and 0.10% (these relative risk estimates apply to BAC range midpoints at 0.09%.) the results clearly show that drivers with a BAC under 0.
The effects of cannabis intoxication on motor vehicle collision revisited and revised.
TLDR
Recovery of cannabis-impaired driving is associated with a statistically significant increase in motor vehicle crash risk, and the increase is of low to medium magnitude.
Analysis of trends in the prevalence of cannabis use in Canada, 1985 to 2015.
TLDR
According to data from national population surveys, since 2004, cannabis use was stable or decreased among youth, and rose among adults, and among adults from 2004 through 2015.
Acute cannabis consumption and motor vehicle collision risk: systematic review of observational studies and meta-analysis
TLDR
Acute cannabis consumption is associated with an increased risk of a motor vehicle crash, especially for fatal collisions, and could be used as the basis for campaigns against drug impaired driving, developing regional or national policies to control acute drug use while driving, and raising public awareness.
