A driver can make a decision not to take drugs and still have a high likelihood of surviving a crash.
And a new Harvard Business School study shows the effects of driving without drugs can be severe.
In a study published in the journal PLoS ONE, researchers at the Harvard Business Schools (HBS) School of Management and the Massachusetts Institute of Technology (MIT) found that drivers who drove without drugs at a rate of one gram of cocaine per 100 miles of driving showed a 62% lower likelihood of having a crash, compared to drivers who were driving at the same rate and not taking drugs.
This finding suggests that the drug-free driving policy may be counterproductive and may not be the best way to reduce traffic deaths.
The study also found that even when the drivers in the study were drug- and alcohol-free, the rate of crash was significantly lower.
Drivers who took no drugs were also less likely to have a crash than drivers who took more than one gram, the study found.
It’s important to remember that these numbers are not the same as what a driver would experience if they took more drugs than a typical driver.
Driving without drugs in this study involved drivers who had a history of drug-related traffic accidents, and there were no drivers who tested positive for any illicit drug.
This is because the drug test results in this paper are only taken when the driver tests positive for drugs.
In addition, the drivers’ impairment levels were measured during the course of the study, which is a bit different than the blood test.
The researchers concluded that even if drivers are drug- or alcohol-impaired, they should be encouraged to take precautions in order to prevent a crash and improve their chances of survival.
“Driving without drugs is not a magic pill that will solve traffic fatalities,” said Professor Paul P. Shostak, the Henry J. Kaiser Family Professor of Management at the HBS and the author of the new study.
“But it can provide valuable information that can help improve our understanding of the health consequences of drug use.”
In the new paper, the researchers analyzed data from the National Highway Traffic Safety Administration (NHTSA) and the National Institute on Drug Abuse (NIDA) to analyze the effects driving without drug use had on the crash rates of drivers involved in accidents.
They then compared this data with the drivers who didn’t drive with drugs, and found that the data showed that the drivers that were drug and alcohol free had significantly lower crash rates.
“We were surprised to find that drug-driving drivers had higher crash rates than drivers not taking drug,” said Dr. Michael J. Schoen, director of the Harvard School of Public Health and the Harvard T.H. Chan School of Global Health.
“This was a finding that was very surprising.”
In their analysis, the team focused on the period between 2000 and 2008, and they used data from more than 50,000 traffic fatalities to examine the drivers and their crash rates, which included the time they spent in the vehicle and in the control vehicle.
“The data we collected over this time period showed that, even when drivers were drug free, they were significantly less likely than drivers in other driving situations to have had a crash,” said study co-author Dr. David P. O’Malley, professor of management and director of Harvard Business and Health Systems.
“For the average driver, taking drugs and driving safely is more than a matter of convenience, but this study demonstrates that it can be a real and significant risk to your health.
Driving safely is not easy, but it’s possible to avoid crashes and have a better chance of surviving one.”
While the drivers of the current study were all drug-impressed, the authors noted that the authors were careful to avoid including drug-using drivers in their analysis.
“If we were to include drug-trafficking drivers in our analyses, we would be excluding those who are also impaired by drugs,” said Shostaki.
“The risk of a driver taking drugs is much higher when they are impaired and driving with impairment.”
The authors noted one other important thing to keep in mind: “The risks of drug impairment in this population may be even greater than the risks of alcohol and other drugs in the population.
This finding does not mean that the benefits of drug withdrawal from driving outweigh the risks.”
Dr. Jodie Bowers, an associate professor in the HSB School of Engineering and Applied Science and the lead author of this study, said the results suggest that the safety of all drivers should be prioritized over those of drug users.
“As we approach the 21st century, drivers and other drivers need to understand that drug use can lead to impaired driving, and that this can happen even if they are not impaired, and it can also happen with alcohol and with other drugs,” Bowers said.
“Drivers should be aware of the risks and use caution when they decide to take a drug
