With legalization of recreational cannabis now in three states and the District of Columbia, and with medical marijuana laws passed in 23 states, there are going to be more impaired people everywhere, including on the road. So what will happen to drivers after cannabis confections, smoked joints or bong hits? Will it be mayhem out on the highway?
The National Transportation Safety Board (NTSB) is as eager to know the answer to that thorny question as anyone. After all, they are responsible for safety on the American road system, among other means and venues of transport. And they collect data – lots of data. In fact, since 1975 NTSB has compiled data on fatal auto accidents and impaired drivers, and they released the results of this decades-long study in November of 2014. Their findings are in a special report entitled “Understanding the Limitations of Drug Test Information, Reporting, and testing Practices in fatal Crashes.”
