This is not good but it is an isolated case. My sympathy goes out to the victim. I am against drivers intoxicated on anything and support severe penalties. One incident however does not make statistics. Alcohol is responsible for over 16,000 traffic fatalities every year here in the United States. Pharmaceutical drugs are responsible for over 5000 traffic fatalities in the US and that number is going up rapidly. All traffic fatalities require full blood toxicology for the drivers revealing any substances that they might have been consumed. I have queried police agencies throughout the nation and cannot find one single case where police even bother to keep a statistic on fatal accidents caused "solely" by cannabis intoxication. When asked, police information officers say "there is insufficient data to keep statistics" meaning that incidents are so rare that they don't bother to count them. It is absolutely clear that cannabis is far safer than alcohol and pharmaceutical drugs.
